    Drool Thrunite Archer V2 (XP-L V6 Cool or XP-G2 Neutral) 1A, 2A, 1C, 2C Series Overview

    Warning: More pic heavy than usual.

    Thrunite has sent me a complete set of samples of their new Archer v2 line, including both Cool White (CW) XP-L and Neutral White (NW) XP-G2 versions. As with the recent Neutron series, the battery configuration is identified in the model number (i.e. 1A is 1xAA, 2C is 2xCR123A, etc.).

    I have on hand for this review the Archer 1A CW/NW, 2A CW/NW, 1C CW/NW, and 2C (CW, as there seems to be no NW version as yet).




    As usual, I will start with a description and overview of the common build, user interface and circuit functions. I will then provide detailed testing and comparison of each model relative to its respective peer groups. To keep the review size down, I will just use representative build pictures from among the different models. But there is no way around it – this is going to be a long one. Buckle up …

    Packaging is the same for all models, and includes a hard cardboard box with packing foam (a sticker on box indicates cool white or neutral white). Inside, you will find the light (with pocket clip installed), extra o-rings, extra boot switch cover, basic wrist lanyard, and manual.

    Note that Thrunite has recently updated their warranty policy for all lights, available here.

    As with other series reviews, I will start off with a discussion of the common physical build and user interface/circuit functions. I will then provide separately (by model) beamshots, testing measures and runtimes.

    Common Build

    Here are a series of general pics:

    Archer 1A:








    Archer 2A:



    Archer 1C:


    Archer 2C:




    Physically, the new Archer lights are very similar to one another. Indeed, it is just the 2C that has a wider body (to accommodate the thicker 18650 cells) – the heads look the same across all models. All lights feature a classic tailcap clicky-switch for on/off, as well as side electronic switch for mode changing.

    All lights have knurling, which is of reasonable aggressiveness, and glossy black anodizing. Hand feel is good, and the included clips help with grip (and serve as anti-roll).

    The tail-switch is a typical forward clicky switch, with a raised surround (that serves as a lanyard attachment point and allows stable tailstanding). The side-mounted electronic switch protrudes slightly, and has a definite "click" (with typical traverse). The center of the switch is clear, but there doesn't seem to be an LED indicator underneath (as there is on some of the other recent Thrunites).

    The only difference inside the lights is on positive contact board in the head – the 1A, 1C and 2A models have the classic reverse-polarity feature seen on many AA lights (i.e., only small button top can be used). The 2C lacks this feature, and so will take flat-top cells just fine.

    Screw threads are square-cut and anodized, allowing lock-out on all models. Oddly, there are some differences in the tail threading, and only the 1A and 2A have interchangeable tailcaps.






    The new Archers use a crenelated bezel design, in stainless steel. Reflectors are smooth finish, and appear to be identical across models and emitter. Centering of the emitters was reasonably good on samples (although not perfect). The Cool White versions come with the XP-L emitter, the Neutral Whites the XP-G2.

    Scroll down for specific beamshot comparisons for each model/battery config.

    Common User Interface

    Turn the lights on/off by the physical tail switch. Switch is a forward clicky, so press and hold for momentary on, click for locked on.

    You change modes by use of the side electronic switch. Click (i.e., rapid press release) to advance through modes. Mode sequence is Firefly > Lo > Med > Hi. There is a "hidden" Strobe mode accessible by a press-and-hold of the side switch.

    The light has mode memory for the constant output modes, and retains the last level set when you turn it off/on (i.e., no memory for Strobe).

    Video:

    For information on the lights, including the build and user interface, please see my video overview:



    As with all my videos, I recommend you have annotations turned on. I commonly update the commentary with additional information or clarifications before publicly releasing the video.

    As an aside, if you want to get an instant notification for every new review that I post here on CPF, you can subscribe to my YouTube channel (the vids go public at the same time). Just mouse over my logo watermark on the video for the subscribe feature to open up. You may need to tap or click, depending on the platform you are using to watch.

    PWM/Strobe

    The new Archer v2 series lights are current-controlled on all modes – there is no indication of pulse width modulation or circuit noise on any constant-output mode, on any model.



    Strobe is a consistent 12.8 Hz on all models, although there is variation in how the oscilloscope traces looks:

    Archer 1A CW:


    Archer 2A NW:


    Archer 1C CW:


    Archer 2C:


    None of this is visible to the naked eye – in all cases, strobe is a consistent "fast" strobe across this series.

    No Standby Drain

    Since the Archers all have a physical clicky switch, there is no standby drain when the lights are off.

    Testing Method:

    All my output numbers are relative for my home-made light box setup, as described on my flashlightreviews.ca website. You can directly compare all my relative output values from different reviews - i.e. an output value of "10" in one graph is the same as "10" in another. All runtimes are done under a cooling fan, except for any extended run Lo/Min modes (i.e. >12 hours) which are done without cooling.

    I have devised a method for converting my lightbox relative output values (ROV) to estimated Lumens. See my How to convert Selfbuilt's Lightbox values to Lumens thread for more info.

    Throw/Output Summary Charts:

    My summary tables are reported in a manner consistent with the ANSI FL-1 standard for flashlight testing. Please see http://www.flashlightreviews.ca/FL1.htm for a discussion, and a description of all the terms used in these tables. Effective July 2012, I have updated all my Peak Intensity/Beam Distance measures with a NIST-certified Extech EA31 lightmeter (orange highlights).

    Potential Issues

    The side switch button is fairly small, and may be hard to locate by touch alone (even though it is slightly raised).

    All lights show a timed step-down from Hi after ~3.5 mins runtime (except on 1xAA batteries).

    Most models are not driven as highly on max as other recent lights in their respective classes. However, they all produce a reasonable Hi level.

    Preliminary Observations

    Ok, that's a LOT of data.

    Let me start with the physical build, since it is fairly consistent across models. Personally, I found the Neutron v2 refresh in 2014 to be a bit "plain vanilla" in styling. As such, I'm happy to see that Thrunite has kept a more traditional design for the Archer v2 update.

    While this design is not particularly novel or innovative, it has the advantage of being familiar and well thought-out (i.e., very similar to a number of Fenix and Olight lights over the years). I like the forward clicky switch (with ability to tailstand), the side switch for mode changing (with low voltage warning underneath), the decent bi-directional pocket clip, the stainless steel crenelated bezel, and the reasonable knurling.

    I like the user interface, with its separation of on/off from mode changing. The mode sequence (and level spacing) is generally good, with strobe mode "hidden" under a press-hold of the side switch.

    Circuit-wise, all models show a good customized current-controlled circuit, with reasonable interface. Output/runtime efficiency is typically excellent - very similar to the Olight and Skilhunt series lights, and the earlier Neutron V2. Regulation patterns are similarly good, with most models (on most levels) showing flat stabilization. Please see the individual runtimes above for more information on the model relevant to you.

    Output levels and beam intensity are generally consistent with Thrunite specs. As a general rule, Hi output increases as you go up to higher voltage sources on any given model, but the Firefly-Med modes remain relatively unchanged. Again, please see my detailed summary tables earlier in this review, for the individual models you are interested in.

    Beam patterns are also good for the series, with a reasonable trade-off between center beam throw and spill. It is nice to see the option of the XP-G2 Neutral White or XP-L Cool White emitter on each model (except the 2C so far). There is not a big output difference on most models (on most batteries), although the NW versions to tend to be a bit throwier (thanks to the smaller emitter die). I am surprised to see how low the prices are for these lights, considering everything you are getting here (especially for the NW versions).

    There really isn't much to criticize here. Thrunite has done good job in providing an extensive series of lights with a consistent interface and build - but customized circuits for best performance. You also get the option of Neutral White and Cool White for each model (except the 2C at present), with a lower price point for the Neutral White version. Frankly, either tint seems to be a bargain for the various battery classes. A very nice series at an even better price - I can certainly see the new Archer series doing very well for them.

    Thanks for the review!

    2C? That light is the only one not on their website, odd.

    Yes, I think that is because the final specs have not been determined yet. The 2C sample I have certainly performs well, as with the rest of the (published) series.

    Looks like a good alternative to the P12-styled lights, shorter and narrower than the rest. The only thing I would have liked to see would have been an option for bezel-down carry.

    Well, because of the large loops, the clips all allow bi-directional attachment (granted, not as as securely bezel down). And on the 1C, you could easily reverse the orientation of the clip and still have everything fit.

    What about the energy spent while off? I have heard some issues about it.

    The center of the switch is clear, with a red LED indicator underneath (i.e., similar to some of the recent Olights).
    Is there really an LED under the button? I've never seen any low voltage indication on my Archer 1A V2s. Maybe some models have it and others don't?

    You know what, I'm not not sure now. I thought I had seen that in one of the runtime tests, but I have been putting a lot lights through my lightbox recently. I know there wasn't any sign of it for sure on the 1C, since I was looking at that light when it was nearly dead. Let me double-check the others.

    EDIT: Just checked, and none of the the lights seem to have a low-voltage feature. I will edit that line in the review.

    Those stainless steel striker bezels. I've taken my Archer 1A V2s on some night time hikes and now I've got holes in both my front pockets. Could be an issue for people who intend to pocket-carry these lights.

    Got my 1c v2 NW today from Amazon/Thrunite. I have several Thrunite lights and they have all been great. This one not so much. Opened up the package put in a RCR turned it on, went through the modes then left it on high as I do all my new lights and check the temp of the body at different times. Between 1 and 2 minutes on high the light shut down. I had to cycle the tail switch to get it to come back on. After another minute it shut down again. Replaced the RCR with another RCR and the same thing happened. Put in a CR and it worked fine. After about 3 1/2 minutes it throttled back like SB stated. I completely drained the CR and the light worked fine. Put in another freshly charged RCR and it shut down in about a minute. That was it for me. It is now boxed up to return. I have always liked Thrunite and believe I just got a bad sample and understand these things do happen. Not sure if I will order another one. The NW tint looked great. Warmer than my S10 L2 NW.

    @Selfbuilt - Can you please confirm, it looks like there is a blue O-ring underneath the glass, between the reflector and and lens?


    This was an issue I took with the previous version of the Archer 1A, bought directly from Thrunite... there was no o-ring seal in the head, and the second o-ring they included was too small to put there.

    Selfbuilt, your output/runtime graphs (for the higher modes) and estimated lumen charts (across all modes/batteries) are very helpful to users and I think go a long way toward keeping manufacturers reasonably honest on their marketing specs. The one big hole for objectively covering all the test dimensions are runtime tests across the lower modes.

    While it is, of course, way too much work to actually run these tests, do you think it would be worthwhile to provide a simple tailcap current measurement chart for those lower modes that you do not test for otherwise? It would only require a few extra minutes of your time and would go a long way in the completeness of your review.

    FWIW, after running many side-by-side output/runtime tests on moonlight and lows (which I use most), I have personally come to find that tail cap current measurements are quite accurate for well regulated lights.... certainly enough so, that I will no longer be doing runtime tests on low lows myself.

    As one example, Thrunite is claiming ~800 lumen-hours per AA on low here.... (again):

    TN also once claimed ~800 lumen-hour per AA spec is their Neutron 2A V2 (11 lms for 72 hrs for 1AA, as per your review and my manual), but my runtime tests and tailcap measurements show it to be less than half that (which is still very good efficiency). TN has subsequently amended that spec, along with it's 1 month/AA firefly spec - although, the new FF spec still seems overstated, by multiples, based on my sample's 20ma/1Eneloop tailcap reading (which is not efficient).

    I had once assumed that a light's efficiency on the higher modes would also translated to efficiency across the lower modes.... but that is not true.

    There are a number problem here, I'm afraid. First off, not all lights have easy access the lowest modes from strandby/off. Even just doing standby mode testing, I have burnt out more than a couple of DMM uA ports over the years by accidentally slipping with my leads and accessing a higher current draw mode. Even with fuses, I find this typically toasts a DMM's uA port. If I tried to actually routinely measure lower output modes as well, I'm sure I'd go through them even faster! You would also really need to use bypasses and shunts to get around high mode sequence issues, which I'm afraid is bit beyond my electrical skill set.

    More generally though, I worry about the ability to extrapolate from lights that use different types output regulation. It is reassuring to hear that you are finding good correlations, but I know there are a lot of pitfalls. For example, PWM-controlled lights are particularly known to be difficult for DMMs to accurately measure (depending on the DMM, and the PWM frequency). But even current controlled lights could vary depending on the regulation pattern, battery source, etc. Here again, best thing would be to have an external power source to directly interrogate (as HKJ does). I'm afraid beyond my experience or resources - you are going to have to rely on others to do current draw measures of lights you are interested in.

    it looks like thrunite has taken the listing for the 2C down, anyone know why?

    The darkness is not my enemy, it is just where they hide: my fears, the unknown, and those that would do harm fear the light. I must always carry it with me to dispel the darkness and reveal the truth...
