    Smile Olight M20 Warrior Review - Premium R2 - RUNTIMES, BEAMSHOTS & DETAILED COMPARISONS

    Reviewer's Note: This is a review of the Olight M20 Warrior Premium R2 light (2xCR123A/RCR, 1x18650). The M20 was provided for review by MattK from www.batteryjunction.com.

    UPDATE 4/25/2009: The Olight diffuser and red/green filter covers for the M20 have been added to the end of review

    The M20 "Warrior" is Olight's new high-end 2xCR123A build light, designed for tactical uses.



    Olight M20 Warrior Features (consolidate from multiple sources):
    • Available with Cree Q5 (WC tint bin) or premium R2 (WH tint bin)
    • Protruding tactical momentary-on forward switch, or click to lock on
    • Three "digitally-controlled" brightness output levels and a tactical strobe
    • Memory for instant on at the last output level or mode used
    • Low battery indicator (blinks three times every 20 seconds when battery power is low)
    • Reverse polarity protection
    • Stainless steel strike bezel, removable
    • Full orange peel reflector (standard), optional smooth reflector available
    • Rugged aluminum body (Mil-spec: MIL-STD-810F) with Type III Hard Anodizing
    • Quick release lanyard
    • Rated at IP-68 for enclosure resistance to dust & water (waterproof 1M+)
    • Anti-shatter ultra clear lens, with anti-scratch coating
    • Tailcap lock-out function to prevent accidental activation
    • Anodized aluminum grip ring, removable
    • Built-in steel pocket clip, removable
    • Regulated output
    • Battery magazine to prevent 2xCR123A batteries from rattling in the battery tube (spares available) - magazine use not required
    • Optional remote pressure switch and weapon mount expected soon, M20 should be compatible with most current 1" mounts




    Light comes with an attached anodized steel pocket clip and aluminum grip ring (both are removable), high-end holster, plastic battery magazine (to prevent CR123A rattle, but use not required), manual, good quality wrist lanyard, extra o-rings and extra GITD plastic tailcap boot cover (looks clear, but glows a blue-teal colour). A good package.


    From left to right: CR123A, 18650, Olight M20, T20, JetBeam Jet-III PRO ST, Jet-III PRO IBS, Romisen RC-M4.

    As you can see, size is bit larger than the more compact general-purpose 2xCR123A lights, but still quite comfortable in the hand. Certainly much smaller than the dedicated thrower lights - the M20 is actually a bit smaller overall than I expected for a light with all these build features.

    Weight: 120.0g
    Length: 144.0mm
    Width: 35.7mm (head, widest portion), 24.8mm (tailcap)







    The M20 is a well made, high quality light. All components feel very sturdy and well built. Everything fits together well, with double o-rings and smooth screws threads at all openings (tailcap threads are anodized, allowing tailcap lockout). Tailcap spring is not exposed, but encased within an assembly with a button top. There is a spring mounted on the positive contact board in the head.

    Battery magazine works well to prevent rattle with 2xCR123A. My only concern here is the thin plastic screw threads on the magazine cap might not stand up to a lot of abuse. But the magazine is optional anyway - the spring in the head provides enough resistance to prevent any noticeable rattle.

    Machining and anodizing of the light are top-notch on my sample. The raised checkered portions help with grip. While not as "grippy" as aggressive knurling, it seems to work pretty well with my hands. The attached anodized clip and grip ring also help enhance grip, and both are removable. Overall, I would have to say hand feel is excellent in all configurations.

    The light can't tailstand - but that's not uncommon for "tactical" lights, since tailstanding rings tend to obstruct easy access to the clicky switch. Light comes with a forward tactical clicky with good tactile feel (momentary on, click for lock-on).




    The light features a scalloped stainless steel bezel ring, which could serve as a strike bezel. The reflector is fairly deep, with what I would describe as a medium orange-peel texturing (MOP) - optional smooth reflectors are also available for even greater throw.

    Since mine is the premium R2 model, tint is the expected warm greenish tint (WH tint bin). This is fine for me, since I actually like warmer tints - but if you like yours more cool, you should stick with the Q5 bin (WC tint). The relatively deep reflector should translate into decent throw.

    For beamshots, below is a comparison to the Solarforce T7 (which is very similar to a Fenix P3D) and JetBeam Jet-III PRO IBS (which is a good mid-range thrower). All lights on max on AW 18650/14670 (pics taken ~0.5 m from a white wall).






    As you see in the pics, the M20 beam pattern is close to the original Jet-III PRO IBS, which has a roughly similar sized OP reflector. This means you get pretty decent throw, while minimzing Cree rings in the beam. For a more detailed throw/output comparison, see my Summary chart below.

    UPDATE: Some additional long-distance beamshots, to show you how the light compares to others in its class.

    Please see my recent 100-yard Outdoor Beamshot review for more details (and additional lights).






    User Interace:

    UI is straight-forward - press the forward clicky for momentary on, click for lock-on.

    Light moves between brightness/mode states by a simple switch of the head - loose/tighten the bezel to move to the next state. Sequence is: Lo - Med - Hi - Strobe, repeated in an endless loop.

    This switching mechanism is similar to all other Olights, but the selection of states is different on the M20. Most Olight models switch between 5 output states with no strobe mode, in a Hi to Lo sequence. The revised M20 sequence (i.e. Lo to Hi) and better spacing between the levels (i.e. Lo mode is lower than other Olights) is an improvement, IMO.

    Testing Method: All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlightreviews.com method. 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 the extended run Lo/Min modes which are done without cooling.

    Throw values are the square-root of lux measurements taken at 1 meter from the lens, using a light meter.

    For the runtime/output comparisons below, I've included the following lights:


    From left to right: Olight M20, Solarforce T7, ITP C6, Regalight WT-1. Not shown, Fenix T1.

    Throw/Output Summary Chart:



    As suggested by the beamshots, throw on the M20 is very good - slightly better than the Jet-III PRO IBS in fact. I would expect even better throw with the smooth reflector (not tested).

    Overall output is excellent - for initial output, it beats all the other 2xCR123A/RCR or 1x18650 lights included in this round-up comparison (although some only by a small margin, on certain batteries). Definitely an excellent performer, but see my runtimes for more info.

    Output/Runtime Comparison:

    Before all the detailed runtimes, here is a comparison of the different batteries on max on the M20:



    As you can see, rock-solid regulation on RCR and CR123A. And as expected, the light runs in only semi-regulated fashion on 1x18650 Li-ion. This is hardly surprising, since any multi-power light that can handle >8V input in a regulated fashion is going to have trouble providing the same regulation for 3.7V Li-ion.

    But how does it compare to the competition?





    A few comments on Max output:
    • Max output of the M20 matches (or leads) the pack of my multi-power CR123A/RCR/18650 lights, on all batteries.
    • The M20 appears to be one of the most output/runtime efficient of all the multi-power CR123A/RCR/18650 lights in my collection (presumably thanks to its R2 emitter)
    • Output on 18650 is only semi-regulated, but exceeds all my other multi-power lights.






    • When matched for Med output, the M20 again appears to be one of the most output/runtime efficient of all the multi-power CR123A/RCR/18650 lights.
    • Note that the Medium output level seems to be set at a good brightness level (i.e. ~50% of max).




    Honestly, I haven't had time to do anything more than the RCR lo mode runtime test - for the simple reason that performance is outstanding at this level:
    • Runtime on Lo on RCR is a phenomenal 3.5 days! Based on this result, I would expect a good week of runtime on 18650 on Lo (and no, I don't plan to test that in my lightbox ... )
    • Although some of my 18650-only PWM-based continuously variable lights are capable even lower outputs, this is one of the lowest Lo output levels I've seen on a multi-power CR123A/RCR/18650 light.
    • Although not shown, the regular Olight T20 is about twice as bright as the M20 on its minimum output level
    • Output/runtime efficiency is clearly excellent for this output level (~5% of max).


    Potential Issues

    I have no qualms about the build quality of this light so far - no signs of any problem in my testing to date.

    My only potential concern is the low battery warning flash. As you can see in the runtimes, this gets triggered on 18650 and primaries almost as soon as the light falls out of regulation. Personally, I have always found these warnings to be superfluous, since the lower output is itself an excellent indicator that the battery is running low. Moreover, these warning flashes are actually annoying if you need to run the light for the several hours it is capable of at these low levels (i.e. in an emergency).

    But the greater concern is that (inevitably) some batteries in some lights will trigger an erroneous low voltage flash even when the cells are still relatively fully charged. This mistaken voltage sensor effect has been reported for every model light that I've seen with such a high trigger-level. And a quick perusal here at CPF confirms several members reporting exactly this problem for their M20s. Note that I have not experienced any problem with my M20 - but IMO, it's better to just dispense with this feature altogether to avoid the potential risk (especially since there is really no benefit).

    FYI, ITP had a similar trigger-level for the warning flash on their multi-power lights (as you can tell in the traces above). I am happy to report that based on customer feedback, they have removed it completely on their latest batch of C7/C8/C9 lights. I hope Olight will consider doing the same.

    UPDATE: MattK informs me that upon further investigation, it seems the issue for most of the M20 owners who have reported a problem with the low voltage flash have been attributed to over-lubrification (i.e. migration affecting the current path). That sounds believable to me, as I have observed that excess lube can wreck havoc on lights with complex circuits. That said, Olight appears to be listening to feedback as they have told Matt they are removing the feature from future production runs. Good job!

    General Observations

    The M20 is a quality light. Build is top notch, with lots of signs that care and consideration went into its design and construction.

    The regular Olights are all well made lights, but I find the M20 definitely ratchets things up a notch or two. Although bulkier than the slimmer design lights in this class, the M20 is still smaller than I expected - and smaller than all my dedicated thrower lights.

    I particularly like the new sequence of Lo > Med > Hi > Strobe (compared to the Hi to Lo sequence on regular Olights). Personally, I would prefer to have Strobe hidden off somewhere other than the main sequence, but this arrangement is certainly not bad.

    But the inclusion of a true Lo output level is an extremely welcome addition. Typically, current-controlled lights that are optimized for specific output levels (like Fenix and Olight) are more output/runtime efficient than continuously-variable PWM lights. But PWM-based lights are capable of much lower output levels, thus having the ultimate low output runtime advantage. The M20 definitely has the best performing low mode I've seen on a classic circuit (>3.5 days on 2xRCR - at that performance level, I'd expect a good week on 18650!).

    I am also quite impressed with 18650 performance on max. Simply put, the M20 is the brightest multi-power light on 18650 that I've tested to date. Coupled with its decent semi-regulation - maintaining at least 80% of its initial output before falling out of regulation - this makes the M20 a clear winner (see the first runtime chart again for a comparison of all batteries on max).

    Although many decry the lack of completely flat regulation on 18650 in multi-power lights, this is the apparent trade-off required to bring higher voltage level support. If you want perfectly flat regulation on 18650, you are going to have forgo 2xRCR (and potentially even 2xCR123A). Besides, semi-regulated 18650 performance is typically more efficient than full regulation, and provides a long "moon-mode" before triggering the built-in battery protection circuit. The M20 is great performer on all batteries, IMO.

    With its evident build quality, well-spaced output levels, and excellent runtime performance, the M20 is a strong contender in the "tactical" 2xCR123A/RCR/1x18650 class. As always, it all depends on what feature set matters the most to you - but the output/runtime performance of the M20 is certainly excellent so far in my testing.

    ---------------------------

    UPDATE 4/25/2009: Matt at Battery Junction has provided me with the new Olight filters for the M20.



    First thing I noticed is that these are not cheap colored pieces of plastic. They appear to be actual ground glass, and have an anti-reflective coating that gives them a strong complementary pink/green hue when looked at from an angle. To illustrate my point, here's a flash effect from a steep angle:



    No, I have not reverse the filters - red is still in the middle and green is at the end. The AR coating gives you this complementary shine.

    Olight has released separate filters for the M20 and the small T-series light, but I believe construction is equivalent.



    Note the soft-plastic filter cap has grooves specially cut to fit the scalloped edges of the M20's stainless steel bezel ring. The filter/diffuer covers are a good snug fit, as there is some give in the rubberized material of cover. Very little light sneaks back out around the head.

    Here's how they look against a white wall. All pics are at 1/25sec, f3.2, white balance locked to daylight, M20 on max on 1x18650.

    Control shot of the M20 (note the slightly greenish hue of the R2-WH tint):


    Now with the diffuser:


    Green filter:


    Red filter:


    As you can see, the red filter seems to block a lot more light overall. This is likely due to the fact that LEDs output a lot less in the red wavelengths than they do in the blue and yellows (so there is less light overall once filtered for those wavelengths).

    Interestingly, there is a complementary color effect right around the bezel with the filters (likely due to the dual AR coating). Here's some close-ups to show you what I mean - lights are lying on top of a white cardboard box:






    Final word: I'm very impressed with the qualiy of these filters and diffusers. They are well-made, and certainly well suited for the M20. Good job.

    Thanks for another very helpful and insightful review. It is good to see more lights scoring so well on build quality. The output/runtime graphs here are very impressive too.

    They will need to act promptly to implement a fix for the low-voltage flash problem.
    Resistance is futile...

    Looks like Olight is listening! Just heard from MattK who informs me that Olight is removing the feature from future production runs.

    Apparently, it seems the issue for current owners who have reported a problem with the low voltage flash has been attributed over-lubrification affecting the current path. That sounds believable to me, as I have observed similar lube effects on other lights with voltage sensors (i.e. if lube migrates to a contact surface, all bets can be off). A thorough cleaning should hopefully solve the problem for those experiencing it.

    Good that they are removing the low voltage sensor - should prevent any problems for future runs.

    Excellent review here, Selfbuilt.


    As always ! ! !







    BTW, my Olight M20 also has the LowBatteryFlash problem,
    even though i have carefully removed the Lubrication.


    Even painstakingly treated it all with DeOxit and ProGold.





    Sometimes, just shaking the light is enough to cause the Blinking.


    I'm certainly glad to hear that Olight is gonna' remove that "feature".





    Because, this IS a wonderful flashlight !

    Sorry to hear you are still having problems, but I agree with you on all the merits of this light. Hopefully your dealer will take of you.

    FYI, I've just updated the main post with some additional comments. The runtime on Lo on 2xRCR has just terminated, at a little over 3.5 days! Frankly, at that level of performance, I'd expect a good week on 18650 (and no, I won't be testing that in my lightbox ).

    I've also been playing with the custom-designed holster a bit. It's definitely high quality, and I like the side attachments to carry extra cells/magazine. The light is also easy to draw from the top without opening the velcro flap - at least without the grip ring installed (can still be done with it, but more resistance). Not sure if I would really use it for everyday carry given its size, but likely pretty good for those who carry a lot of equipment on their person.

    Hi selfbuilt,
    excellent review, as always

    Just one point that bothers me:

    Runtimes on med:
    Duracell CR123A = 8hr 52min
    AW Protected 18650 = 7hr 48min

    I'm not an expert at all, but I would have expected much longer runtime on 18650 than on CR123A...

    Why? 18650 contains roughly the same amount of energy as 2xCR123.

    Actually, I agree with both you!

    When I first saw the results, I had the same subjective impression ... shouldn't the runtime on 18650 be longer than 2xCR123A on Med? But then I thought: if anything, isn't the capacity of 2xCR123A slightly higher than your typical protected 18650?

    So why did I (and Minilux) expect the results to be otherwise? I think the answer is that we are used to looking at MAX runtimes. In multi-power lights, that means two things: on 18650 the light is running direct-drive (which is more efficient than fully regulated), and the light puts out considerably less output over most its run than the regulated 2xCR123A. As such, we are used to seeing much longer runtimes on 18650 relative to 2xCR123A - but we are comparing apples and oranges (i.e. a lower output, and in a more efficient state)

    When you now switch to looking at FULLY regulated Med modes on both batteries (i.e. apples to apples), the greater capacy of 2xCR123 reveals itself.

    That analysis is backed up if you look at my Thrower round-up review. There you'll see several examples of long 18650 runtimes in multi-power lights on max - but these are all cases where the output on 18650 is direct-drive and considerably less than the 2xCR123A output (i.e. what we are typically used to seeing). However, in the one example (Tiablo A8) where both 18650 and 2xCR123A are similar in output and fully regulated on max, you'll see 2XCR123A outlasts the 18650 - as seen here on Med.

    This is actually an interesting example illustrating how the weight of our experiences skews our perceptions (i.e. we are used to seeing longer 18650 runtimes, without considering the different output/runtime patterns). Interesting how the actual data can challenge the subjective associations we tend to make.

Also, 2 CR123A's have about the same capacity as 1 18650 but an 18650 has lower internal resistance so in high discharge rate applications the 18650 will outperform the 2 CR123A. In medium mode on the M20 the discharge rate is lower than the 'advantage point' of the 18650 so what you see is the slightly higher watt hours (in this case) of the 2 x CR123A's coming into play - with the caveat that there are higher capacity 18650's that can beat 2 CR123A for total WH. There are higher capacity premium 18650's available but none that are protected that I am aware of; also the protection circuits of the cells varies and some, in an effort to better protect the cells, have cut-off points with an overhead that cuts them off above the cells cut off point.

    There are a few threads that will be left exposed should the grip ring be removed - it's not really an issue, you don't feel them when using the light. We have mentioned to Olight that it would be nice to have a ring to cover them and it is under consideration for the future.
    A good description Matt. We don't usually discuss lights in terms of watt hours around here (although maybe we should ), but it is important to remember how the internal resistance of different batteries will produce different outcomes at different drive levels (also different heat patterns, etc). The point about variability in protection level cut-offs is also good to keep in mind. Personally, I prefer to stick with 18650 and keep CR123As around for back-up purposes, but whatever floats your boat.

    On the point about the grip ring - yes, I have observed the same (i.e. exposed threads with it removed). The threads are fully anodized and not very deep, and so are not too noticeable, but some sort of cover would be nice. I just leave the grip ring installed (although this does retard pulling it through the holster flap opening somewhat).

    Yes, all my Duracell, Energizer and Surefire CR123A have it - but the lighting in the picture is making it look more pronounced than it is in real life.

    Great review as always Selfbuilt! A question if you don't mind;

    It doesn't look like it comes with a sleeve to replace the finger grip ring. Does this just leave exposed threads when it's removed? Any pictures with it removed?

    Also, Maybe more of a question for MattK, any word on when the revised run without the low battery indicator will be in the store, and will we be able to tell from the packaging or something that it's the new model?

    I'm liking a lot with this light and am having trouble deciding on this or one of the new JetBeams for a next light. Of course, there's always the option of "buy both"!

    Thanks for those very pertinent explanations selfbuilt. You're right, looking back at the runtime graph for med on 18650 and 2xCR123 I realize that - contrary to high - the M20 seems to be fully regulated on both battery types, thus giving longer runtime to the overall higher capacity batteries, which are 2xCR123 in this case.

    So it might be a good idea to keep both models of batteries handy in the M20-holster, having the choice either for longer high runtime (with declining brightness) with 18650, or longer med - and low - runtime with 2xCR123

    Man, I am just this close to ordering one if these and I really do not even have the money! The high quality holster is a really nice and appreciated touch, I do not like getting a .39 cent holster with a $50-$100 light so great job to Olight! Also the listening to the customers with the power issue is nice too, my only wish left is for a sleeve to cover the threads when the tac ring is removed.

    I hope they come available to people that already own one just in case I cannot resist and end up ordering one!

    What are actually the advantages of choosing the M20 Warrior Premium Edition over the standard M20 Warrior version ?

    What is actually the big advantage of buying the R2 Premium version over the standard Q5 version ?
    Numberswise they seem quite comparable,

    The Premium R2 version is slightly brighter; that's the only difference but for a lot of flashlight enthusiasts that's easily worth the price premium.

    Also the tint should be different. Premium version should have WH tint which is warmer.

    extra clear plastic tailcap boot cover.
    Want to add that the spare clear plastic tailcap actually glows in the dark - it glows a soft Blue instead of bright green..

    You guys have convinced me - Order put through to Battery Junction earlier today for M20 Premium. Bloody CPF gonna cost me lots of money!
    So many lights, so little money (cause I spent it on lights). I'm not afraid of the dark, the dark is afraid of ME!

    Hi selfbuilt,

    just saw the review of the M20 on light-reviews.com:

    http://www.light-reviews.com/olight_m20/

    I'm very astonished about the differences to your review:
    * lux measuring at different bat types show much more variation between 18650 and (R)CR123
    * runtime at high are about the same, those on med show notable differences (e.g. AW 16340 750mAh: 4:43/3:22 ... a whole hour!)

    But what really bothers me are the runtimes on low:
    while you get about 84 hours on AW 16340 750mAh, light-reviews claims just a mere 27 hours runtime, not even talking about those on 18650/CR123 which seem completely illogical to me

    I know that everyone's mileage may vary, but my impression is that in this case the differences are really way off

    Do you - or anybody else - have an idea where these differences may come from?
