Light Review: Olight S2A Baton

26 January, 2017

Olight’s Baton line-up gets a 2xAA powered version at last. Though the beautifully compact S1 is a fantastic light (previously reviewed) my personal ideal form factor is the 2xAA for ease of holding yet remaining compact. It also has the added advantage that AA cells are the easiest to come by, so travelling with or gifting this light is trouble free.

Taking a more detailed look:

Looking very sharp in a clear plastic box with cardboard insert, you get a good look at the light even before you get your hands on it.

Inside the box is the S2A, a spare o-ring, a lanyard and the instructions.

The lanyard has a really nice fabric tube cord and what is that we can see on the attachment loop?

Thank you Olight! It is a wire puller for fitting the lanyard through the small hole in the tailcap. A thoughtful addition and makes life easier. Of course you can do something similar yourself (as I have for some time) but here it is ready to go.

Surrounding the side-switch is a blue PVD ring which matches the bezel.

The blue PVD bezel ring surrounds the S2A’s TIR optic.

The S2A comes with a deep pocket carry clip which can be removed or swivelled to any position to help you locate the power switch.

A very plain and compact tail-cap is used as there is no switch to accommodate.

Behind that TIR optic is a XM-L2 LED.

Looking inside the tail-cap. Note, that unlike the S1, the S2A has no magnet, and also shown here is a plastic insulator disc which is present when you get the S2A, as it comes with 2xAA Lithium cells loaded inside.

Very neatly cut fully anodised square threads are used.

Peering inside the battery tube you can make out the positive contact spring.

It really isn’t much bigger than the two AA cells that power it.

Over the battery tube is a silicon rubber skin-safe grip (more on that later).

An excellent quality of finish even under closer scrutiny. Here is the lanyard hole in the tail-cap.

I said we would be coming back to this, the rubber grip. Well, what a nice surprise it was to see that it glows!

The GITD grip is a very useful location feature.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The indoor beamshot is intended to give an idea of the beam shape/quality rather than tint. All beamshots are taken using daylight white balance. The woodwork (stairs and skirting) are painted Farrow & Ball “Off-White”, and the walls are a light sandy colour called ‘String’ again by Farrow & Ball. I don’t actually have a ‘white wall’ in the house to use for this, and the wife won’t have one!

Starting off indoors, the 600lm beam is way more than you need at this range. There is a defined hot-spot with a very wide spill round it.

For a 2xAA light the 600lm gives it very good mid-range ability, though the spill becomes much less useful out here, with the hot-spot taking over.

Modes and User Interface:

The S2A has six output modes, Turbo, High, Medium, Low, Moonlight and Strobe and a single click-switch on the side.

Basic ON/OFF operation is carried out with a single click of the side switch. The S2A will turn on to the last used constant mode including moonlight (this does not include Strobe).

To change the brightness, while ON, press and hold the switch to cycle through Low-> Medium -> High -> Low -> Medium etc. Release the switch once you have the required output.

There are a few special functions:
Moonlight mode – from OFF, press and hold the switch for 1s until the Moon mode is activated.
Direct access to Turbo – from OFF, double-click the switch.
Strobe – From ON or OFF, triple-click the switch.
Timer – From ON, double-click the side switch. The S2A will blink one or two times. Once means the 3 minute timer is activated, twice means the 9 minute timer is activated. To swap between 3 and 9 minutes timers, double-click the switch.

Timer mode means that the S2A will turn itself off after the specified time, and this can be started from any mode (including Strobe and Moonlight).

Batteries and output:

The S2A runs on 2xAA cells either Alkaline, NiMh, or AA Lithium.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

Please note, all quoted lumen figures are from a DIY integrating sphere, and according to ANSI standards. Although every effort is made to give as accurate a result as possible, they should be taken as an estimate only. The results can be used to compare outputs in this review and others I have published.

___________________________________________	________________________________	________________________________
Olight S2A using specified cell	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
Turbo – AA Eneloop	596	0
High – AA Eneloop	282	0
Medium – AA Eneloop	132	0
Low – AA Eneloop	17	0
Moon – AA Eneloop	Below Threshold	0
Turbo – AA Lithium	546	0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 3500 lx @1m giving a beam range of 118 m.

There is parasitic drain but is incredibly low at 1uA (216 years to drain the cells).

What is very impressive with the S2A is that 600lm Turbo output. This is pushing it for 2xAA, and only with the Eneloops did I get this peak measurement. Like many other lights, the output drops after 3 minutes down to its much more normal 270lm level which the AAs can keep up with. This output is very well regulated for 1h 15m, after which is starts to drop off. There is a sharp cut off around 1h 40m, but you get plenty of warning the output is dropping.

Troubleshooting

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The S2A in use

For anyone that has read my other reviews of the Olight Batons, you will already know I think they have got the UI spot on. For non-tactical use, the side switch is king, falling nicely under your thumb and being very natural to use. Then there is the simple control options but that give your direct access to moonlight, Turbo, Strobe and last used modes; what more could you want?

I wouldn’t have thought it, but the timer mode has also proven useful letting you get tucked up in a sleeping bag, or even to give you a way of keeping a rough track of time. I’ve certainly used it that way when only wanting to be out for so long and getting easily distracted, the 9 minute timer switches the light off which I pop straight on again and head back. You are sure to find several uses once you try it out.

Having the rubber grip does make it very secure to hold, and stops it from feeling cold when temperatures are low. The best part of this is the GITD feature. The glow does last several hours, but you will need dark adapted eyes to see it after an hour or so, and it might not make it through a long night. Even so this is a great addition.

The brightness of the hot-spot did surprise me a little as I was hoping for a beam with slightly more flood. (This is a personal preference as unless I want a thrower, I always find full flood easier to use for my needs.) Indoors I have felt some hot-spot blinding and have had to use a ceiling bounce instead of direct illumination. Outside that hotspot does become useful, so there is a good balance making this an all-rounder.

Negligible parasitic drain allows for this to be loaded up and on standby without worrying if your cells are running down, so I applaud Olight for that excellent 1uA drain; I won’t be worried in 216 years time that the cells have run down!

Although I also have a preference for single cell lights, as you don’t have to cell match, the 2xAA format does give you quite a bit more power and runtime plus the benefit of being a good size to hold. This really hits a sweet spot for me in format and usability and is now a favourite EDC light.

Light Review: Fenix TK15UE (Ultimate Edition)

27 December, 2016

Fenix have been taking classic lights from their range and creating ‘Ultimate Edition’ versions, pushing their performance to the maximum. The TK15 has now been ‘UE’ed to make the TK15UE with uprated output, throw and a new stainless steel bezel.

Taking a more detailed look:

The TK15UE comes in Fenix’s standard packaging.

Included with the TK15UE are the instructions, a holster, a lanyard, a couple of O-rings and a spare switch boot.

Before we move on, the holster is worth lingering on a little longer.

On the back there is a choice of a D-ring, fixed loop, and Velcro closing loop.

There is something a little different here. The holster flap has a retaining strap over it and inside the holster it is fixed with Velcro.

You can just see inside that the flap extends most of the way down the inside of the holster.

The entire flap can be undone and either removed or adjusted to loosen or tighten the fit, or even accommodate a different length light.

As supplied, the holster is correctly configured for the TK15UE.

The most obvious sign that this is something a bit different to the previous TK15s is the Stainless Steel bezel.

Let’s have a look at how the TK15UE and an older TK15 compare. This is the TK15C. So the holster is more than the basic one the TK15C comes with.

Dimensions are all very similar. The TK15C I’m comparing with here has had the clip removed as well as the tactical grip ring because it has been used gun-mounted.

Going in close to the engraving of the model, the knurling and mode switch.

All the edges of the clip are nicely rounded, and there are no sharp corners to eat away at your pockets (just the knurling under the clip).

The switch button does protrude, so no tail-standing, and it has two raised areas to provide the switch with some protection from accidental activation.

As with the stainless bezels on other Fenix lights, the edges have been bevelled to make them kind to the holster and your pockets.

The inner edges of the bezel are crisp without being sharp.

Fenix’s preferred trapezoid threads are used.

The end of the battery tube is the electrical contact that connects to the tail-cap contact.

Inside the tail-cap are the battery tube contact and the negative terminal sprung contact.

With the TK15UE, the head will unscrew.

As the battery tube can be removed we can get a good look at those contacts in the head.

Just like previous TK15 models, the TK15UE has a smooth reflector.

In the centre of that reflector is the CREE XP-L HI V3 LED.

Looking straight into the TK15UE’s reflector.

The TK15UE is one of the more compact single 18650 lights. Not as compact as the small-head types such as the PD32, but it does have a big enough reflector to give it some punch.

You can take off the tactical grip ring by unscrewing it.

Unless you buy the optional thread protector you will see the grip ring threads.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

Indoors the TK15UE is not at its best, as it is quite a throw orientated beam. The hotspot is bright and well formed. Spill is relatively dim and narrow but usable. There is enough balance in the beam to make it OK indoors.

But it is when you get a bit more range that the TK15UE really starts to shows what it is made of. The throw belies its compact size, and with the ‘UE’ upgrade it is a really punchy little light.

Modes and User Interface:

To control the TK15 UE there is the forward-clicky tail switch, and the mode selection switch just behind the head.

Click ON (or half press for momentary action) the tail switch to access the last used constant mode. With the tail switch on, press the mode button to cycle though the modes.

The standard modes are Low, Medium, High and Turbo.

There is a hidden Strobe mode accessed by holding the modes selection switch in for 1s. Strobe is not memorised as a last used mode.

Batteries and output:

The TK15UE runs on 18650 or 2xCR123.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

___________________________________________	________________________________	________________________________
Fenix TK15UE using specified cell	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
Turbo – Fenix ARB-L18-3500	776	0
High – Fenix ARB-L18-3500	377	0
Medium – Fenix ARB-L18-3500	164	0
Low – Fenix ARB-L18-3500	14	0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 31100 lx @1m giving a beam range of 353m.

There is no parasitic drain.

I was slightly surprised by the Turbo output runtime trace as unlike most Fenix lights the TK15UE does not appear to run with a regulated output. The trace was recorded using cooling, so it is unlikely that this is due to overheat protection, instead the TK15UE seems to run at maximum output with that output sagging as the cell becomes depleted. However saying that, you do get a full hour of runtime at more than 600lm, so overall the performance is still good. (This was run using Fenix’s latest ARB-L18 3500mAh cell.)

Troubleshooting

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The TK15UE in use

By separating the mode selection to a side-switch Fenix have allowed proper momentary use of that forward-clicky tail switch. This makes for a really easy and intuitive interface and keeps things simple for any user.
Fortunately the strobe mode is reasonably well hidden and is not memorised; I’m surprised anyone still includes strobe. As those that follow me will know, I’m certainly no fan of strobe and most true tactical users I know are aware that if you strobe another person, you strobe yourself as well, so your are better off not using it at all. Thankfully with the TK15UE you need never come across strobe and can use the four constant output modes without tripping over strobe.
The TK15UE manages a balance between hotspot and spill that, although it is more oriented towards throw, is still usable at indoor distances.
When using the holster with the TK15UE inserted bezel-down, the bezel does catch in the holster before getting all the way in. Used bezel-up, this does not happen. It seems to be due to the adjustable flap taking up more space inside so the bezel catches on the inside of the holster. To get it all the way into the holster bezel-down you need to twist the TK15UE as you insert it.
There are smaller single 18650 lights, but the TK15UE is still compact enough to make it easy to carry, yet that slightly larger head is enough to give it a nice strong beam. Even with the upgrades to the head and LED, Fenix have kept the character of the TK15 but made it significantly brighter.
I’ve always felt the TK15 was an unsung hero in the Fenix line-up, quietly getting on with the job while others took the glory. In the Ultimate Edition, the TK15UE can now take some of the limelight and hopefully get a bit more recognition.

Review Summary

Significantly boosted output compared to previous TK15 models.	Turbo output not regulated.

Light Review: Olight R50 Seeker

12 December, 2016

Olight’s R50 Seeker is a handy sized powerhouse using a 26650 cell and the XHP50 LED allowing it to give you 2500lms in an easily carried package; built-in USB charging adds to its flexibility.

Taking a more detailed look:

The R50 arrives in something more like a presentation box than just ‘packaging’.

The box has a lid which is held shut with magnets.

Taking everything out you have the R50, instructions, charger, charger plug adaptor, USB cable and lanyard.

Before you can use the charger you need to fit your local plug adaptor.

The adaptor clicks into place.

The charger is multi-voltage and with a 2.1A output.

Separating out the USB cable and lanyard. The lanyard has a very nice ‘fabric tube’ wrist loop.

A good looking light with blue bezel an switch rings.

Looking from the rear you can see the USB charging port cover in the tail-cap.

The main power switch is low profile, but big enough to be easy to use.

Diving in close to the quad die XHP50 LED.

Surrounding the LED is a textured reflector.

Flipping round to the other end, there is a rubber charging port cover in the tail-cap.

Pulling this aside exposes the micro-USB socket.

Inside the tailcap, there are three contacts; a ring contact for the end of the battery tube, and two sprung button contacts.

The tail-cap end of the cell has two contacts to match the two in the tail-cap.

Threads are square cut.

Supplied with the R50 is a proprietary Olight 26650 cell.

This cell has the twin contacts on the ‘negative’ end of the cell, and an arrow on the side to indicate which way to insert it.

Peering inside the battery tube to look at the positive contact.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The R50 manages to combine a very wide spill with a bright hotspot.

Taking it outside and that wide beam lights up everything near you and the broad hotspot has good range.

Modes and User Interface:

Before we get into the controls, we need to charge the R50. After connecting the USB cable there is a red charging indicator light next to the USB socket.

Once fully charged this turns green.

To turn ON to the last used constant mode, click the side switch once.
To turn ON to Turbo directly, double-click the side switch.
To turn ON to Strobe, triple-click the side switch.
To turn ON to Low mode directly, press and hold the side switch for 1s.

To change brightness level, with the R50 ON, press and hold the switch to cycle through Low – Medium – High – Low etc.

To turn OFF, click the side switch.

There is a memory for the last used ‘normal’ mode (Low, Medium, or High) but High is only memorised for 10 minutes after which the R50 goes back to Medium.

There are two ways to lockout the R50:
1. Unscrew the tail-cap a half turn.
2. Press and hold the side switch (from OFF) for over 2s. (After 1s the R50 will come onto Low, but after 2s it will go off again as it enters lockout.)

To exit lockout use the corresponding method to the lockouts above:
1. Tighten the tailcap.
2.Press and hold the switch for 3s.

Batteries and output:

The R50 Seeker runs on a proprietary 26650 cell. The instructions do not mention support for standard 26650 cells, however I have tried this and the R50 does function (though does not accommodate very long cells) apart from the charging not working.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

___________________________________________	________________________________	________________________________
Olight R50 using supplied 26650 cell	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
Turbo	2479	0
High	1281	0
Medium	440	0
Low	39	0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 22000 lx @1m giving a beam range of 297 m.

There is parasitic drain at 52uA. When using the included 4500mAh cell, it will take 9.87 years to drain the cell.

A very impressive output for a compact light. During extended use, the Turbo stepping down from nearly 2500lm to 1800lm is not noticeable and while running at 1800lm starts to generate a good amount of heat. Even with the step down at 30 minutes to around 1650lm you don’t really notice, and it is only once you get to about 50 minutes and the R50 steps down to the medium output of 440lm that you see a drop in output.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The R50 Seeker in use

For such a usable and useful light I am disappointed Olight did not include a holster. Even though it uses the 26650 cell, so has a thicker tube than the common 18650 size light, Olight have kept the overall size very compact and comfortable to hold. It may not be jeans-pocket sized, it is easily coat-pocket sized.

Output is extremely impressive and does meet the specified 2500lm. This does drop to 1800 after 3 minutes, but that reduction is barely noticeable and the R50 continues to impress. Everyone who has seen me using the R50 has said “that is bright” and asked what it is; a real talking point.

One area where I think Olight has really cracked it, is the interface. It is the same, or very similar, to many of the other Olight lights with a single side switch, so you will recognise the way it works. Giving the user direct access to the maximum and minimum levels, whatever you last used, makes this a real winner. Another nice touch is the way that the ‘normal’ mode (from a single click of the side switch) will not memorise High beyond 10 minutes of being off, it means that whatever you were doing with the R50, worst case you might get Medium if you turn it on without thinking. Not so much you get blinded and yet powerful enough.

These days you won’t really find yourself unable to find a USB charger at work or at home. The R50 comes with a quality 2A charger anyway, but while you are away from home you will be able to top up the R50 easily enough. The instructions specifically don’t mention using any other 26650 cells, but being the rebel I am, I popped one in. Clearly the charging function is not going to work, but the R50 itself did work, so you can carry a spare 26650 if you want. Just beware that the R50’s tube is not that long, so some 26650 cells may be too long. Check it fits before you rely on it.

There is some shaping at the head, but the R50 effectively has no anti-roll feature, you need to put it down head-down or tail-down. It does tail-stand very well.

Running the R50 on Turbo also provides you with a hand-warmer as it does heat up quite a lot. Given a cold evening, this certainly is a welcome feature. If you decide to tail-stand the R50 on Turbo you will hit the over-heat protection, so expect the output to drop if you let it get really hot.

Personally I find the R50 hits a real sweet spot in terms of size, ergonomics and output. Give me a side-switch light any day, add to that a cell which is large enough to sustain a significant output and a great all-rounder beam, keep it small enough to pop into a coat pocket and you have a winner. I’ll forgive it the proprietary cell for the fact that this has convenient built-in USB charging, doesn’t need anything else to be bought to use it, but can use standard 26650 cells, so gets round the normal limitation of proprietary cell lights.

Light Review: Surefire Sidekick (Compact Fob Light)

13 October, 2016

Though not the first to make a USB rechargeable keychain light, Surefire have applied their philosophy of ‘excellence in illumination’ to this EDC essential.

Taking a more detailed look:

The Sidekick comes in a cardboard blister pack.

Inside is the Sidekick itself, a short USB charging cable, a metal clip and the instructions.

The underside of the Sidekick has a metal heat sink panel with the model engraved onto it.

At the top is the power button and a moulded Surefire logo. The main body is a tough plastic and has a split ring at the rear.

On the angled corner at the front you can see the micro-USB port for charging.

I only noticed the small piece of plastic case under the micro-USB port was cracked when I was preparing these photos. This has not affect the function at all.

Set into the front is Surefire’s MaxVision Beam reflector assembly. This has a multi-faceted reflector surface to smooth out the beam without the losses of a textured reflector.

Looking straight into the faceted reflector at the Cree XP-G2 LED. (For some reason Surefire don’t specify the actual LED anywhere in the documentation.)

Plugging in the micro-USB cable to charge the Sidekick.

Even the compact metal clip has ‘SF’ on it.

The split ring is very stiff, so getting the clip on isn’t easy, but its not going to come off by mistake.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

Since the days of the Solitaire keychain light, I’ve always had a compact EDC light on my keys. This shrunk to the photon size button cell type, but those really only served as a last ditch light, so the size I used grew again to include a USB rechargeable or AAA powered light. The beam of the Sidekick is a revelation in keychain lights, with its wide floody beam (with no glare) and plenty of power.

Just look at this beamshot and you probably think we were looking at something you wouldn’t attach to your keys. A really excellent EDC beam.

Modes and User Interface:

The Sidekick has three output levels Low, Medium, and High.
From OFF, press the power switch to select Low, press again within 2s to change to Medium, press again within 2s of the last press to get High, and once more cycles to OFF.
If you are using either Low or Medium, if you wait over 2s before pressing again, the Sidekick will turn OFF (instead of going to the next mode and then OFF).

There are no indicator lights on the Sidekick, so no charge or low battery indicators. Instead the Sidekick uses its main LED. For low battery, the output simply reduces sharply to a lower level and starts to fade out. There is no sudden turn off, so while there is no actual ‘warning’ it is clear you are low on power.

For charging, the main LED is used as the indicator. With the USB power connected, the LED blinks to indicate the Sidekick is charging. During the charging process the LED sometimes comes on steadily for a few seconds then has a series of blinks. I’ve not so far managed to determine if there is an actual pattern to this. Ultimately, once fully charged the main LED comes on steadily at the low level and stays on as long as power is connected.

The default order of the modes is L-M-H, but this can be reversed to H-M-L by carrying out the following steps:

1. Plug in the charger.
2. Press the switch three times until the High level is activated.
3. Leave the Sidekick On for 5 seconds or more, then press the switch once to turn Off.
4. Unplug from the charger and test the sequence.

To return to L-M-H, repeat the previous steps except in step 2 you press three times to activate Low.
(Stopping on Medium at step 2 does not do anything.)

Batteries and output:

The Sidekick runs on a built-in 640mAh Li-ion battery.

Surefire have commented that the charge rate is fixed around 450mA, but it always seems to charge faster than the instruction manual, or this information, would suggest. In my experience (with a good charger) even fully depleted, it takes less than an hour to charge.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

___________________________________________	________________________________	________________________________
Surefire Sidekick using built-in cell	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
High	320	0
Medium	60	0
Low	3	100

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

There is parasitic drain but as the light is sealed this could not be measured. During normal use over a period of over 6 months, the Sidekick has never noticeably self drained.

For such a compact lightweight light, the Sidekick has a fantastic performance on High. Not fully regulated, the output does however remain above 250lm for a full 45 minutes – very impressive for a keychain light.

The Sidekick in use

Though it is compact, the Sidekick is relatively large for a keychain light. It gets away with this thanks to not being heavy and the plastic housing seems to help reduce its overall presence. Here it is shown next to a AAA keychain light and a photon button cell light.

With this extra size and relatively high cost (compared to its rivals, and especially in non-US markets), the Sidekick needs to work well to justify itself. The excellent beam and 300lm output do just that.

Ideally I prefer a smaller keychain light, but the extra size does make it more stable to hold, and you just don’t get that kind of output and runtime from something smaller and lighter.

If the housing were 100% plastic there would be heat issues, but Surefire have used a metal side panel which allows it to conduct heat out of the Sidekick. When using the High output this can get quite hot to the touch.

Perhaps the biggest annoyance for me has been that it is very similar in size to my car key, and when reaching into my pocket I now have to do the ‘pocket juggle’ of my keys to identify if I’ve grabbed my car key or the Sidekick.

The power button is quite stiff and has little feel to the click. The stiffness is an advantage in not having accidental activations (none so far, which I cannot say about other keychain lights), and eventually you do get some feel for the subdued click.

Not being a tactical light, the modes being L-M-H is ideal as for general EDC you most often only need a little light. One disappointment is the use of visible PWM in the Low mode. Medium and High have no PWM, and if only that Low mode was the same it would be much better.

Battery capacity is really great with the 640mAh cell always having plenty of output and runtime for everything I’ve thrown at it. Even with some unexpected night time strolls needing the path to be lit, using the full 300lm and plenty of other On/Off cycles to check things, and I’ve not needed to keep on recharging.

Recharging is one of those ‘love it or hate it’ things due to the main beam being used as a charging indicator. As it has never taken more than 1 hour to charge I haven’t needed to charge it overnight, so it is not that the main beam flashing and then going onto Low disturbs my sleep. However, the flashing can be annoying if you are in a room with lowered lighting. I was surprised by the Sidekick turning on the Low output once charging is complete, but actually it is a very clear indication that charging has finished, and even with a good charging circuit, it is never a good idea to leave any device on charge for a long time for no reason. The Sidekick tells you clearly to take it off charge. You can look at this either way, and to start with I thought it was not good, but having got used to it find it works pretty well.

The beam is very good, with a smooth floody profile and a neutral tint, which makes it so much better to use than lights with a 5mm LED or those with a more focused hotspot. This combined with the 300lm output, which is reasonably well maintained for a full 45 minutes of constant runtime, make this a really strong performer and the slight size penalty you pay is worth it.

Light Review: FOURSEVENS Preon P1 and P2

21 June, 2016

FOURSEVENS’ Preons have been very popular and well regarded AAA powered EDC lights. Being time for a reboot, here are the current updated versions of the Preon P1 and P2.

(And yes, they do have a high efficiency XP-L LED.)

Taking a more detailed look:

Presentation is great with FOURSEVENS’ standard clear plastic box packaging.

Each Preon comes with one set of AAA Alkaline cells, two spare O-rings and the instructions.

A quick look at the previous generation Preon P2 (in toxic green) with the latest generation Preon P1 and P2.

A feature of the Preons is the metal switch button. Prior to anodising, this has been engraved with the FOURSEVENS logo.

The stainless steel pocket clip is a well finished and has a well-suited tension (not too stiff) to the size and weight.

Just above the head of the light the FOURSEVENS logo is laser engraved through the anodising.

On the opposite side the model is engraved.

A view of the contacts inside the head. (This is the same for the P1 so the P1 is not being shown.)

The threads are a standard form, and are well lubricated. (This is the same for the P1 so the P1 is not being shown.)

You can unscrew the switch cap and take the clip off, but this does not give access to the battery chamber.

An XP-L LED sits in a small textured reflector.

Looking straight into the small reflector.

The clip on the P1 is the same, but here is a view from a different angle.

The P1 also has a metal switch cap over a forward-clicky switch.

The new Preons feature a fully textured body with grooves for grip along the entire length.

With it shorter battery tube it is just possible to show the positive contact spring terminal.

For scale, each Preon is shown with its AAA cells next to it.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

For this set of beamshots, the exposure has been kept the same for the P1 and P2 to show their relative brightness.

Starting indoors with the P1, it has plenty of power for your close range EDC needs, with a nice wide, soft, hotspot and wide spill.

With the P2 it looks the same just brighter, as the P2 has double the output of the P1.

At outdoor ranges the Preons struggle as they are only AAA powered and have a flood orientated beam. These exposures are long to show anything. The P1 doesn’t have much impact.

With the same exposure to allow direct comparison, the P2 looks a bit better, but this is a long exposure, so don’t expect too much at this range.

Modes and User Interface:

Both the Preon P1 and P2 operate in the same way with a forward-clicky switch.
In total, there are 7 output modes which can be used – Low, Medium, High, Strobe, SOS, Beacon (high), Beacon (low).

To fine tune the Preon to your needs, you can set one of 5 possible ‘Configurations’ which have only certain modes available:
Configuration 1: High
Configuration 2: Previous, High, Low
Configuration 3: Previous, High, Strobe
Configuration 4: Previous, Low, Medium, High, Strobe
Configuration 5: Previous, Low, Medium, High, Strobe, SOS, Beacon (high), Beacon (low)

By default, configuration 2 is set. To change configuration, rapidly press the switch 10 times within 2s, holding or clicking the tenth press.
At this point the Preon will flash 1 to 5 times to indicate the selected configuration.
Quickly turn the Preon OFF and ON again to move to the next configuration, and repeat until you have the desired configuration. To memorise the setting, turn the Preon OFF for 5 seconds.

The Preon has a memory of the last mode used. This is relevant only on Configurations 2, 3, 4 and 5.
To change to the next mode in the chosen configuration, turn the Preon OFF and ON again within one second.
As shown in the Configuration list above, when you first turn the Preon ON, you get the ‘previously used’ output mode. When you then change mode, you jump to the start of the set of modes for that Configuration.
For example, if you are set to Configuration 5 and previously used Strobe, when you first turn the Preon ON you get Strobe, and when changing modes the next mode becomes Low, Medium… (In this example you do not go to SOS as the next mode).

Batteries and output:

The Preon P1 runs on 1x AAA and the P2 on 2x AAA; either Alkaline of NiMh cells can be used (maximum input voltage 3.0V).

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

___________________________________________	________________________________	________________________________
P1/P2 using AAA Eneloop	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
P1 – High	127	1000
P1 – Medium	63	1000
P1 – Low	7	1000
P2 – High	259	950
P2 – Medium	137	950
P2 – Low	33	950

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity for the P1 measured 200 lx @1m giving a beam range of 28 m.
Peak Beam intensity for the P2 measured 600 lx @1m giving a beam range of 49 m.

There is no parasitic drain.

The two Preon models are also shown next to the Bolt-Mini, as this was another FOURSEVENS AAA light I have tested (check index page for this review). Thanks to its two AAA cells, the P2 is the only light to display full regulation in the output. With only one AAA, the P1 is always pushing this limited power source, but runs with a pretty consistent output after the initial drop from the 3 minute ‘burst’ at turn-on.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The Preon P1 and P2 in use

When compared to the previous generation Preons, these new versions are slightly chunkier, and initially I was not entirely convinced, as the point of an AAA light is to be very small. But then I remembered that as much as I love the older P2 shown in the photos, it was always a bit slippery. The smooth body wanting to slide around and not giving much of a grip.

With the new Preons having a grip pattern over the entire length of the light, no longer do you get this slippery feeling. One further observation though, is that these grooves tend to pick up pocket fluff nicely, which does somewhat spoil the look.

Personally I preferred the previous UI where it had no memory, but for some a memory is a requirement as you can pre-select the output you generally use. However, as the memory only affects the mode at switch-on, after which the mode selection goes to the first of the modes in the current Configuration, it only takes one mode change to return to Low (if Low was not the previously used mode). On the P2, the Low is much brighter than it used to be (3lm in the previous version) as it is now 33lm. The P1’s low is still pretty low at 7lm so if you need a lower output the P1 is the way to go.

Unfortunately another aspect has changed in the new version, PWM is rearing its head. The previous P2 had PWM but at 2500Hz and was not noticeable to the naked eye; the new version has PWM at 1000Hz. On High and Medium this has not really been visible, but on Low, I do catch the strobing effect out of the corner of my eye. A minor irritation and not what I would expect of FOURSEVENS. It slightly takes the edge off what could be a great update to this well loved series.

It used to be more common for smaller EDC lights to go with a reverse-clicky switch, but as in earlier versions, the Preon does use a forward-clicky and gives you that immediate response to pressure on the switch.

A great feature that has been added to the Preons is the user-changeable configuration that allows you to limit which output modes can be selected. You don’t get to choose which modes are included in a ‘configuration’ but you can choose one of the five available ‘configurations’ to best suit your needs. This user configuration has great potential and I hope FOURSEVENS expand the number of configurations that can be chosen from including a lower level in the P2, and perhaps configurations with no memory. Remember when choosing your configuration that the new Preon has a memory so starts on the last used mode.

With the small power source of AAA, the added efficiency of the XP-L (though only around 9%) makes a difference. Thanks to the XP-L having an XM-L2 size die in a smaller package, it is compact enough to be fitted into the Preon’s head and provide a great EDC beam.

The new Preon doesn’t just have a new body design, it has user-configuration and an XP-L LED.

Light Review: Olight M23 JAVELOT

16 June, 2016

Olight have taken the popular M22 Warrior and updated it by giving it the ‘JAVELOT’ treatment. The result is the M23 JAVELOT. After the success of the first few Javelot models, Olight have been updating a few existing models, like the S30RII and M22 into Javelot versions with uprated emitters and throw.

Taking a more detailed look:

The M23 JAVELOT is supplied in a sturdy plastic case.

Everything is held in cut-outs in the foam liner.

Starting off with a look at the unconventional holster design. The retention flap has a hole cut into it through which the tail-cap protrudes. This gives access to the tail-cap switch.

Both sides of the holster feature cell holders. For CR123 these are not that secure, but for 18650 they work well enough (though the cell is partly exposed and could be damaged.

Now we see why you might want access to the tail-cap switch while the light is in the holster. The bottom of the holster has a hole cut in it allowing the M23 to be used while fully inside the holster.

On the back is a Velcro belt-loop and small D-ring.

Supplied with the M23 is the holster, CR123 cell holder, diffuser, spare O-rings, a lanyard, the instructions and two CR123 cells.

Externally the main difference between the M22 Warrior and the M23 JAVELOT is the stainless steel bezel.

The entire head has heat-sink fins along it.

A side view of the steel pocket clip.

Another view of the strong pocket clip.

The pocket clip fits into a cut-out on the battery tube, and the grip-ring has a notch in it which fits over a lug on the steel pocket clip. This prevents the pocket clip or grip-ring rotating.

With the supplied diffuser fitted, the stainless bezel is hidden. You can’t fit the M23 into its holster like this.

Inside the tail-cap, the negative terminal is a sprung plunger. The tail-cap/battery tube connection is hidden and uses a special design to fit into the conical opening at the end of the battery tube.

The switch is large and textured.

Threads on the tail-cap end of the battery tube are square cut and fully anodised.

Threads on the head end of the battery tube are square cut and bare aluminium.

Unscrewing the battery tube fully shows the contacts in the head, with the positive spring-terminal, bare threads plus ring-terminal for the twisty interface.

For its excellent throw the M23 uses a deep, smooth reflector.

Looking straight into the reflector.

And a closer look at that LED. Olight describe this as a ‘customised high intensity CREE XP-L LED’.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

The beam does have a reasonably warm tint and as expected for a JAVELOT light, there is a very strong hotspot. This might be a bit fatiguing to use indoors which is why there is a diffuser supplied.

Popping on the diffuser and we have an entirely different experience (the exposure here is the same as without the diffuser).

Outdoors it is clear this is a thrower!

And just to see, the result with the diffuser is good (the exposure here is the same as without the diffuser).

But we need more range, so here we are at a golf driving range with the 250yard marker easily visible, and beyond.

Modes and User Interface:

The M23’s output is controlled by the forward-clicky tail-cap switch and twisty interface at the head.

Available modes include High, Medium, Low and Strobe.

From OFF, either click or half-press and hold to turn onto the last-used constant output mode.
From ON, either click the switch or release the half-press to turn OFF.

From OFF, double-tap and click (or hold) the switch to activate High.
From OFF, triple-tap and click (or hold) the switch to activate Strobe. While strobe is activated, the twisty interface does nothing.

From ON, loosen-tighten the head to cycle through High -> Medium -> Low -> High etc. (it is as the head becomes tight again that the mode changes). Tightening the head while the M23 is OFF does nothing.

This operation allows you to set the output to Low, but still have direct access to High (double-tap) and Strobe (triple-tap) via the tail-cap switch alone.

Batteries and output:

The M23 runs on either 1x 18650 or 2x CR123.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

___________________________________________	________________________________	________________________________
Olight M23 JAVELOT using specified cell	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
High – CR123	950	0
Medium – CR123	361	0
Low – CR123	38	0
High – 18650	918	0
Medium – 18650	365	0
Low – 18650	38	0
Diffuser Test High – No Diffuser	861	0
Diffuser Test High – Diffuser	584	0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 39700 lx @1m giving a beam range of 398 m.

There is no parasitic drain.

Overlaying the two runtime traces from 2xCR123 and 1×18650 shows that CR123 initially gives a slight boost in output for the first few minutes before the output for both power sources converge. This happens during the controlled output reduction to just over 600lm for the regulated level. CR123 runs out of steam earlier (as expected) falling out of regulation at around 35 minutes. 18650 holds regulation until about 55 minutes with a less sharp fall-off.
Both traces end with a period of inconsistent flickering output instead of cutting out.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The M23 in use

I’m going to get the main issue out of the way first – the holster. I can see what was intended with the holster, but for me it presents three main problems in use. Firstly getting the flap over the tail-cap, so you can secure it is far too difficult as it is a tight fit and doesn’t easily go over the M23’s tail-cap. It is possible that as it wears it will become easier, but this will only be due to the material softening and becoming frayed. Secondly the tail-cap switch is exposed, and with the design used for the tail-cap connection, it cannot be locked out; no lock-out and an exposed tailcap is going to lead to accidental activation. Lastly on the holster, though the ability to carry spare cells is welcome, by leaving them partially exposed, they can be lost or damaged; I don’t trust the cells holders myself.

The holster is full of good ideas, but I don’t find them to work terribly well.

Onto the M23 itself, and things swing back to positive – it is a typical single 18650 size light, with solid build quality; you definitely would feel confident that you could use the strike bezel if needed.

Rather than having the typical tail-cap to battery-tube connection that uses a battery tube with a flat end (most common), in the M23, Olight uses a design where the inside of the end of the battery tube is conical and the tail-cap contacts are pushed into the cone as you tighten the tail-cap. This means it is far less likely to break the connection, as the tail-cap needs to move significantly to lose contact. It makes the connection very robust, but does prevent the user from locking-out the M23 by unscrewing the tail-cap.

The pocket clip is very strong, a bit too strong for normal use. If this is going on your load carrier PALS webbing, OK, but for many users it will probably be too stiff.

Of course we must appreciate that JAVELOT beam. The custom XP-L Hi LED certainly does its job with plenty of power and an excellent hotspot. Unlike completely throw-orientated lights, the M23 manages a high beam strength without making the hotspot too small; it seems completely ideal for a light this size.

Normally I’m not keen on using lights with throw at close ranges, but the M23 seems to manage this in a way that is perfectly usable. However as a frosted glass diffuser is supplied, you can easily go full flood (at the expense of 33% loss of output) and have a perfect indoor flood-light beam. With the diffuser fitted it will not fit into the holster.

It is possible to tailstand the M23 even though the large switch boot (18mm) protrudes slightly. The combination of three large cut-outs around the button (giving easy access), and the large button itself make the M23 responsive and reliable to control.

The user interface seems extremely well suited to a ‘tactical’ design. Putting strobe to one side (all serious users of tactical lights I’ve spoken to don’t want strobe as it can be just as disorienting to the person using it), at least it needs a deliberate triple-click to activate it. Unfortunately, if you are ‘signalling’ with the M23 you can accidentally get strobe. Taking just those constant modes, you can easily set the M23 to be effectively a ‘high only’ light or a ‘low-high’ light. Setting high with the twisty interface means that your first press is always high, and if you double-tap the button you still have high. Setting low with the twisty interface means that your first press is always low, and if you double-tap the button you get high. Swapping between these configurations is easy and of course you could also make it ‘medium-high’ as well.

Overall a well thought-out light with solid build and a great beam; another JAVELOT success.

Light Review: NITECORE EA45S

7 June, 2016

NITECORE’s first die-cast unibody light was the revolutionary EC4 (check the index page for a review link). Developing the idea further, we now have a 4xAA thrower using a similar format die-cast ‘unibody’, the EA45S.

Taking a more detailed look:

NITECORE’s familiar cardboard packaging is used.

Inside the box is the EA45S, a wrist lanyard, holster and instructions.

Holsters are always appreciated and this is well made.

You have the choice of a fixed belt loop, Velcro belt loop and a D-ring.

A very distinct feature is the red tail-cap screw that the ‘S’ versions of the die-cast lights have.

There is a dual side-switch for operating the EA45S.

Heat sink fins are cast into the body. Thanks to the die-cast body there is an uninterrupted heat-path from these fins (and the rest of the body) to the LED board mount.

At the base of a smooth reflector is the EA45S’s XP-L Hi V3 LED.

Looking more closely at the XP-L Hi V3 LED.

NITECORE’s die-cast lights use an unusual tail-cap design. It has lugs to engage with the body, the contact board, and a thumbscrew.

Looking slightly left of centre in this photo, you can see the threads which are almost entirely hidden.

Those threads engage with a small section of threading inside the body.

Here you can see the EA45S next to the four AAs it holds.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

Designed for throw, the EA45S has a very defined and strong hotspot.

Giving it a bit more range to work with, you can clearly see the power of the beam which is very impressive considering its 4xAA power source.

Modes and User Interface:

The EA45S has a total of five constant modes (Turbo, High, Medium, Low, Ultra-Low) and three flashing modes (Strobe, Beacon and SOS). Like many other NITECORE lights this is controlled by a dual button.

From OFF, to switch ON to the last used steady white output, briefly press the Power switch. When ON, press the Mode switch to cycle through Turbo -> Ultra-Low -> Low -> Mid -> High back to Turbo etc. To switch OFF briefly press the Power switch.

From OFF, for direct access to Ultra-Low, press and hold the Power switch for more than 1s.

From OFF, for direct access to Turbo, press and hold the Mode switch for more than 1s.

To access White flashing modes, from ON, press and hold the Mode switch for more than 1s. This will activate strobe. Press and hold the Mode switch for more than 1s again to switch to Beacon mode. Press and hold the Mode switch for more than 1s once more to activate SOS.
Once activated, pressing the mode switch briefly returns the EA45S to the previous steady mode, or a brief press of the Power switch will turn the EA45S OFF.

There is a ‘Standby’ mode which uses brief low power flashes of the blue switch indicator LED to act as a locator to allow you to find the EA45S in complete darkness. To activate Standby, from ON press and hold the power switch for over 1s until the blue switch light comes on. Although low power, the flashes are bright enough to disturb someone’s sleep. Exiting standby mode is achieved by switching on the EC4. When using Standby mode the drain is increased but the should still last a year in this mode. Turn ON and OFF again to exit standby.

There is a lockout mode included. With the EA45S ON, press and hold both buttons simultaneously for 1s to enter lockout. When entering Lockout, the EA45S will turn off and give a brief flash of the main beam as you release the buttons. Like this the buttons will not turn the EA45S on. Thanks to the button design this can be done easily with the thumb. To exit Lockout press and hold both buttons simultaneously for 1s and the EA45S will turn ON in the last used mode.

Lastly when first inserting cell/s into the EA45S or briefly pressing the mode switch when OFF, the blue switch light will flash to indicate the battery charge level. It flashes once, twice, or three times. Three flashes indicates full power.

Batteries and output:

The EA45S runs on 4xAA, Alkaline or NiMh. NiMh will give the best performance.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

___________________________________________	________________________________	________________________________
NITECORE EA45S using Eneloop AA	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
Turbo	912	0
High	476	0
Medium	238	0
Low	63	0
Ultra-Low	2	0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity measured 43100 lx @1m giving a beam range of 415 m.

There is parasitic drain at 102.6uA (2.33 years to drain the cells).

The EA45S does indeed hit 1000lm at switch on, but this drops to a still impressive 912 ANSI lumens. The output gradually declines to around 800lm approximately 7 minutes after switch on, and then remains steady for the remainder of the runtime (just dropping to 750lm) before trailing off sharply once the cells are depleted.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

However, I did have a couple of issues with the tail-cap threads not engaging properly. It requires a very firm pressure during the entire fitting of the tail-cap to fit smoothly. The thumb wheel has a convenient smooth depression which allows you to press onto it firmly with your finger while turning the screw.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The EA45S in use

For those that have followed my reviews for a while, you will most likely know I have always loved the 2xAA format for being easy and comfortable to hold. I’ve tested other 4xAA lights which have had the four cells all together (making quite a handful) or 2×2 as in the EA45S. Thanks to the die-cast unibody and lack of cell holder, the EA45S takes this 4xAA format and fits it into a more compact body.

The EA45S has just pushed out the 2xAA as my favourite size/shape, and put itself firmly into pole position with its compact 2×2 4xAA cell layout. It is really comfortable to hold, stable, thanks to the rectangular cross section, and just the right size and weight.

This is a bigger light than I would EDC, but when I need a step up in performance and runtime without going to something really large, the EA45S fits the bill (and hand) nicely. It is also perfectly reasonable to just throw into a backpack even if you might not need it.

Of course with its throw biased beam, it can be a little fatiguing to use indoors. The Ultra-Low and Low modes are really all you will want to use when inside. Other than that the EA45S’s beam comes into its own. Peering into an engine bay, or deep into storage (loft, or other large space), the throw helps you to see clearly. Outside you can really appreciate the throw the XP-L Hi V3 LED gives you, and how comfortable it is to hold (I might have mentioned that before).

The surface finish on the EA45S is HAIII hard anodised, which can prove challenging on die-cast aluminium, but NITECORE have achieved an excellent quality finish. At first this surface might appear to be a powder-coat due to the graininess, but this is due to having to pre-treat (sand-blast) the die-cast surface before anodising.

A couple of other observations, there is a degree of cell rattle when you knock the EA45S or put it down, but this does not happen with normal handling. Also for use wearing gloves the switches can be a little tricky to hit just right.

Certainly in the sample I have, you have to be careful fitting the tail-cap. Removing it presents no issues, but due to the contact spring strength, it does need constant pressure on it to ensure the threads start and run properly all through the tightening. The thumb-wheel has a shallow smooth depression which makes it easy to apply pressure and turn the wheel to tighten it.

Thanks to the unibody design, heat transfer is managed with ease; nothing gets particularly hot with the entire body acting as a heat-sink.

There are other 4xAA lights with similar output, but NITECORE have delivered it with a superbly ergonomic design. I liked the EC4, but really love the EA45S.

Light Review: Olight S1 plus Special Edition S1 Ti

1 June, 2016

Olight’s S1 is the smallest light they have ever produced with a side switch. Along with the standard aluminium edition, Olight have created quite a storm of interest by also releasing several different Special Editions with different emitters and materials such as Copper, Titanium as well as Gold-plated versions.

Taking a more detailed look at the S1 (standard Al edition):

Olight’s standard plastic box packaging displays the S1 nicely.

Inside the box is the S1, a CR123 cell, spare O-ring (which is actually used to hold the S1 in place) and a wrist lanyard. A really thoughtful feature is that the lanyard comes with a threading wire fitted to it to make it easy to fit to the S1.

The S1 itself has a stylish two tone appearance with the bezel and switch rings in blue.

Keeping the size down, the tailcap is a very streamlined design. The spring clips into a slot and is used to hold the magnet in place. This makes it easy for the user to remove and replace the magnet.

The threads are square cut and as the body is short, there are not many actual threads.

Peering inside there is another spring terminal and an anti-rattle closed-cell foam pad.

Looking dead-on, the S1 has a TIR optic and the actual LED cannot be seen.

In a less common format, the cell is inserted negative towards the head and this is clearly marked on the side of the S1.

Just to give an idea of how compact this light is, here it is next to the already small Olight S10R (another RCR123 light).

Also for scale here it is in my hand (I take XL gloves)

Before moving on to the Special Edition another quick look at those lovely blue PVD trims.

Taking a more detailed look at the S1 Special/Ti edition:

In keeping with its Special Edition status, the Ti S1 gets a different box.

Presentation is excellent.

Inside the box is the S1, a CR123 cell, diffuser, instructions and a wrist lanyard. A really thoughtful feature is that the lanyard comes with a threading wire fitted to it to make it easy to fit to the S1.

A glorious looking light.

The clip is removable and reversible.

Construction of the tailcap is the same as the standard version with the terminal spring clipped into a groove and used to secure the magnet.

Square threads are used.

Looking inside the internals are the same as the standard version.

A Rose Gold plated bezel surrounds the TIR optic.

Without the diffuser fitted.

With the diffuser fitted.

For the special editions they have the identifier ‘Ti’ and a serial number engraved on the tail-cap.

Small, Shiny and Ti, a winning combination.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

Starting indoors with the Standard S1. The wide hotspot transitions into a wide spill giving a great all round beam, and one that works really well for EDC tasks.

The main difference in the Special Ti Edition is that the LED is neutral white.

Fitting the Ti Edition’s diffuser makes a hug difference giving a real lantern like beam.

The Diffuser itself is GITD as can be seen here once the test was over.

Outdoors, the wide hotspot does well enough up to medium distances.

The neutral emitter of the Ti does make the colours appear more natural.

Just to show what happens when the diffuser is fitted – GLARE – lots of glare. On the indoor shot the clamp prevented the glare from hitting the camera, but here it does not. Use the diffuser with caution.

Modes and User Interface:

The S1 has five output modes, High, Medium, Low, Moonlight and Strobe and a single click-switch on the side.

Basic ON/OFF operation is carried out with a single click of the side switch. The S1 will turn on to the last used standard mode (this does not include Moonlight or Strobe).

To change the brightness, while ON, press and hold the switch to cycle through Medium -> High -> Low -> Medium etc. Release the switch once you have the required output.

There are a few special functions:
Moonlight mode – from OFF, press and hold the switch for 1s until the Moon mode is activated.
Direct access to High – from OFF, double-click the switch.
Strobe – From ON, triple-click the switch.
Timer – From ON, double-click the side switch. The S1 will blink one or two times. Once means the 3 minute timer is activated, twice means the 9 minute timer is activated. To swap between 3 and 9 minutes timers, double-click the switch.

Timer mode means that the S1 will turn itself off after the specified time, and this can be started from any mode (including Strobe and Moonlight).

Batteries and output:

The S1 runs on either CR123 or RCR123.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

___________________________________________	________________________________	________________________________
‘Model’ and ‘Mode’ using specified cell	I.S. measured ANSI output Lumens	PWM frequency or Strobe frequency (Hz)
___________________________________________	________________________________	________________________________
S1 Al – High – CR123	428	0
S1 Al – Medium – CR123	92	0
S1 Al – Low – CR123	15	0
S1 Al – Moon – CR123	Below Threshold	0
S1 Al – High – RCR123	555	0
S1 Al – Medium – RCR123	92	0
S1 Al – Low – RCR123	15	0
S1 Al – Moon – RCR123	Below Threshold	0
S1 Ti – High – CR123	461	0
S1 Ti – Medium – CR123	92	0
S1 Ti – Low – CR123	12	0
S1 Ti – Moon – CR123	Below Threshold	0
S1 Ti – High – RCR123	541	0
S1 Ti – Medium – RCR123	91	0
S1 Ti – Low – RCR123	12	0
S1 Ti – Moon – RCR123	Below Threshold	0

* Beacon and Strobe output measurements are only estimates as the brief flashes make it difficult to capture the actual output value.

Peak Beam intensity of the S1 Al measured 3500 lx @1m giving a beam range of 118 m.
Peak Beam intensity of the S1 Ti measured 3000 lx @1m giving a beam range of 110 m.

There is parasitic drain but it is very low. For both the S1 Al and Ti, the drain was 1.1uA (145 years to drain a CR123 cell)

The trace here shows each of the S1 versions running on CR123 and on RCR123. The most distinctive difference is that on RCR123 the initial output is up to 120lm higher than on CR123. Once the light has been running for 3 minutes and the output ramps down to around 300lm, all four traces pretty much overlap. For the RCR123s, there is a sudden shut-off when the cell-protection kicks in. On CR123 the output starts to drop out of regulation at around 50 minutes after turn-on which is approximately halfway through the total ANSI runtime.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The Olight S1 in use

In reality there is little difference between these two versions in terms of practicality, except perhaps the neutral emitter in the Ti version. Of course the Ti version feels much more special and looks the part, as do any of the S1 special editions.

Regardless of special edition or not, the S1 is an excellent EDC light and won me round straight away. Easy and reliable access to Moon mode, direct access to High and memory of the last standard mode used, all tick the EDC boxes; all this and never forget its super compact size which makes it very easy to carry.

The built in timer is great for giving the light a ‘sleep’ mode so if you are camping or otherwise in need of a period of ‘settling-in’ before going to sleep, but not wanting to then have to turn a light off; it will turn itself off for you. Think of your own uses for this; I really like it even if I don’t use the timer all that much.

Being able to pop out the tailcap spring and remove the magnet is a really clever design. Magnets are useful, but very often I get annoyed with them picking up this and that. Now I can choose to have the magnet or not.

Deciding between CR123 and RCR123 will be personal preference. For heavy users the guilt-free-lumens of RCR123 may be a better match, but check that runtime graph; a sudden cut-off might be a problem for some users. If it is a problem, stick to CR123, as for general light EDC use it will last a long time.

Thanks to the very low parasitic drain, you can be confident that leaving it loaded up with a CR123, the S1 will be ready to go when you need it, and you won’t find it with a run-down cell. If you are super-paranoid, you can lock out the Standard version by unscrewing the tail-cap half a turn. You cannot lockout the Ti Special Edition like this as the threads are not coated.

Although a TIR lens was chosen for better control of the beam shape, it has the added benefit of being pretty much unbreakable. That beam is a general purpose beam which is well suited to closer range typical EDC uses.

Even though I’m use to it, I still have to think twice when putting a new cell in, the ‘negative terminal towards the head’ layout seems a strange choice when convention has the positive terminal towards the head. It does include all the relevant protection in case you get it wrong, but this seems an unnecessary unconventional touch.

The switch is quite low profile and without the clip often needs a bit of ‘hunting’ to find. The clip, which seems relatively large, can act as a guide for finding the button, and also helps stabilise the grip. The S1 is small enough that is can feel insecure to hold, especially when performing multi-clicks of the switch; the clip gives a little something extra to get hold of.

Small, good looking and full of useful modes that are easy to get at. It is no wonder the S1 is proving very popular.

Light Review: NITECORE Headlamps – T-360, HA20 and HC30

13 May, 2016

With the launch of three new headlamps from NITECORE, the T-360, HA20 and HC30, I’ve had the opportunity to compare them. Each one is very different and fits a different requirement. Have a look and see which one would be right for you.

Taking a more detailed look at the T-360:

Before diving into the detail here are the three boxed lights together.

For the T-360, as it has a built-in USB rechargeable cell, there is simply the T-360, a headband and the instructions in the box.

Giving it its unique versatility, the T-360 has a ball joint around which the entire light head swivels and rotates.

Just slipping in a gratuitous shot of several T-360s lined up.

Being so small and light, you can keep a spare one on the same headband!

Shown here in its head-mounted configuration with the spare T-360 as well.

Taking a more detailed look at the HA20:

For the HA20, as well as the light unit, there is the headband (with top strap) a special square-shaped O-ring and the instructions.

Fitting the strap is very easy.

You can’t get to the battery compartment with the light unit rotated normally.

First you need to rotate the unit forwards to expose the plastic tab.

Then you can pop the cover open.

Finally you can rotate the light unit all the way back round to allow the door to come off.

Each end of the battery compartment has a set of sturdy terminals.

You have to fit the rear cell first then the front one.

The HA20 has three LEDs, an XP-G2 LED and two F5 red LEDs.

A closer look at the main beam XP-G2 and its reflector.

The elastic strap for the main headband is routed through the mount as shown.

The top strap gives extra stability when wearing the headlamp.

Taking a more detailed look at the HC30:

Of these three headlamps, the HC30 has more accessories as it includes two spare O-rings, a spare switch boot and clip as well as the HC30 itself, headband and instructions.

A very sleek design.

On the head of the HC30 is a low profile rubber click switch.

When looking side on you can see the deeply cut heat-sink fins.

The battery tube cap has been laser engraved with NITECORE’s logo.

Inside the tail-cap is a spring contact which has been tucked into a groove, removing the need for any circuit board and allowing the depth of the cap to be as shallow as possible.

The threads are Acme (trapezoid) in form, well lubricated and fully anodised (allowing lockout).

Inside the battery tube you can see the physical reverse polarity protection (also requiring the use of button top cells).

Thanks to a well thought-out design, the HC30 is not much larger than the cell it uses. A very nice compact design.

An XM-L2 LED is used.

For such a compact design, the reflector is relatively deep.

You can fit the optional clip into either groove giving an up or down position. With the clip fitted it does not fit into the headband mount properly.

With the strap sitting against your head, and the mount being low profile, you have maximum comfort.

The fully assembled headlight.

On the head, the HC30 is very comfortable, light and stable.

The LED on the Ultra Low mode showing the dots on the phosphor surface – just because…

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

Being a comparison review, we have the opportunity for some side-by-side (or top-to-bottom) comparisons using the same exposures. However BEFORE we start that comparison, as the T-360 is a tiny lightweight low powered light, to just get an idea of the beam, this first photo is at an exposure to give the best impression of the beam.

Now we start the comparison and the exposure has been set for the HA20 and HC30 to show correctly so the T-360 appears rather dim in comparison.

On the same exposure, the HA20 – there is a very defined hot-spot and a wide smooth spill.

Again on the same exposure, the HC30 shows its power. It has a broad hot-spot and bright spill, but the spill is narrower than the HA20.

For the outdoor beamshots, the T-360 did not have enough power to show, so is not included.
As before the exposure has been fixed to allow the HA20 and HC30 to be directly compared. Starting here with the HA20. The purpose of it hot-spot becomes clear as the lower power of the HA20 needs this to extend the range.

The HC30, of course, has much more power and this is very clear in this direct comparison.

Modes and User Interface:

Three different headlamps, and three very different interfaces.

UI: From OFF press the switch to turn directly ON to Lower mode (regardless of the previously used mode).
From OFF, press-and-hold the switch for over 1s to turn ON to ‘Last used constant mode’.
From OFF, press-and-hold the switch for over 2s to turn ON to Turbo.
While ON press the switch briefly to cycle through Lower, Low, Mid, High, Turbo, Lower etc.
To turn OFF press-and-hold the switch for over 1s.
From OFF, double-click the switch to enter Strobe. While ON Strobe, press the switch briefly to cycle through SOS, Location Beacon, Strobe etc. To turn OFF, press-and-hold the switch for over 1s.

Batteries and output:

The T-360 runs on its built-in cell.
The HA20 runs on 2xAA (Alkaline, NiMh or L91).
The HC30 runs on 1×18650 (button top), 2xCR123 or 2xRCR123.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

HC30/Medium – 18650	245	0
HC30/Low – 18650	82	0
HC30/Ultra Low – 18650	2	0

Peak Beam intensity for the T-360 was not measured.
Peak Beam intensity for the HA20 measured 2800 lx @1m giving a beam range of 106 m.
Peak Beam intensity for the HC30 measured 6800 lx @1m giving a beam range of 165 m.

There is parasitic drain in the T-360 but this was not measured due to the built-in cell.
There is parasitic drain in the HA20; the drain was 194uA (1.23 years to drain the cells).
There is parasitic drain in the HC30; the drain was 51.5uA (6.87 years to drain the cell).

All shown on the same graph, the performance of each of these light is very different on maximum output.
The T-360 is very consistent for 30 minutes and then tails off to the point of being no use by 45 minutes.
The HA20 drops from maximum after around 10 minutes, and after stabilising again, remains consistent up to the last part of the run.
The HC30 however, has a strange behaviour which is only really noticeable using measuring equipment. After the initial drop after 5-6 minutes, the output rises, stabilises, then rises again before starting a gradual decline. Having a wide input voltage range from 3V to 8.4V, this will be a consequence of having to manage the quite different cell characteristics. Remember this is the maximum output, so it is testing the limits of the cell as well as the HC30. To the naked eye this behaviour doesn’t stand out.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The T-360, HA20 and HC30 in use

Do I have a favourite? Yes, but more on that later, as each of these headlamps gives you different benefits and capabilities.
—–
You are probably familiar with the NITECORE TUBE key-chain light. The T-360 is a spin off of this USB rechargeable featherweight light and gives you a featherweight headlamp. As I showed earlier it is so lightweight you can install two (or even three) on the same headband so you have hot-spares ready for when the cell becomes depleted. The T-360 means anyone can EDC a headlamp. Of course it is not just a headlamp as when you take it off the strap it will stand by itself, or can be clipped over a cap peak or pocket edge. Unlike the TUBE, the T-360 does not use any PWM so is superbly good to use on any level.

As shown in the head mounted photo, I have found the T-360 benefits from rotating the body out, so that it sticks out, when you use it. With the full flood beam, if you leave it flat on your forehead, half the light just goes upwards, so by rotating it as shown you can direct this down and make better us of the available light.
—–
Moving up in size and in power to the HA20. AA power is a significant benefit simply due to the ease of getting AA cells; this is not to be underestimated. This also makes it easier to give as a gift. With the HA20 there is a bit of a trade off in providing one of the features. The head has a really good range of adjustment, including upwards; The result of this is that the HA20 has been placed further from the head to provide the space to be able to rotate so far in the mount. With an aluminium body, this creates a slightly front-heavy design making the HA20 feel heavier on the head than it really is. Once you start moving about more it can become noticeable.

Still on the HA20, the two-stage button has proven to be a little difficult to work with. The half-press is somewhat indistinct so you are not entirely sure you have pressed it enough. The full-press is a substantial press needing the button to be pushed well into the switch boot.

Having Red light as an option in the same headlamp is one of the strong points. When I’m out hunting and using red light on the gun-light, the last thing I want is to then switch on a white light, so the pure red light (not filtered) is just what is needed. Just be aware that this is not ‘Star Party’ friendly red light as it is quite bright.
—–
Finally we have the bright and compact HC30. NITECORE have done really well in keeping the size down, and the HC30 is not much bigger than the 18650 it uses. A single 18650 is a great compromise for a headlamp as it typically has the energy of 3-4 AAs but weighs roughly the same as 2xAA(NiMh) cells and is a single cylinder (so more compact). This allows for greater output or longer runtimes from a smaller lighter headlamp. So as long as you are into li-ions (or happy to burn through CR123s), then it makes an ideal choice.

Even though it has only a single-stage button, the interface is very well thought out. With no delay at all you can click onto ‘Lower’, then cycle up to a level you want. Alternatively you can return straight to a previously used level if you are happy to press-and-hold for 1s. You also still have direct access to Turbo with a slightly longer press-and-hold of 2s. But there is more, as if you are into your flashing modes, a double-click brings them to life.

With all the modes available, I couldn’t have asked for more from this single button interface.

Comfort is top notch as the weight is kept close to your head (increasing stability) and the mount doesn’t touch you at all and has no hard/hot-spots.

For my own uses, I would have preferred a more flood orientated beam, but with its mixed use as a right-angle light and a headlamp the beam’s mix of flood and throw is very good.
—–
So could you spot my favourite? The HC30 has it, if I had to pick one.

Which would you pick?

Light Review: ACEBEAM H10 Headlamp

11 May, 2016

The H10 is ACEBEAM’s most powerful Headlamp with an impressive 2000lm burst mode (using an IMR 18650) and uses the high power MT-G2 LED array.

Taking a more detailed look:

Presentation is good with the ACEBEAM packaging. The box is sealed with a tamper evident tape.

Inside there is a foam liner holding the contents in place.

In the box there is the H10 (with unlabelled 18650 inside it), spare O-rings, pocket clip, headband and mount, plus the instructions.

The headband is fully assembled and opens out like this.

The headband mount has two retaining rings that line up with grooves in the body of the H10.

Looking at the back of the H10 you can see the shallow heat sink fins on the head, and the domed switch on top.

Surrounding the domed switch button is a rotating selector ring.

On the battery tube cap, the make, model and serial number are engraved.

As we will see further on, there is parasitic drain, so for transit (and to prevent accidental activation) as the supplied 18650 is fitted inside the H10, an insulating disc is included to break the circuit and lock-out the H10. You need to discard that white plastic disc to use the H10.

Inside the tail-cap the negative terminal is a spring. The top edge of the battery tube makes contact with the gold ring-terminal on the circuit board.

Peering inside the battery tube there is a simple positive terminal surrounded by a plastic insulator.

The threads are almost square, perfectly cut, fully anodised and well lubricated.

With a large MT-G2 LED the reflector is relatively small and is textured to further smooth the beam.

Looking straight at the MT-G2 LED.

Of course the H10 can be used as a right-angle light, but it is intended as a headlamp. Here it is fitted in the headband mount.

At the back, the top strap fits into the headband adjustment loop to help keep it centred.

Though the mount is a soft rubber, the strap is threaded through the mount to keep the elastic strap itself against the user’s head. This provides maximum comfort.

Some of the detail in the rubber mount’s moulding.

A pocket clip is provided for when the H10 is used out of the headband mount. It clips into either one of the grooves that are used for the headband mount. You cannot leave the clip on and fit it back into the headband mount properly. The clip is stiff to fit and has already marked the anodising.

The beam

Please be careful not to judge tint based on images you see on a computer screen. Unless properly calibrated, the screen itself will change the perceived tint.

For most purposes, a headlamp benefits from a flood beam, as it is generally used as task light. The H10, with its large LED and small reflector doesn’t disappoint, with a wide and even flood beam.

Moving outdoors, this headlamp does have enough power to give it some range despite the flood beam and the area is evenly lit.

Modes and User Interface:

The H10 has a two-stage domed button switch, and surrounding this a selector ring. The selector ring has four tactile stops for the four normal modes (1000lm, 500lm, 200lm, 30lm).

At any time (either from OFF or from any normal mode) a full press of the button gives you the maximum output 2000 lm Burst mode. When the button is released, the H10 returns to the previous state (either from OFF or any normal mode).

To turn onto a normal mode, half-press the button and hold for 2s. The H10 will then come onto the mode set by the selector ring. The mode can be pre-selected before turning on, or selected once the H10 is on.
To turn OFF, half-press the button and hold for 2s.

Batteries and output:

The runs on a supplied LG18650HE2 20A 2500mAh IMR 18650 cell, but can use any button top 18650 or 2xCR123, both of which will limit the maximum output.

To measure actual output, I built an integrating sphere. See here for more detail. The sensor registers visible light only (so Infra-Red and Ultra-Violet will not be measured).

Peak Beam intensity measured 6800 lx @1m giving a beam range of 165 m.

There is parasitic drain at and average of approximately 62uA (it varies between 32 and 93uA) which would mean a fully charged 2500mAh cell will take 4.6 years to drain.

Due to the extreme nature of the 2000lm Burst mode and the requirement to keep the button pressed, the runtime was not measured for this output level. Instead the runtime was for the highest constant output level the 1000lm high mode. This 1000lm output is well regulated for as long as the cell can maintain it; a very good performance.

Troubleshooting

This section is included to mention any minor niggles I come across during testing, in case the information helps anyone else.

No issues were encountered during testing.

As per the description of this section, this information is provided in case anyone else finds a similar ‘issue’ that might be fixed in the same way.

The ACEBEAM H10 in use

Two highlights of the H10 are its lovely smooth flood beam and the neutral/warm tint of the MT-G2 LED. These features allow you to focus entirely on the task you are doing and not even think about the headlamp.

A single 18650 makes for a comfortable weight to have head mounted, and thanks to the use of a top-strap as well, you don’t need to have the headband very tight for it to stay securely in place. A top-strap really does improve comfort. With the strap routed through the mount so that it is the strap itself that is against your forehead, again comfort is very good.

What I don’t like are interfaces that make you wait for the light to come on or go off, and unfortunately, the H10 requires a half-press, wait, and 2s later the light comes on (with the same for off). If you fully press the button by mistake you get the full 2000lm burst output, which is not a nice surprise, and you have to try again to get the H10 to come on. For every day use, I’d much prefer the on/off to be controlled by a simple click, and the burst to require a longer hold, but perhaps only 1s before it activates.

With gloves on, or with cold hands, I found the half-press unreliable, or at least my ability to find the half-press position. 2000lm when you wanted 30lm is not good.
Still, that beam is worth the wait when you are not rushing to do anything, and once on and running, the H10 melts away and you just have light.

Depending on how many lights you use, you might also not hit the right mode first time. There are no marks on the selector ring to indicate which mode you have chosen. A few simple marks would make the pre-selection of modes so much easier. If this was your main light you would quickly learn the positions, and there is a stop at each end of the selections, so you can simply turn it all the way one way until it stops, then count the clicks back to the mode you want.

Parasitic drain is acceptable, but with fully anodised threads you can lock-out the H10 easily.

The optional clip can be fitted into either groove on the body to give up or down positioning. Fitting is very stiff and does mark the anodising, so depending on if this bothers you, you may choose to make it a dedicated right-angle light or leave it as a headlamp. Swapping between the two will scratch the H10.

The H10 gives its specified outputs effortlessly including the impressive 2000lm burst mode (as long as you use IMR), and has not had any issues with heat. In normal use and for indoor jobs, I find the 1000 lm output too high so use it on 500lm or below. When outdoors I have ramped up to the 1000 lm mode but the added airflow seems to cope with the extra heat easily.

The lowest mode is named ‘firefly’…I would not want to meet the firefly that provides 31 lm! that 31 lm output with the flood beam is a great mode, and one I use a lot, but I’d prefer it if there was a 1lm or lower mode as a true firefly level.
