Light Review: Fenix E03R, E28R and E35 V3.0

4 December, 2020

A set of three EDC type of lights from Fenix (see MyFenix in the UK). This is a review of the Fenix E03R, E28R and E35 v3.0 covering a range of power and capacity options. Of these, the E03R has been available for the longest, with the E28R being a recent release and the E35 updated to V3.0 and using the 21700 cell with huge 5000mAh capacity.

What is in the box?:

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 my wife won’t have one!

The beamshots are divided into two sets with the indoor and outdoor beams for a more direct comparison. In the indoor set the E03R is first shown with the red beam and then onto the E03R white followed by E28R and E35 V3.0. The same order (minus the red) is used for the outdoor beams.

Batteries and output:

This gallery shows the measured charging current for the E03R, the E28R built-in charging, and the USB-chargeable cell supplied with the E35.

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.

Parasitic drain of the E03R cannot be measured.

This gallery has two runtime graphs. the first shows all three lights together for the entire ANSI run, the second is just to show the first few minutes of the run.
The E35 is showing clear thermal regulation as it hovers around the 1800lm mark.

Troubleshooting

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

The E28R displays a slight flicker in the main beam once the cell has reached a low enough level that the red switch warning flash is shown. At this point the output is very low and the cell needs to be recharged. The output is still usable but the flicker noticeable. As long as the low battery warning is not displayed this does not happen.

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 E03R, E28R and E35 V3.0 in use

Firstly a look at the relative sizes of these three options. On its own, the E03R is almost too small and easy to drop, but is intended to be attached to something (keys, zipper etc) and once it is, it suddenly comes to life in ease of use. For the other two, Fenix has nicely created the E28R and E35 to be only slightly bigger than the cells they use to power them, so your choice is almost more about the size and capacity of cell you want to have.

The interfaces of all the lights is basically the same apart from the E03R having red light instead of strobe. Press and hold to turn on, tap to change mode and press and hold to turn off. The last used output is memorised apart from the E03R which always starts on low.
A little trick to get the E28R and E35 to start on low is to use the lockout feature (double tap when off, and then double tap again to unlock) as the lowest output is selected when coming out of lockout.
Personally I would prefer an option to allow a single click to turn on as the press and hold is less immediate when using it.
The switch is relatively low profile on all three models, and just by feel, can be tricky to find. The E03R can just be held in a pinch grip and even if the button is underneath it will operate. For the E20R and E35, I found the pocket clip essential for ‘indexing’ my grip and finding the power switch. The clip is free to rotate around the tube, so the alignment can be off if you are not careful. I do like a side switch for daily use.
Beam tint is nicely neutral to warm, with the TIR optics giving a easy to use beam.
When you have the convenience of the built-in USB charging port, the drag of having to unscrew the light to charge the battery (E35) becomes more apparent. Perhaps the E35 v4.0 will have the USB-C charging built into the head like the E28R? Of course this is balanced by the cell having a healthy 5000mAh capacity, so unless you are always blasting the highest output level you should have a good time between charges.
A little note on the E03R red beam. Typically you want to keep light levels low when using red, so it is a pity there is no direct to red option. However, this is easily worked-around by simply holding the front of the E03R against your hand/leg/whatever while holding the power button, and do this long enough to reach the red output before using it. As the majority of use is most likely white anyway, it is no real hardship to do this when red output is needed.

Light Review: Fenix TK30 White Laser LEP

4 October, 2020

LEP, what is LEP? Laser Excited Phosphor, the new super thrower with a highly focused beam; and I was certainly excited to try out the Fenix (see MyFenix in the UK) TK30 White LEP light. I first came across the concept of LEP to be used as a long range tactical scope illuminator for snipers, and there is no doubt this is a highly specialised type of light. For long range scope illumination it is outstanding, and for the general lighting enthusiast it is a lightsaber, with near laser beam like projection.

First up is a video which covers the basics of a look round the TK30 and some outdoor video to show the incredible beam. This page has a lot more detail including the measured output figures, runtime graph and photos of the beam.

What is in the box?:

A good look round the TK30 – Things to look out for here are:
The TK30 comes with an excellent belt holster, and a 21700 cell that has a built-in USB-C charging port (in the cell, not the TK30).

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 my wife won’t have one!

Yes, this really is the beam, not a mistake. There is a small bright spot with all 500lm (422lm measured) in it.

Batteries and output:

The runs on the included 5000mAh 21700 cell.

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.

Peak Beam intensity measured 469000lx @1m giving a beam range of 1370m!!!

In this gallery are measurements of the built-in USB-C charging for the 5000mAh cell, and the runtime graph (with active cooling).

Troubleshooting

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

It was noted that when the low battery warning is shown with the flashing indicator in the side switch, this makes the main beam output flicker. More on this is included in the ‘in use’ section below.

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 TK30 in use
Let’s first just get the minor quibble out of the way with the output that starts to flicker when the low battery warning comes on. It is shown in the marked copy of the runtime graph and only affects the very last part of the run. I personally take this as a point of the output being so near the end and not able to maintain the full output, that I would want to recharge the battery anyway at this point.

In some ways, the visible beam flickering is only further indication the battery is too low, so is not a problem so much as a ‘feature’. Moving on…

So the operation of the TK30 is just fine, a tail-switch, and a side switch for the mode. Easy and straightforward to use.

Although the high beam output is only in the region of 500lm, I would say that the heat generated and felt at the head of the TK30 is more than I would expect for a 500lm light. But this is no ordinary 500lm light. Inside the head is a UV Laser module that is then illuminating a phosphor surface to produce the beam, so overall it is not as efficient as a typical LED emitter and so generates more heat.

Swapping from the included 21700 cell to an 18650 (with adapter), the runtime is much less, and the lower efficiency of LEP to LED becomes even more obvious. A trade off in efficiency in exchange for a beam unlike any other.

Just take a look through this gallery. (I have used the Moon to cheat with a couple of these, it’s not quite that amazing.)

_______________________________________________
What doesn’t work so well for me
_______________________________________________
Not really a ‘con’, but a warning – this is a specialist light and is not suitable for general use due to the tiny hotspot and no spill.
Shorter runtime compared to an LED light.

_______________________________________________
Things I like
_______________________________________________
Super focused beam with 1370m throw!
LEP – Laser Excited Phosphor.
USB-C rechargeable 21700 cell and cable included.
Very good belt holster.
It’s just superb fun to have a lightsaber / white laser.

Light Review: Weltool 365nm UV/Red lights – M2-OL, M2-BF and M7-RD

13 September, 2020

For my first Weltool review I’m taking a look at some specialist lighting options; no white light here, instead it’s two lights with 365nm UV output, and one pure Red 625nm output. The models on test are the M2-OL (flood beam 365nm UV light kit with charger and cell), M2-BF (pure 365nm UV output, light only), and the M7-RD (625nm Red output with USB chargeable cell).

What is in the box?:
A quick overview of the three models and how they arrived. The M2-OL also includes a single-bay USB charger in the box.

A good look round all three of the models – Things to look out for here are:
The first one to be unpacked was the M2-OL. All three use a very similar chassis, with minor differences. For the two that included 18650 cells, each had an insulator disk to prevent accidental switch-on during transit. The lens/bezel arrangement is different in each of the three.

Taking a more detailed look at the charger and cells:
The M2-OL included a flat top 18650 with USB charger, and the M7-RD came with a USB rechargeable 18650 (no cell was included with the M2-BF). After looking over the set of contacts and the image of the flat top cell, you can also see a side shot of the cell in the charger where the negative contact end is raised slightly. This was required for the positive contact to touch the positive terminal in the charger.

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 my wife won’t have one!

In this set of beamshots, the only outdoor beamshot is of the M7-RD red beam, as the UV lights do not show up anything significant for this type of image. However, where it gets interesting is indoors. For this gallery, the first image is for the M2-OL, which is not pure UV, having some blue light. The next image is at the exact same exposure with the M2-BF that has a filtered output so it is pure 365nm UV light, and the only visible features are those fluorescing in the UV. The last two are of the red beam of the M7-RD.

Special beam galleries:
To properly appreciate the output of these dedicated UV lights the next two galleries are needed. In the first gallery are two sets of images, each set of the same scene, starting with a control image using a warm white light, then the M2-OL, and finally the M2-BF. The results are very clear.

In this second special gallery are two views from a pebble beach, where the confusion of the stones easily hides details that UV can reveal. In this gallery, a control warm white light is used, and the M2-BF. The last image shows bank note security features and the glow around the spots on a banana skin.

Batteries and output:

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.

Included here are two charging traces, first for the USB charger and 18650 cell that came with the M2-OL, and second for the USB chargeable 18650 that came with the M7-RD. Lastly is a runtime graph for the M7-RD (which should be showing the actual lumen output), and the M2-BF showing a simulated output. The integrating sphere sensor does NOT measure UV, so in this run for the M2-BF I included fluorescent material inside the sphere to convert some of the UV to visible light. Doing this allows for a ‘relative’ output trace over the full runtime, but is not a measurement of actual lumens.

Troubleshooting

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

As mentioned in the previous section “Taking a more detailed look at the charger and cells:” The flat-top cell supplied with the M2-OL would not charge in the supplied USB charger. This was because the plastic wrap on the cell left the positive terminal slightly recessed. To allow charging the negative end of the cell just needed to be raised slightly.

Not a big issue and easily rectified. I mention it here in case you find the same and need to use this simple fix.

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 M2-OL, M2-BF and M7-RD in use:

These are specialist lights, so really shine (pun intended) in specific situations. If you are an enthusiast in portable lighting, then you might not really ‘need’ these lights, but they will be great fun to add to your line up.
If you are in need of them for their special purposes, then you have some really strong performers to choose from. Before getting to the model-specific comments, a quick look at their sizes; I am slightly surprised there is so much variation when based on the same body and switch, but each of these three is a different length, and has been fine tuned to the LED and lens configuration. All three lights have two output levels selectable with a quick on-off-on via the forward-clicky tailcap switch; all three start on low if left off for 2s or more.

M7-RD RED: Weltool describe the M7-RD as a choice that won’t affect dark adapted eyes. For this I partly disagree; yes, red light does have less of an effect on your night vision, but the M7-RD is very bright, and will still affect your night vision. Use this at a star party (if that is your bag) and you will be shouted at. However, I find it particularly useful for hunting. The quarry I often target does not appear to react to pure red light, and this means I can use a good brightness red light to help me, instead of a super dim light where I’d struggle to see (especially when using a gun light that is much brighter).

M2-OL UV: After looking at the special beamshot galleries, the M2-OL, might seem a lesser choice for a UV light, but the mix of UV with some blue light has a place. It means that you have some ‘supporting’ light to see other features in the scene even if they don’t react to UV. This mix of light is helpful and gives a different view of the area.

M2-BF: This is the most specialist of the three, as there is a filter lens to remove all but the pure 365nm UV light. If there is nothing to fluoresce, you won’t see anything. In the photo below, the M2-BF is on, but apart from the glow of the paper surface in front of the lens, you might not know it was on at all.
With this super pure UV you can reveal hidden details, and often show things you might rather you hadn’t seen! The M2-BF is the ultimate in true ‘black light’ as long as you don’t need any visible light mixed in.

Light Review: The 10,000 lumen Fenix LR35R

6 July, 2020

Can it be true? 10,000 lumens from a light you could fit in your pocket? In this review of the Fenix LR35R I put Fenix’s claimed output figures to the test. As well as this companion review there is a full length video review, with behind the scenes insights into the testing. It turns out that this light went beyond the limits of my test equipment and meant making modifications to allow an accurate reading to be taken.

Here is the video review:

What is in the box?:
As this is a pre-production sample, there is no un-boxing as only the light was supplied.

A good look round the LR35R – Things to look out for here are:
Be sure to check the video for many of these details.

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.

I don’t actually have a ‘white wall’ in the house to use for this, and my wife won’t have one!

Batteries and output:

The LR35R runs on two 21700 cells which can be recharged in the light.

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.

Before getting onto the output graphs, let’s quickly look at the USB charging graphs. Fenix have use a pulse charging approach which the three images show clearly. Peak charging current is 3A.

And the three runtime graphs which show the effect of the thermal regulation, and how this is countered with stronger cooling.

A thermal image taken during the runtime testing.

The LR35R in use

A real surprise that this output can be achieved in a light smaller than one of my old favourites, the TK35. It does heat up very quickly, and in normal use, hand held, the thermal regulation kicks in much faster than on the runtime graphs which had strong cooling.
The built in charging is very useful, especially as all the 21700 rated chargers I have would not take the long Fenix 21700 cells. It also means you don’t need anything else, and can swap the cells if needed.
As the LR35R is so small, I really wish Fenix had added a lower sub-lumen mode, as for me that would make it a fantastic all-rounder.
Be aware that the headline 10,000 lumens is only short lived, but if you take it down a notch or two, the performance is very very strong.
Beam tint and beam profile are very useable, and overall this is a powerhouse that is easy to live with.

Light Review: Fenix HM65R Headlamp

21 May, 2020

With the HM65R, Fenix have fitted in so much, but have kept this headlamp small and light enough that you don’t have to think twice about taking it with you on any adventure (or even just taking out the rubbish).
The 18650 li-ion cell used to be the ‘enthusiast’s choice’, being unfamiliar to many users, even more so when strapped to your forehead – not any longer. The Fenix HM65R comes with a high capacity 3500mAh 18650 cell, and there is a built in USB-C charging port. The ONLY thing you need is a USB charger of some kind to open the door to this powerful and capable light.
Join me in this review of the Fenix HM65R to take a look at all the details and how it performs.

What is in the box?:
For maximum stability the HM65R has a top strap, and the full head strap comes assembled and neatly tucked away in the packaging.

A good look round the HM65R – Things to look out for here are:
I’m splitting this detailed set of photos into two galleries for a more manageable tour of the HM65R. The HM65R is almost ready to go out of the packaging, but first you need to remove a small insulator that keeps the battery from running down or the HM65R from being turned on accidentally. From the appearance of the threads of the battery tube, you can see that this is made of magnesium, a material chosen by Fenix to shave off a few more grams of weight.

Taking in more details:
First up in this gallery are the twin lenses – the larger spot emitter with clear lens, and the smaller flood emitter with honeycomb type diffuser lens.
For a more stable fit to your head, the inside of the front part of the headband strap has a grippy strip. Flipping the HM65R forwards gives access to the USB-C charging port and shows the angle adjustment mechanism.

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 my wife won’t have one!

For both indoor and outdoor beamshots, the individual spot and flood beams are shown, then (as both can be turned on at the same time) the combined beam. Each of the photos in the set of three is at the same exposure and white balance.

Batteries and output:

The HM65R runs on a supplied 3500mAh 18650 Fenix li-ion cell.

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.

Take note of the very good (low) parasitic drain measurement.

Also shown in this gallery is a charging graph for the built in USB-C charging. Although USB-C is capable of up to 3A, the HM65R seems to top-out at about 1.4A when charging.

The HM65R in use:

Straight off the bat, the HM65R makes itself a success with the stable and comfortable head strap (with top strap), and the choice of spot or flood beams (or both combined). Then, in using the high capacity 18650, you get a great runtime and powerful output (yet without too much weight), and the built in USB-C charging means you actually don’t need anything else – The HM65R is a complete kit.

There is one thing missing for me though, and that is a very low output. Even 9 lm, and even with this being on the flood beam, it is still too bright for dark adapted eyes. Frequently when I’m using headlamps, I will have dark adapted eyes (waking from sleep, or when I don’t want to disturb others); if only Fenix could squeeze in that lower mode, a sub 1 lm mode for both spot and flood output, it would make the HM65R a fantastic all-rounder.

If you want to go full blast, then your wish is the HM65R’s command – perfect visibility.

It is very helpful having the quick charge level gauge, with just a click letting you see if you will want to top up the battery.

Having used many Fenix headlamps over the years, and many competitors headlamps too, the HM65R definitely goes down as a choice for Pro users. I use the term ‘Pro’ to indicate this is a serious tool, capable of hard work, versatile and something worth investing in.

Light Review: Nextorch T53 Hunting Kit

29 March, 2020

NEXTORCH have been working on LED swapping lights for some time, lights that maintain full beam quality; the Dual-Light models were the first of these that I used (like the P5G, P5R etc.). This Light Review is for the T53 hunting light set, that not only has a LED swapping triple colour output mechanism, but also a mount and remote switch.
The crucial difference with NEXTORCH’s lights and their LED swapping mechanism being there is no compromise of the reflector or beam. Typically, multiple LED light have the LEDs set into fixed, off-centre, positions in the reflector, compromising the beam. Instead the T53’s chosen LED sits at the reflector’s focal point, and is completely swapped for another LED positioned exactly at the reflector’s focal point… keep reading for all the details.

What is in the box?:

A first look at what the T53 set includes, which is all well presented in the box. Everything you need to use it is included.

A good look round the T53 Set – Things to look out for here are:

The images take you through the major components and the details of each of these. Starting with the clamp-mount to hold the T53 in various positions on the gun of your choice. It uses a cam-lever to lock into place. The mount also has a couple of small rail mount section so you can add extra accessories. A nice remote switch has both latching and momentary buttons on it, plus hook/loop straps for fitting to the gun.
There is a small socket in the tail of the T53 which takes either the charging cable or remote switch. With the appropriate plug in place, it can be rotated to lock it in the socket.

Taking a more detailed look at the LED switching:

This is the magic of the T53 (and other NEXTORCH LED swapping lights). The LED at the focal point of the reflector can be completely swapped for another by rotating the dial on the side of the light’s head.

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 my wife won’t have one!

In this gallery all exposure settings for the set of indoor or outdoor shots are the same.

Batteries and output:

The T53 runs on a supplied 2600mAh 18650 cell.

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.

There is parasitic drain – this is included in the table of measurements.

Included in the gallery are the USB charging trace, a table of measured results, and the runtime trace for maximum white output (plus zoomed-in graph for the start).

The T53 Set in use

Let’s start with the T53 on its own. NEXTORCH lights always have a nice solid feel, and the T53 is built a little bigger to accommodate the LED swapping mechanism. Just as a single 18650 powered light, it is a little chunky and heavier than if it were only a single LED light. The tail-switch is not what I would term ‘tactical’ as it does not stand proud, making it a struggle to press far enough in to latch on if wearing gloves. This is not an issue at all in normal use, and certainly not a factor when moving to the remote switch.

Charging can be carried out internally using the supplied cable, and when doing so, in this example charged to a healthy 4.18V. Although not quite to 100% capacity, I much prefer this slight lower than 4.20V level as it is better for the life of the cell.

Before moving onto the gun mounting, a quick note on the tail-switch. This functions the same whether the remote switch is connected or not, in fact the two switches overlay their functions.
The tail-switch, if half-pressed, first turns on on high. If double-tapped you get strobe. However if you fully press to click it on, a subsequent half-press changes to low output.
The remote-switch, has a latching switch and a momentary switch. Either switch only gives access to high however many times you tap, you only get high.
Now, for example, if you had the tail-switch strobing, and then use the remote switch it changes to high, and once you turn the remote switch off it goes back to strobe. This is how they overlap each other.

In the next gallery the T53 is mounted onto a Chiappa Little Badger. More often than not, lights like the T53 are described as scope mounted. This is a personal bugbear as I dislike the way the spill light illuminates the gun and this creates a gap in the beam. So I will always, if possible, mount the light to the front of the gun to ensure none of the beam hits the gun. Here I’ve been able to fit the mount to the SAK sound moderator – it fitted, but was getting near the limit.

When fitting the mount, the design makes it very quick and simple to secure. The main adjustment is with the central screw and once snug, locking down the cam latch clamps it nice and tight.

Thanks to the hook/loop straps the remote switch fitted on easily, but larger stocks might prove too large for the straps.

The galley includes actual through-scope views.

For hunting use, I never looked back once I started using coloured lights, the difference is literally like night and day. There is also a massive difference between filters fitted to white lights, and pure colour LEDs, both in quality and brightness. I have no need to change colours on one outing as the gun is chosen for the quarry, and the colour to match the quarry. In theory I then don’t need the ability to change colour in one light. That said, it means the one light is suitable for all setups, and you won’t bring the wrong one.

Target illumination is very good with all colours, and something I found very useful was the ability to set the low output with the tail-switch and ramp it up to high as needed with the remote switch, then back to low again.

This is a very accomplished package from NEXTORCH.

Light Review: Surefire E2D Defender and Stiletto

16 February, 2020

With Surefire, your main expectations might be high quality build and performance, so read on to see if these lights keep up with Surefire’s standards. In this review are two quite different models; the latest update of the classic Defender E2D (in this case the two-mode ‘Ultra’) and the EDC-optimised pocket-friendly USB-chargeable multi-mode, programmable Stiletto.

What are we looking at?:

Though this review is all about the two headline lights, as well as primary cells I’ve been able to test the Surefire rechargeable cells for the Defender.

Moving onto the main feature let’s get into the details of these two.

Taking a more detailed look at the Stiletto:

The Stiletto is a new style of light, taking on more of the form of a pocket knife and slipping into your pocket in the same way, and with a clip to hold it in place. To achieve this narrow profile it has a built-in battery and USB charging, allowing the shape to not be compromised by replaceable batteries.

Taking a more detailed look at the Defender E2D Ultra:

The Defender E2D is a classic Surefire model, bit it has moved with the times. Starting life as a incandescent bulb light with lens/reflector, it has grown to use LED and TIR optics. This latest version has raised the output to 1000lm+. It is mainly the head of the light that has changed in appearance compared to the earlier models you might know.

Surefire’s rechargeable CR123 option:

Surefire have been a little behind other manufacturers with regard to taking up rechargeable batteries. In years past, dedicated Surefire owners have had to find their own way, often going to the lengths of getting their battery tubes bored out to take 18650 cells plus a few other methods.
In this case, the cells themselves are not Surefire branded, instead Surefire have chosen K2 Energy’s Lithium Phosphate cells.

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 my wife won’t have one!

The character of each beam is really very different. Starting with the Defender and it’s mix of smooth hot-spot and spill beam giving a very useful all-round capability. The spill beam is surprisingly wide, so much so you can see the bezel crenellation shaping in the outer edge of the beam.

The Stiletto has a Surefire ‘MaxVision beam’; I’ve come across a few variations of this, but in essence they have all been quite wide and evenly lit to give you ease of vision at close to mid ranges. You will notice in the direct comparison that the Defender’s beam is actually wider than the Stiletto’s. This is even more noticeable in the outdoor beam-shots. The Stiletto however lacks the hot-spot and provides nicely even lighting.

Batteries and 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).

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.

This is a table of measured results. PWM frequencies are recorded by an oscilloscope, and in some cases are clear and in others are more like superimposed noise. It only appeared that the Defender’s High beam when using the RCR123 cells showed any PWM. This is possibly due to power supply pulsing with the different voltage of the RCR123 cells which were able to produce a higher maximum output than on CR123.

In the runtime graphs, first check the start of the run and you can see how the RCR123 cells are capable of keeping that peak output from the Defender until the programmed slope-off of the output after 60s. However skip onto the full runtime and you can see the RCR123 cells run out after thirty minutes, but the CR123s go on a lot longer and with much more warning they are getting low. For ‘duty’ use you will still want to use CR123s, but the RCR123s give great guilt-free lumens.

Performance is solid from the Stiletto and output is more than good enough for EDC; 45 minutes of 500lm-plus output is impressive.

The Defender E2D Ultra and Stiletto in use

Though by no means a lesser light, there is perhaps slightly less to say about the Defender E2D, so I shall start with that. For me the ‘Ultra’ version is absolutely the one to have. The output levels are so opposite with a 9lm Low and a 1000lm+ High, these might seem too at odds to work well, but they do. If I could add one thing to the Defender E2D it would be a way to user program the Low to be the first mode, but without this the High-Low mode order ensures it lives up to its name.

Thanks to the beam shape and hot-spot, the 9lm mode does a great job for those daily needs of a bit of light. It hits the right balance of being low enough for complete darkness but not so low it is useless for anything but pitch black.

I have many 1000lm+ lights and many into the 5000lm+ level, yet the Defender seems to manage to appear brighter than similar output lights. I have never been left wanting by the Defender (running on the RCR123) with its solid performance and beam profile.

The slim body allows easy cigar gripping and general operation is what you expect from a tail-switch light.

And the Stiletto, this is a very different concept and is very different to use. It’s flat profile and large pocket clip make it one of the easiest lights I’ve used to pocket carry. Ergonomics are a really strong point with the Stiletto. In general use you will find the main side-switch falls nicely under your thumb. Side-switches are far superior to tail switches for EDC tasks, and make it more comfortable to hold the light for extended periods with a low arm position.

But of course, the Stiletto also has a tactical tail switch so you have the option of the high tactical grip with direct access to High. This leads me to the set of images in the gallery as I personally found the tail switch (which is quite stiff) gave me a few issues with grip and the Stiletto sliding forward. I had to use two methods to keep it stable; one was to hook my little finger just round the front of the aluminium head, and the other was to ensure I had the Stiletto rotated so I was gripping onto its width and not onto the flats. (check the gallery for examples) It has been fatiguing to use the tail-switch for longer periods, but with the streamlined shaping this is unavoidable.

The Stiletto’s main power switch is one of three areas on the rubber side panel; I am mentioning this to describe something else to be aware of. To the left of the main switch is a programming switch, this has not caused any issues in general use. However, the USB charging port cover is something to be aware of as I have often found myself trying to turn it on by pressing this part as it is quite ‘button-like’. It is very easy to do this, especially if wearing gloves, so just needs a little awareness and grip adjustment to correct.

‘Programming switch’ – yes the Stiletto can be programmed, with each switch independently programmed into one of two modes. I definitely prefer the default mode and I’d only change if I were mainly going to use the Stiletto in High. Programming is very easy – you hold the programming switch down until the indicator shows blue and then press either the main-switch or tail-switch to toggle it between modes. This programming switch also activates the emergency strobe.

Having three levels and the ability to swap the order from L-H or H-L is very useful. The most used mode for me was the Low, followed by Medium. High was too powerful for most of my EDC uses, but great to have for quick blasts.

The previous gallery has two in-use photos on a pathway to compare these two lights. In the earlier beam-shot gallery you could see the effect of the even circle of light the Stiletto emits. Once you get outdoors and don’t have light bouncing round to fill in the areas beyond the outer edge of the beam – the tunnel vision effect becomes more pronounced. You can see with both the Defender and Stiletto aimed in the same way, the Defender view is complete where the Stiletto’s beam leaves you blind beyond the narrower circle of the beam. Using the Stiletto in unlit areas required more beam movement and scanning to see where your feet are going.

Review Summary

The views expressed in this summary table are from the point of view of the reviewer’s personal use. I am not a member of the armed forces and cannot comment on its use beyond that covered in the review.

Something that might be a ‘pro’ for one user can be a ‘con’ for another, so the comments are categorised based on my requirements. You should consider all points and if they could be beneficial to you.

Light Review: Rovyvon A5, A8 and Angel Eyes E300S

11 October, 2019

Quite literally a ‘highlight’ from IWA 2019 are these lights from Rovyvon, so I was excited to get these on test and see what they could really do. In this review I’ll be comparing the Rovyvon A5 keychain light with two of the same size A8 variants, plus the E300S ‘Angel Eyes’, a larger but still EDC sized right-angle light. There is lots to see, especially with all the extra functions crammed into the A5 and A8 models!

I got this test group from Heinnie Haynes – if you don’t know this online shop you should do.

Taking a look at the A5 and A8:

The A5, and A8 models are all presented in the same way, so this is a quick look at the first one I unpacked.

More of the details of the A5 and A8 models.

Taking a look at the E300S Angel Eyes:

Unpacking the Rovyvon Angel Eyes.

The details of the Rovyvon Angel Eyes.

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 my wife won’t have one!

Here they all are, the different models, and different modes. Check the image caption for the notes.

Batteries and output:

These lights run on built-in cells.

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.

First up here are the A5 and A8 models and each measurable output. The value measured for UV will be a combination of visible blue light that is output or fluorescence of the test instrument and cannot be taken as a true UV measurement. ‘Max at Turn On’ is NOT an ANSI measurement, but a maximum value when switching on. (‘Below T’ means the output was below the threshold that could be measured.)

Then the E300S Angel Eyes. ‘Turn On’ is NOT an ANSI measurement, but a maximum value when switching on. Moon mode is not really 0lm, it is just below the threshold that could be measured.

Runtime and Charging Time:

In this gallery are charging traces recorded from a USB power monitor, plus the recorded output traces from an Integrating Sphere. Take your time here there is a lot of information.

The Rovyvon lights in use:

I’d had a good play with these lights at IWA, but there is still that frustration waiting for the first charge to complete – all blue – all good to go!

Before I go on, this photo summarises why these lights are so good, and that is their versatility. The A5 and A8 models are all multi colour, multi-function and super compact, and the E300S is very functional and powerful.

Staying on that line of thought, two of the models in this review have UV, and one is GITD. A small gallery to show these features in action.

The timing of this review means I have actually been carrying these daily for several months now. Electronic switches means there is always a chance that parasitic drain (standby circuit power) will deplete the battery, but there has been absolutely no sign of that.

One tiny light which has several functions, definitely makes itself very useful. UV is one of my favourite secondary functions for which I normally have to carry another light. Checking bank notes and looking for elusive little lost objects can be transformed with UV light. The extra colours of light available on the A5 and A8’s secondary side outputs all fit well with other needs; you being seen, marker lights, warnings, gentle night lighting or reading, the list goes on. What do you find most useful?

It is always challenging to design easy to use controls for multiple functions, especially with only a single button (or two with the E300S), and the Rovyvon lights use a variety of press-and-hold or multi-clicks. Depending on your current dexterity (which tends to vary when cold/tired/etc), you can easily get this wrong. The worst case result is getting maximum output when you didn’t want it. This is not a criticism of the Rovyvon lights, but only a consequence of the multi-function / single button interface.

However, with the A5/A8 and E300S there is a conflict in the user interface. To get the lowest level on the A5/A8 you double click, but the E300S requires a press-and-hold. So use the E300S, and when you pick up an A8, and press-and-hold expecting to moon mode, instead you get full blast. As these are both Rovyvon lights I would have hoped for some consistency in the UI across models to prevent this accidental blinding.

PWM (pulse width modulation – strobing the output to achieve lower levels) is a bugbear of mine. Any movement becomes flickery or stuttering. Unfortunately all the Rovyvon lights use this. The E300S uses a sufficiently high frequency that it does not present as a problem, but the A5 and A8, on all lower level outputs, have very obvious flickering whenever moving. If everything is static, then this isn’t visible, but if you are walking along or scanning a space you will see flickering. There are sometimes design limitations that force the use of PWM, as the circuitry needed for constant output tends to be larger, so the small size of these light might be the reason for this compromise. I hope Rovyvon find a way to get rid of the PWM (or at least increase the frequency) as these lights would be outstanding if they didn’t flicker.

Level spacing on the A5/A8 is good, but on the E300S there is much too large a step up from the lowest level to the next one, going from ~1lm to 70lm. It really needs a 5-10lm step.

With such high outputs available from a very small light, the overall runtime at these high levels is pretty low (A5/A8), so if you like using them on full blast, you’ll be recharging quite often, but if you mainly use the lower levels or side light functions, EDC use will be covered for a very reasonable time. USB recharging makes them very easy to top up.

The clear plastic bodies are light and strong with the added benefit of showing the neat internals. They have stood up to every day keychain use along with inevitable drops, bumps and rubbing against keys.

All the details are refined and functional with great clips, carry options and spares.

Light Review: Armytek Prime Pro – PART 3 – The Results

24 February, 2019

In ‘Part Three’ we get to see how these lights really perform, what the beams look like, their output figures and insights into what they are really like to use. – This is Part Three of a group review of four models of Armytek’s ‘Prime Pro’ range of lights (plus the Armytek Uni C2 charger). When embarking upon this review I had not expected to generate quite so much content, so have had to split the review into three parts to make it more manageable. You will find links to these as each part becomes available.

Index:

Each title here will become an active link once it has been published.
Part One – A Detailed look at the Prime Pro Magnet USB C1 and C2.
Part Two – A Detailed look at the Prime Pro A1, A2 and Uni C2 Charger.
Part Three – Beamshots, Technical Testing and What they are like to use.

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 my wife won’t have one!

There are a couple of key things to mention before you dive in and look at the beamshots. It is possible to make lights look very bright or very dim, regardless of their actual output, by adjusting exposure. So when you look at these don’t be swayed by the ‘apparent brightness’ instead concentrate on the beam quality. the intention is to show how the beam looks, not how bright it is. that is shown definitively in the next section.

This gallery also contains firefly comparison beamshots, and uses the original Predator V1.2 as a reference. These Prime Pro lights have Excellent firefly output.

Batteries and 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).

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.

The runtime graphs contain a lot of detail. One clear aspect of the control systems of these lights is that they maintain a constant output level as long as they can before stepping down to another level.

The gallery also contains the tables of output figures. Note that when I have ‘0’ for the output on firefly modes, this is actually below the threshold of measurement for the equipment I have and is clearly not actually 0. The Prime Pro A1 is measured with AA and 14500.

 

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

Charging results were a little bit unexpected for a couple of reasons. When checking the cells in the C1 and C2 after the included chargers indicated a full charge gave the following measurements:
C2 – 4.13V
C1 – 4.06V
Both seem low, but when checking these cells with a ZTS loading tester they both indicated 100% charge.
The C1 and C2 USB chargers are interchangeable so I tried them both on the C1.
With the charger that came with the C2, after a full charge the result was:
C1 – 4.15V
Using the Uni C2 charger the cells measured 4.16V once taken off the charger.

There is parasitic drain but is incredibly low in all models. The following list the drain in uA and how many years it would take to drain the cell(s).
Armytek Prime C1 Pro – 1×18350 – 2.8uA – 36.67 years
Armytek Prime C2 Pro – 1×18650 – 6.5uA – 56.16 years
Armytek Prime A1 Pro – 1xAA – 3.9uA – 55.58 years
Armytek Prime A1 Pro – 1×14500 – 3.8uA – 22.52 years
Armytek Prime A2 Pro – 2xAA 2S1P – 2.3uA – 94.24 years

The Prime Pro models in use:

I don’t want to come across biased, but I really do love these Armytek Prime Pro lights! If you give me a side-switch, choice of warm or cool output, no-PWM and properly-low firefly/moon modes, you will make me happy. So for these lights that is ‘check’, ‘check’, ‘check’, ‘check’ – bingo.

In terms of form-factor, AA lights have always been a favourite of mine. Now, with the NiMh cell becoming a preferred option for power (thanks to LSD cell technology, high output current, and inherent safety), with the added benefit of easy to find backup cells, the Prime Pro A1 and A2 become solid choices.

For that extra level of output power (thanks to li-ion power) and in-light charging convenience, the C1 and C2 step up.

To see how each of these compares in size, this is the full line-up together and then individual profile photos. Bear in mind for those individual shots that the head is the same diameter in each.

Normally I tend not to use the clips on lights, and often don’t fit them at all. All of these Prime Pro models seemed to be particularly ‘rolly’, wanting to find the lowest point of anywhere I put them down by rolling to it. So in this case, the clip has proven essential to stop them going wandering off and I’ve fitted it to all four lights. Although I am not particularly using the clip for clipping it to anything, as well as preventing them rolling, having the clip also provides indexing to make getting onto the switch quicker, and has been perfectly comfortable to have on the light. In this case I’d thoroughly recommend fitting the clip.

You can certainly get smaller EDC lights, but both the C1 and A1 are perfectly acceptable sizes to carry and not being too small, are comfortable and easy to use. For EDC, the C2 is pushing things a bit for me, and the A2 is for a larger bag. In terms of handling though, the A2 is a winner with the universally good handling 2xAA form-factor.

All these lights have an illuminated switch, and this illumination provides battery level information and a location function for the C1 and C2. For me the only time this switch illumination has slightly interfered is with the firefly modes. The instructions say the switch does not flash in firefly modes, but actually it does flash a couple of times when you first switch it on, and the flashes are about as bright as the firefly output itself. So when using these lights with dark adapted eyes, I find the need to keep the switch fully covered with my thumb for the first 10s or so until the switch flashes stop.

The programmability of these lights means you can change whether the location function is on or not (for the C1 and C2). When on, this uses the switch flashes all the time whether the light is on or not, allowing you to find it in a dark place. It does also mean that these switch flashes keep going all the time even in Firefly mode so the previous paragraph becomes more significant for firefly mode users. With Armytek’s low current circuit design you can leave this on permanently and not worry about draining the battery.

Also including a real Tactical monetary mode really adds another dimension. Make sure you correctly pre-select the mode you want to use, as in Tactical mode you can’t change level. Then to activate, from OFF, unscrew the tailcap slightly, press and hold the switch, and tighten the tailcap – you are now in Tactical mode. To get out of Tactical mode is not done the same way – you have to press and hold the switch (so it comes ON), then loosen the tailcap, then let go of the switch. Now when you tighten the tailcap again it will come ON, but be back in normal mode. If you don’t remember the difference of turning this mode on and off you can get stuck in Tactical mode.

A quick word on the in-light charging and the Uni C2 charger. In all cases the li-ion cell has not been taken up to a ‘full’ 4.20V, yet the discharge results have been good. For the health of the cells themselves it is actually good to not take them to an absolute 100% each time. So for every day use and frequent topping up, the Uni C2 won’t overwork your cells. Its memory means that if charging LiFePO4 cells and a power cut were to happen, it will safely continue the charging cycle for these cells – this is a detail often not included.

Magnetic abilities are a mixed bag for me. I’ve never been keen on the metal-to-metal contact these magnetic holding systems tend to use, plus their tendency to grab onto anything magnetic in bags and pockets. There are times a magnet holding your light is massively helpful though, so with the A1 and A2, their removable magnet is the perfect solution as you have a choice – thank you Armytek! With the C1 and C2 models on test here, you don’t have that choice due to the charger; but if you like magnetic tails on your lights then it is ideal.

With their feature packed user interface, you get great versatility. However, despite the single side-switch, these are not lights to give to non-technical people. With the variety of input clicks and wide variation in output levels, I can see those who are unfamiliar with multi-mode lights getting in a muddle.

Armytek’s interfaces are cleverly designed to give you great flexibility and functionality, I certainly appreciate the attention to detail.

Light Review: Armytek Prime Pro – PART 2 – A1 / A2 / Uni C2

22 February, 2019

In ‘Part Two’ we will be taking a first look at the Prime Pro A1 and A2, plus the Uni C2 Charger. – This is Part Two of a group review of four models of Armytek’s ‘Prime Pro’ range of lights (also included with the Prime Pro lights was the Armytek Uni C2 charger). When embarking upon this review I had not expected to generate quite so much content, so have had to split the review into three parts to make it more manageable. You will find links to these as each part becomes available.

Index:

Each title here will become an active link once it has been published.
Part One – A Detailed look at the Prime Pro Magnet USB C1 and C2.
Part Two – A Detailed look at the Prime Pro A1, A2 and Uni C2 Charger.
Part Three – Beamshots, Technical Testing and What they are like to use.

Taking a more detailed look at the A1:

As we go through the details of each light, for some there will be common features. In this case I may only show that feature for one of the models. In this part we have the A1 and A2 which are very similar as really the only difference is the cell and length of the battery tube. If you think a detail has been overlooked, check the similar model for that detail.

Taking a more detailed look at the A2:

Taking a look at the Uni C2 charger:

Rechargeable cells are the provider of ‘guilt free lumens’ so I hope you will be using them whenever possible. The Uni C2 is Armytek’s complimentary multi-chemistry auto charger, and is a perfect match for these lights and with its long list of supported cells, most of your other lights too.

Modes and User Interface:

This section is common across Part One and Two of the review to allow you to compare functions easily. It contains extracts from Armytek’s instruction manuals. Check the Armytek website for downloads of the full versions of these.

That is the end of Part Two.
