Light Review: Nextorch TA15, TA30 and Tactical Ring FR-1

Nextorch have always seemed happy to be a bit different, which is great for us as we get products that are innovative and unusual. This review is of the Nextorch TA15 and TA30 plus the Nextorch FR-1 Tactical Grip Ring. The TA15 supports several different battery types and sizes, and along with the more powerful TA30, has Nextorch’s dual-function tail-cap with magnetic control ring and two-stage button.

The TA15, TA30 and FR-1 as they arrived.

Taking a more detailed look at the FR-1:

With so much to look at, each model has a gallery of its own. This first one is of the FR-1 Tactical Grip Ring.

 

Taking a more detailed look at the TA15:

Next we take a look at the multi-power option TA15.

 

Taking a more detailed look at the TA30:

The slightly larger and more powerful TA30 is the last of the models we are looking at here.

 

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 main feature to note is that the bezel contours where the nano-ceramic glass-breaker balls are fitted do cut into the outer spill of these lights; most obviously on the indoor beamshots.

 

Modes and User Interface:

In previous reviews I have detailed the actual UI, but with the ease of access to user manuals, this section will now only include observations or differences in the operation.

In the process of tightening the tail-cap you also turn the magnetic control ring to the ‘Tac’ position. ‘Tac’ mode is actually ‘Off’ but you have direct access to maximum output from the tail-cap button switch (and Strobe from the second-stage of this switch).

This also means that to change modes using the control ring you are rotating it as if unscrewing the tail-cap. Being used to twisty interfaces where you tighten the tail-cap to turn on and then go brighter this has been counterintuitive for me, and I still find myself twisting it the wrong way when wanting to turn the lower modes off or down.

Unfortunately I can’t see any way round this, as it is completely right that when tightening the tail-cap (after replacing the battery) you want the control ring to be returned to the ‘off / Tac’ position; you just have to try and get used to this.

It also means that when taking the tail-cap off to replace the battery, you generally end up gripping the control ring and twisting this (especially with the FR-1 fitted), so turn the TA15 and TA30 onto maximum or strobe until the tail-cap is loosened enough to lock it out.

Batteries and output:

The TA15 runs on 14500, 16340, CR123, AA and though not officially, it can run on AAA.
The TA30 runs on 18650 or 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).

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.

* 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 which is different for each cell type used. For the:

TA15 when using 14500, the drain was 11.6uA (8.85 years to drain the cells)
TA15 when using CR123, the drain was 9.2uA (17.36 years to drain the cells)
TA15 when using AA, the drain was 58.6uA (3.7 years to drain the cells)
TA30 when using 18650, the drain was 16uA (18.54 years to drain the cells)
TA15 when using CR123, the drain was 32uA (4.99 years to drain the cells)

The runtime graphs show the full traces, and a zoomed in section of the first few minutes of the run.

 

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 TA15, TA30 and FR-1 in use

Starting with the FR-1, though described as being suitable for any standard size light (with tail cap of 23.2 mm to 25.5 mm diameter), as yet, I’ve not found any it works with beyond the TA15 and TA30. The tail-cap needs to be bigger than the battery tube, but for most of the lights I have, the tail-cap and battery tube are the same size. It does however work very well with the TA30.

When using the FR-1 and TA30, the FR-1 covers most of the tail-cap, and this means that to loosen or tighten the tail-cap, you have to hold the control ring switch and turn that. It also means that the control ring switch is not as easy to hold as the collar of the FR-1 reduces access to it slightly. Of course it does not reduce access to the tail-cap button switch.

Tactical grip rings do add bulk to a light, but they also give you so many grip options, which is why they are worth their weight in gold. From the simplest concept, that you can hang the light off a finger and actually free up that hand entirely to hold or lift something without putting the light down (think of it like wearing a ring with a very large stone in it). How you now hold it is only limited by your imagination.

 

Having got to grips with these lights, I am very impressed with the interface. Combining the rotary control ring with the two-stage tail-cap button has worked really well. From any mode, or off/Tac, pressing the button gives you direct access to maximum output. The two stage button switch has a good feel, being neither too stiff or easy to press, making the division between the half press for maximum output and full press for strobe well defined. Snatch the button and you will likely get some strobe, so if this is a big issue you’ll need to go for a single mode light.

Changing from pressing the button to rotating the control ring is natural. However, as explained earlier, the direction of rotation to change modes wasn’t intuitive for me, and I need to think about it.


(The TA15 with Nextorch’s new V30 EDC bag)

I like versatility; the TA15 gives you that, and is especially good as a light to have as a backup where you might need to scavenge cells from anywhere. The output does depend on the cells you fit, but this is not only sensible, as it better matches the output to the cells capacity (so not depleting them too fast) but it also lets the user choose their preferred output levels. I prefer lower output levels, so I generally run it on AAs. It really is very useful to be able to feed it such a varied diet, but you can end up with some cell rattle (mainly CR123) due to the mechanism needing to cater for the different cell lengths.

A minor point, which I raised with Nextorch, was that if using NiMh cells, the TA15 will often not switch from off to level 1, but needs to be turned onto level 2 then back to level 1. This behaviour seemed odd and only happened on NiMh AAs, but Nextorch explained that due to the low voltage, the TA15 was automatically going into a sleep mode to reduce drain to a minimum, and would only wake up when turned onto level 2. So this behaviour is designed into the TA15, and is specifically intended to reduce drain.

The TA15 and TA30 use the exact same interface and are in fact almost the same size. They handle very well and are extremely functional.

Still looking for an opportunity to try out the glass breakers…

Light Review: Nextorch GLO-TOOB, GT-AAA, GT-AAA Pro and GT-LITHIUM

Who doesn’t like a light-stick? Apart from the need for emergency marker lights, there is something great about a tube that just glows, and the main problem with chemical light sticks is that when they are on, they are on; until they go out forever. Nextorch have taken the light-stick and made it battery powered and even more versatile with its GLO-TOOB range. Now the reusable super durable emergency / safety marker light has an on-off switch and flashing modes, and can survive immersion up to depths of 3500m!

Taking a more detailed look at the GT-AAA:

We are going to start with the standard AAA model the GT-AAA, but first here are the three that are on test in their boxes. The Lithium and AAA models are in the older packaging, with the Lithium being the original model. The GT-AAA Pro is a more recent addition and uses updated packaging. One crucial difference between the models is their depth rating for waterproofing. The GT-AAA has the lowest rating at 60m, the GT-AAA Pro is good to 200m, and the ultimate is the GT-LITHIUM which will go to 3500m. (That is not a typo it really is three thousand five hundred metres.)

Back to the GT-AAA, the simplest and cheapest model, and this is what is in the box.

With a frosted casing, the GT-AAA has a keyring on one end and the black twist cap on the other.

Taking that black twist cap off, there is a very simple metal contact disk with raised centre.

The twist-cap’s plastic threads fit onto the aluminium threads of the battery tube.

With an AAA cell next to the GT-AAA you see how big it is.

With the cell inserted, its end slightly protrudes due to the internal spring. This forms part of the ultra simple switching mechanism.

A close up of the threads and O-ring (the end of the battery is also just visible).

Directions for turning the light on and off are marked in the twist-cap.

The LEDs are at the opposite end to the battery cap \ switch which is the keyring end of the GT-AAA.

Taking a more detailed look at the GT-AAA Pro:

There is nothing wrong with the basic AAA model, but the GT-AAA Pro immediately looks much more serious with its clear body and metal battery cap / switch.

Thanks to the clear body, you can see a bit more about what makes the GT-AAA Pro tick (or glow).

You can make out the PCB and LEDs through the casing.

The very end is a frosted finish, and this disguises the other side of the PCB.

In the case of the GT-AAA Pro, the keyring is fitted to a metal post making it much more robust. This also forms part of the switch mechanism; instead of the entire cap being rotated, the keyring and its post are twisted to activate the light.

The entire end cap is metal, so has metal threads instead of plastic.

Look at the middle of the cap. This is the cap in the OFF position.

Twisting the keyring pushes the middle of the cap forward and turns it ON.

With the battery fitted you can see how the middle of the battery cap will make contact with the battery terminal when it pushes out. The cell wrapper acts as an insulator allowing this switching method to work.

On the side are markings to confirm which way round the battery goes in. This follows the almost universal ‘positive terminal in’ direction.

The GT-AAA Pro switched ON.

A closer look at the lit up LEDs.

Taking a more detailed look at the GT-LITHIUM:

Last up is the most serious of all of the GLO-TOOBs, the LITHIUM. Notice that there is a switch cap already fitted, plus a second cap with keyring.

Already fitted to the GLO-TOOB LITHIUM is a click switch. This is mostly metal, but with a rubber switch boot.

On the opposite end of the GLO-TOOB is a black plastic end cap which the other models don’t have.

Having a clear body, like the GT-AAA Pro, you can look inside at the LEDs. In this case 5mm type LEDs are used, but the LED’s clear casing almost disappears in the clear resin used for the body of this light.

The click cap might be easy to use, but for the ultimate in resilience you need to use the diving cap switch (twist switch with keyring), so let’s swap them over.

While we are swapping them over, the contacts on the click switch look like this.

Unlike the GT-AAA Pro, here the keyring and its post are fixed (and you use them to screw the cap into place), with a plastic rotating switch ring instead.

To keep the contacts totally fresh, there is a metal protective cap supplied with the twist switch cap.

Now the protective cap is fitted to the click switch.

A CR123 fitted into the GT-LITHIUM. Battery orientation is marked in the red coloured band.

This version is the Red LED one.

A closer look at the lit up 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 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!

Clearly, being light-stick style, marker lights, there is not really a ‘beam’ to show, instead I’m showing each one at a short distance (3-4m) from the camera.

This is the GT-AAA; actually all three are hanging next to each other on a clip.

At the same exposure, this is the GT-LITHIUM.

With the GT-AAA Pro up last. This appears quite a bit brighter than the GT-AAA.

All of them on at the same time. The red of the GT-LITHIUM is a bit drowned out.

The camera is set to daylight WB (as is the case with all my beamshots) to try to make colour and tint as clear as possible. The amber GT-AAA and GT-AAA Pro take over, masking the GT_LITHIUM’s red colour.

Modes and User Interface:

Each of the GLO-TOOBs is slightly different in its operation so we’ll take them one at a time:

The GT-AAA has three modes, High, Low(25%) and Flash.
To switch ON, tighten the entire end cap.
To cycle through the available modes twist-ON, then twist-OFF, and back on again within 2s and repeat to change from High – Low – Flash – High etc.
To Switch OFF, loosen the entire end cap.

The GT-AAA Pro has three modes, High, Low(25%) and Flash.
To switch ON, turn the keyring as if tightening a screw.
To cycle through the available modes twist-ON, then twist-OFF, and back on again within 2s and repeat to change from High – Low – Flash – High etc.
To Switch OFF, turn the keyring as if loosening a screw.

The GT-LITHIUM has 11 modes, Equal Flash, Beacon Strobe, Fast Strobe, Slow Strobe, SOS, Pulse, Half Flash, Bounce, Ramp Up, 100% Constant On and 25% Constant On.
To switch ON to the memorised mode, either click the switch or turn the end cap.
To switch OFF, either click the switch or turn the end cap.
To set the current output mode, switch ON, count 5s, then switch OFF and ON again. Now you can cycle through the available modes (in the order above) by turning it OFF and ON again until you get to the one you want. To ‘fix’ that mode, simply leave it ON for 4s and it will be memorised.

Batteries and output:

The GT-AAA and GT-AAA Pro run on a single AAA Alkaline cell, and the GT-LITHIUM runs on a 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).

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.

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

There is no parasitic drain on any model.

With such low outputs and long runtimes I have not included a runtime graph for any model.

Troubleshooting

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

There was one slightly odd observation with the GT-AAA Pro. During the first few full runs (turning it onto high with a fresh cell, and leaving it to run until is went off) the PCB end of it started to dome out, as if there was some pressure building inside. It was also observed when fitting a mostly depleted cell and then leaving it on high.
I suspect the cell might have been gassing, and this pressure blowing the PCB out a little.
It was not observed after the fourth cell was used, so might have been connected to something on the PCB creating a pressure build up.
Not being able to replicate it any further, I asked Nextorch about it and they replaced the GLO-TOOB. The replacement did not exhibit this behaviour at all.

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 GLO-TOOBs in use

With the GLO-TOOB lights being marker lights, in general, to use them you simply attach the light to whatever you want to mark. The main aspects to discuss here are the user interfaces and battery change.

Each of the three models in the review is constructed differently so despite being similar overall they do feel quite different in use.

Starting with the lowest end model, the GT-AAA, and to operate this you have to turn the entire black cap. Of all three this is the stiffest to operate, and though not requiring much force to turn it, it does require reasonable force to be able to grip the cap strongly enough that you can turn it. This is due to the cap being relatively smooth to hold.

The operation is simple, very immediate and easy to judge as the cap position is obvious. The High output level is clear and has a useful level of light, but in comparison to the other GLO-TOOBs in this review, the Low uses a low frequency PWM making it quite obvious, and the flashing mode is a bit manic, being more of a strobe than a beacon.

Stepping up to the GT-AAA Pro, and there is a leap in performance and build. This time the battery cap is metal, and has a central threaded post which is used to operate the light. Starting with a battery change, you then screw in the cap, and tighten fully; at all times this cap is fully tightened. Now to operate the light, you twist that threaded post using the keyring (or you can hold the ring in place and twist the body. This action is super smooth and possibly the easiest action of all the GLO-TOOBs. It does seem a little vague though as it lacks any real feel until the unit comes on. At this point the action stiffens and becomes a bit grindy; I am slightly worried about over tightening this switch as it might crush the battery.

In terms of output, the High mode is great, making it so much nicer to use. And when it comes to the flashing mode, though not quite a ‘beacon’ the flashes are much slower than the GT-AAA and so much easier to be around. The increased waterproofing and the significantly better low and flashing modes make this Pro model a worthy upgrade to the GT-AAA.

Lastly, the much more serious Lithium model. It is more expensive than the AAA models, but one important reason you might consider this the ‘serious’ version, comes from the CR123A cell’s shelf life. You can put a fresh CR123 in this and leave it for 10 years and it will work. I’d certainly not expect the same out of an alkaline cell. In addition to the power source, the build of the GT-LITHIUM is seriously strong, and it has a ‘diving’ switch cap designed to make this usable to 3500m depth. Not many people will even use that level of waterproofing, but it does mean that overall you are getting a massively robust light. Optionally you can also use the click switch cap instead for a different way of using it.

Now we also have 11 modes to choose from, and my biggest complaint is finding it hard to choose one, as they each provide a different mix of visibility and attention grabbing. My favourite visible but not too manic is the ‘pulse’ mode, with another that works well for me is ‘Bounce’. The others are each so good, you have trouble choosing between them; the only one I’ll never use is the Fast Strobe. Depending on your application, battery life might be a consideration, so the total time the LEDs are lit are a factor. In this case the Slow Strobe or Beacon Strobe would be good choices.

Both switch cap types are equally easy to use. In some ways the click cap makes mode selection easier, but doesn’t have the solid hanging ring or levels of waterproofing as the diving switch cap does. The twist action is a smooth ‘detent’ 1/4 turn to go between on and off. Grip is very good with the deep scallops round the ring.

Unlike the GT-AAA Pro, when fitting the diving switch to the GT-LITHIUM, you now use the keyring to twist the cap on tightly; you can’t use the twist ring itself as it moves.

One of my main reasons to use this type of marker light is as additional safety lighting when cycling. Typically attached to something behind me, I don’t get to see it, so because I like these, I am constantly looking for an excuse to use them. Things like tent marking, or even leaving a slow strobe on my car dashboard when parking the car at night in a public car park are amongst the ‘excuses’ I’ve come up with.

If you like light sticks then these GLO-TOOBs should be on your shopping list.

Review Summary

_______________________________________________ _______________________________________________
Things I like What doesn’t work so well for me
_______________________________________________ _______________________________________________
‘On-Demand’, reusable light stick. GT-AAA uses PWM for low mode.
Incredible 3500m waterproofing on the GT-LITHIUM. Light not as evenly spread along the length as a chemical light stick.
GT-LITHIUM has 11 modes to choose from. Currently limited to AAA or CR123 cells (an AA option would be great).
Choice of 3 modes for the AAA versions.
Keyring makes it easy to attach.
Super tough and resilient.

Light Review: Nextorch P5x Series with ‘Dual-Light’ LED Swapping Mechanism

Multi-LED lights have always had to compromise the main beam by using multiple smaller reflectors or combined ‘compound’ reflectors, both of which affect the beam considerably and create many beam artifacts. With such powerful LEDs to choose from now, it has become more desirable to make the humble torch/flashlight more versatile by giving it more options. Nextorch have re-thought the concept of multi-LEDs, and designed a ‘Dual-Light’ system that allows the user to actually swap the primary LED that is positioned at the focal point of the reflector, so fully maintaining beam quality. The P5x series of lights (part of the ‘Police’ Series) use a special mechanism that changes the active LED and moves that LED to the centre of the reflector, ensuring the beam quality is uncompromised and giving you two beam options in one light.

Taking a more detailed look:

A few different versions of the P5x were provided, and they had slightly different packaging. The box at the front shows the six variants you can choose from; P5G, P5B, P5R, P5W, P5 UV and P5 IR.

For one of the box styles, this is the inside.

The other box style has a moulded plastic tray insert.

Either way, you get the P5x a Nextorch 18650, a USB charging cable, a lanyard and the instructions.

The LED changing mechanism and built-in USB charging blend into the simple, elegant design.

A flattened section of the grip texture provides a space for the engraving.

If you want to add a lanyard to the P5x, you need to snap on the lanyard ring.

The lanyard ring sits tightly into a groove near the tail-cap.

A sleek tail-cap design hides the USB charging very well.

The power switch protrudes slightly and is easily accessible, however no tail-standing is possible.

If it were not for the small engraving of the USB symbol and an arrow, you might miss the charging function.

Following the arrow, simply pull the tail-cap sleeve up and turn it sideways to lock it open.

A micro-USB socket is used for the charging.

USB charging cable connected.

Opposite the USB socket is a charging indicator light. Red while charging, Green when fully charged.

Taking off the tailcap, the negative contact is a sprung button instead of an exposed spring.

The threads are a standard trapezoidal thread and are bare aluminium.

Peering into the battery tube, the positive terminal is a spring.

Looking closely at the head of the P5x, there is an indicator arrow. Here the White LED is selected.

And now the Green LED is selected.

Our first close-up look at the textured reflector and dual LEDs. The white LED is in the central position.

Now the green LED is centred and active.

With the White LED on.

Then the Green LED on.

White LED centred in the reflector. (Note the yellow phosphor colour.)

Going in even closer with the XP-L V5 LED in the central position and the green XP-E2 LED to the side.

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!

Each P5 light features a white LED (XP-L V5), so I’m only showing one of these as they all look the same. With this being a dual-LED light, the beam is very clean without the artifacts you might expect from a multi-LED light. The spill is a medium width and the hotspot transitioning smoothly into the even spill.
All of the beamshots shown here have the same exposure for all beam variations.

Now onto the interesting secondary-LED options. The Warm LED is quite warm (XP-E2 Warm), in fact it is reminiscent of a good old incan but without the curly filament artifacts. The camera is set to daylight for all beamshots to show the relative colour shift. As with the white beam, the Warm beam is clean and free of artifacts.

Similarly with the green (XP-E2 Red), a nice clean beam.

Being UV (1000mW UV), this beamshot is not a very good representation as there is no fluorescent material in the beam; it makes it look very dark.

An lastly the Red LED (XP-E2 Red). The spill of this beam is slightly wider than the other colours.

Moving outdoors now. Again all exposures are the same. Starting with white.

Onto Warm White.

Green.

Clearly UV is not ideal for lighting up your garden, but that is not why you use it. You can see that there is a good throw, despite the lack of fluorescent materials.

And lastly Red. In this case it was a different evening and there was a light rain which is why the beam is showing up more strongly.

Modes and User Interface:

All of the P5x models have the same simple set of modes and user interface.

Control is via the forward clicky tail-cap switch, and there are two constant modes, High and Low as well as Strobe and SOS. Of course with the Dual-LED, this is the same for each LED.

To Switch ON to High, from OFF, half-press or fully press the switch. Momentary action is always on High.
To access the Low mode, from ON with the switch clicked fully on, half-press the switch briefly to access Low. Low can only be accessed from High with the switch clicked ON.

To switch OFF, either release the switch, if only half-pressing it, or press it fully to click it off.

For Strobe, rapidly double-tap the switch from OFF. This must be half-presses, and once Strobe is activated, you can fully click the switch to lock it on.

For SOS, first the P5x must be ON with the switch fully clicked. It can be in High or Low. Then half-press the switch for 3s and SOS will start.

LED swapping is via the control ring at the base of the head. Rotate this to select the LED. You can do this at any time, whatever mode is selected.

Batteries and output:

The P5x runs on a single 18650, which it can recharge, or two primary CR123s.

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.

* 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 measured 16400 lx @1m giving a beam range of 256 m.

There is parasitic drain at 11uA (27 years to drain the cells).

In this first runtime graph there is also a trace from the green output of the P5G. Compared to the white output, this is longer and lower so is included here to give an indication of the reduced efficiency of the coloured LED.

In the second graph the green output has been removed to better show the white outputs. Instead look at the White output from the P5UV and the Warm output from the P5W. Again the cool white LED is more efficient and provides a longer runtime. The Warm White keeps up with the Cool white up to about 2 hours, then drops off with the Cool white running for another couple of hours.

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 P5x series in use

I first saw the Nextorch Dual-Light mechanism at IWA 2016 and immediately loved the idea. I asked them if they could add a third LED – yet to be seen – and the reply was ‘maybe’; we can live in hope.

Having used many multi-LED lights with different colours in them, though useful, the beams of the secondary LEDs were always badly compromised, and even the main beam was compromised. The Dual-Light is a revelation with the main LED effectively being swapped with a twist of the selector ring – you don’t even need to turn it off.

A trio of dual-lights getting ready to go.

We have had a detailed look over the P5x lights already, but to really show the mechanism, this is a short video of the way it works.

Although it has the LED swapping function, Nextorch have made the P5x a simple and functional light without any external frills. The LED control ring has slightly raised grips which provide a degree of anti-roll, at least enough for relatively level surfaces. There may not be a ‘tactical grip ring’ but the slightly wider tail-cap is enough to let your grip the light securely, and the grip pattern works well (it is not knurling, as the pattern is cut, not rolled).

Fitting the lanyard ring also gives a little more grip (plus you can have a lanyard), but in doing so, I managed to scratch the anodising both fitting and removing the ring, so if you are going to use it, fit it once and leave it on.

Of course it is very convenient to have built-in USB charging, especially if you travel with the light. What would have been useful is to have some indication of the state of charge. There is none, so it is difficult to know if you need a charge or not. Unfortunately this leads to regular topping-up rather than a more planned approach to charging.

Though limited to two output levels (and I generally prefer a few more options including ultra-low) those levels are well chosen for most uses. The lower level at around 40lm is great for indoor use and is perfectly comfortable to use at close range, and the 700lm High level is a good powerful output which a single 18650 can power without being over-burdened.

In the case of Nextorch’s Dual-Light P5x models, the ‘secondary’ LED is actually not secondary at all, instead you have two ‘primary’ LEDs both of which have full and uncompromised use of the reflector, making them as good as dedicated lights using the same LEDs. Your only difficult choice now is which combination of LEDs to go for.
