Thread: Olight S15 (XM-L2, 1xAA/2xAA/3xAA) Review: RUNTIMES, BEAMSHOTS, VIDEO + more!

  1. #1

    Thumbs up Olight S15 (XM-L2, 1xAA/2xAA/3xAA) Review: RUNTIMES, BEAMSHOTS, VIDEO + more!

    Warning: pic heavy, as usual.





    Olight has updated their Baton S-series lights with a new model – the 1xAA S15. There are a number of build updates from the earlier S10 and S20 lights (although those models are also getting a facelift for 2013 – wait for my upcoming review of the new versions of those lights).

    A nice feature of the new S15 is that it comes bundled with a 2xAA battery tube extender (and can even support 3xAA, with two extenders in place). Here's how it looks in 2xAA configuration:





    From the way the light is marketed, you would be excused for thinking it is primarily a 1xAA light (with the option for extra cells). But based on my experience in this review, I tend to think of it as a 2xAA light that can be shortened … the reason for this distinction will become clearer as we go through all the testing results.

    Manufacturer Reported Specifications:
    (note: as always, these are simply what the manufacturer provides – scroll down to see my actual testing results).

    The S15 comes in packaging that is very similar to the new Olight O'Pen (aka Foursevens Penlight). Inside the clear plastic container is the light, extra o-ring, a simple wrist lanyard, AA battery extender, and manual. There is also an overview of specs on the bottom and back of the packaging.

    As with the S10 and S20, the S15 is quite petite for its class. Overall build is similar to these earlier lights, with black anodizing (matte finish) and bright white labels. Although still without typical knurling, the S15 shares the same raised checkered pattern as on the S10/S20. With the pocket clip attached, I'd say grip is reasonably good.

    The pocket clip is comparable to the earlier models, although longer than the original S10. It similarly seems to hold onto the light fairly securely. I personally like it, as you can clip it on you in either orientation (i.e., bezel-up or bezel-down carry), although it might be rough on clothing given how tightly it fits.

    Like the S20 (but not the original S10), there is now a spring in the head. However, there is also a plastic disc surrounding it, which acts as reverse-polarity protection feature (i.e., flat-top cells won't work in the light).

    Like the other Batons, the S15 uses square-cut screw threads (anodized for tail lock-out, like the S10/20).

    Light can tailstand, and there is a split-ring/lanyard attachment hole on the side of the tail cap as before. The tailcap in fact seems identical to the S10/S20, with the same removable strong magnet (i.e., firm enough for the light to stand horizontally off any vertical metal surface). I previously prepared a video of the S10, showing you how to swap out the magnet in the tailcap:



    They seem to have improved the design, as I no longer notice any rattle on the tailcap (as I did on the S10/S20 with the magnet installed). As before, the light uses an electronic switch, located near the head. However, the user interface has been updated from the earlier S10/S20 (see below). Also, the low-voltage warning LED that was present under the switch of S20 is gone now (i.e., there is no such indicator om the S15).

    As before, the light has a flat stainless steel bezel ring with a red o-ring, and a relatively smooth reflector. One difference – the lens anti-glare coating is not as pronounced now. This is actually good news, as I (and others) had found that the anti-glare on the S10/S20 lens was contributing to the relatively greenish tint.




    The S15 has been updated with XM-L2 Cool White emitter (which was well centered on my sample). Note that the S10/S20 are also receiving updates for 2013, including the same emitter and user interface described below. The reflector of the S15 remains relatively smooth finish (like the older S10/S20 lights).

    User Interface

    The S15 interface has been updated from the previous S20. FYI, the new 2012 XM-L2 editions of the S10 and S20 will feature the new interface described below.

    Like the other Baton lights, the S15 uses an electronic switch for on/off and mode control. As before, a quick press and release turns the light on.

    Mode switching is controlled by holding down the electronic switch. The light will cycle between Lo – Med – Hi, in repeating sequence. This has changed from the earlier S10 models. As before, simply release the switch to select your desired mode. The light has mode memory – if you turn it off/on, the light returns to your previous level.

    The S15 also features the ultra-low "Moonlight" level, as the S10/S20 did. You access this mode directly from off by a sustained (>1 sec) press-and-hold of the switch from off. This is a nice feature, as it means you can always turn the light on in the lowest possible mode if you want (i.e., no matter where you memorized it before). Mode cycling and memory works as before, once on.

    Note that the S15 has a revised "soft lock-out" mode now - if you hold the switch down from off for >2 secs, the light shuts itself off (i.e., after one second of the Moonlight mode). You will not be able to use the light until you unlock it (by pressing-and-holding the switch for >2secs again). Note that this means that if you want Moonlight, you must release the switch before the lock-out takes effect (hold the switch between 1 and 2 secs).

    There is still a "hidden" strobe mode, accessed by double-clicking the switch when on. Double-click again to return to constant on.

    The low battery LED indicator below the switch is gone now, likely due to wider voltage support (i.e., the S15 supports 1xAA, 2xAA and 3xAA).

    UPDATE NOVEMBER 4, 2013: As one of the viewers on my video page commented, there is a short-cut to jump to Hi from off: double-click the switch from off. Note this doesn't work if your last memorized mode was Moonlight, but it does work for the other modes.[/I]

    Video:

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



    Video was recorded in 720p, but YouTube typically defaults to 360p. Once the video is running, you can click on the configuration settings icon and select the higher 480p to 720p options. You can also run full-screen.

    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.

    PWM/Strobe

    As always, there is no sign of PWM at any output level – The S15 is current-controlled like its predecessors.



    The strobe is a fairly typical fast "tactical" strobe, of 9.7Hz frequency (as before).

    Standby Drain

    As the switch is an electronic one, a standby current drain is always present when a battery is installed. However, it is so low that I was not able to get a stable reading with my DMM. When initially connecting, I got a brief ~1uA current, which then dropped down to a <1uA current. At that level, it would take forever to drain a battery (roughly speaking).

    Beamshots:

    For white-wall beamshots below, all lights are on Max output on an AW protected 18650 battery. Lights are about ~0.75 meter from a white wall (with the camera ~1.25 meters back from the wall). Automatic white balance on the camera, to minimize tint differences.

    1xAA Sanyo Eneloop NiMH













    As you can tell above, the S15 is not driven as hard on 1x standard batteries as some of the competition.

    1x14500 (AW Protected 14500) Li-ion













    The S15 is certainly brighter on 1x14500, but again not at the top of this class range.

    2xAA Sanyo Eneloop NiMH













    Hi output on 2x sources is certainly more in keeping with other recent lights in this class, although the S15 remains relatively less throwy than most. Scroll down for detailed output and throw measures.

    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 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 Chart:

    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).






    As you can probably tell from the above, there is remarkable consistency in the lower output modes, across all battery types. Where the light differs is in its response to different batteries on the Hi mode (scroll down for my lumen table). Throw is about what you would expect from a light this size.

    To further explore the differences in max output across battery sources, here is my summary lumen estimates table:



    Although I didn't include it in the table above, note that 1xL91 Lithium has a lower Hi mode of ~130 estimated lumens. 2xL91 is in the same range as the other 2x battery sources. 2xAlkaline is similarly no different from other 2x sources.

    Note that the above is not a surprise to me – it all comes down to voltage, and the ability of the cells to provide stable power (for regulation) at a given level. 1xL91 is frequently lower in output, due to its lower voltage. 1x3.7V Li-ion 14500 is much higher voltage, therefore pretty much indistinguishable from 2x sources.

    UPDATE AUGUST 14, 2014: I just received another S15, that I personally purchased from an online vendor. There is apparently some variation in output levels on Moonlight/Lo among these lights, as indicated below.



    Please keep these results in mind, if you are purchasing the light with the intent of getting well-defined Lo levels.


    It bears repeating again that my estimated lumen scale is just that - an estimate, based on a consistent calibration of my lightbox. But even though the absolute value correlation is unknown, the relative comparisons still hold. All I can really say is that one light is higher or lower than another, by a certain relative percentage. So please don't get hung up on the absolute values of the estimates, or on small relative percent changes.

    Output/Runtime Graphs:

    Let's start by comparing the runtimes in 1xAA and 2xAA configurations, on all supported batteries:




    Ok, there is a lot if info to absorb up there. But there is one very surprising result – the S15 is considerably more efficient on 2xAA battery sources than 1xAA.

    Normally, 2xAA has slightly more than twice the output/runtime capacity of 1xAA. The reason it is not exactly twice has to do with how both the circuit and batteries deal with the differing discharge currents at different voltages. On lights that support both, you will generally see slightly more than twice the output/runtime capacity (often with much better regulation) on 2x sources vs. 1x.

    In this case, it is hard to give an exact efficiency difference, as the S15 is also considerably brighter on Hi on 2xAA compared to 1xAA sources (and by how much varies considerably across batteries). But if you compare the Med mode alkaline runtime (which is a consistent brightness on both 1xAA and 2xAA), you will see that the S15 2xAA alkaline has up to ~3.5 times the output/runtime capacity of 1xAA alkaline.

    Clearly, the S15 is optimized for 2xAA battery sources. The question is how does it compare to other 1xAA and 2xAA lights? In other words, is it a substandard 1xAA performer, a stellar 2xAA performer, or something in between?

    Let's start with 1xAA:











    Again, there's a lot of data up there, but one thing is clear – on 1xAA, the S15 is an excellent performer on its Med mode (relative to the competition), and a fair-to-mediocre performer on its Hi mode (i.e. closer to XP-G lights in output/runtime). The one exception is Hi on the higher voltage 1x14500, where it performs much better (as expected).

    How about 2xAA comparisons?








    On both Med and Hi, on 2xAA, the S15 is an outstanding performer.

    Taken together, these results show that the S15 has an incredibly efficient circuit at all levels - except for standard batteries (NiMH, alkaline, or L91) on the Hi mode with 1x sources.

    To summarize all that, the S15 is currently one of the top output/runtime efficiency performers in this class. It is just the Hi mode on standard batteries on 1xAA where you get performance comparable to a XP-G-based light. Note that the S15 is also generally speaking a better performer on NiMH, L91 or 14500, compared to standard alkalines.

    If I can get my hands on another battery tube, I'll see how 3xAA compares.

    UPDATE AUGUST 17, 2013: Here's a revised NiMH Hi mode runtime graph, showing 3xNiMH on my original S15, plus a 1xNiMH runtime on the new sample I purchased.



    As you can see, there is a slight bump in output on the new sample. But what I find interesting is how the second extension tube on the first sample didn't really extend the runtime that much further past the 2xNiMH test. It really does seem like ~2.5-3V is the "sweet spot" for running this light (i.e., the outstanding performance of 2xAA).


    Potential Issues

    All Baton lights use an electronic switch, and therefore require a small stand-by current when fully connected. However, the standby drain on S15 was so low I couldn't even measure it accurately. This means you don't have to worry about draining your battery – although accidental activation is always a potential concern with electronic switches. You can "soft" lock out the switch electronically, and you can always physically lock out the S15 at the tailcap.

    All my earlier S10 and S20 samples had a noticeably green tint overall, especially so at the lower output levels. Part of this was due to the anti-glare coating on the lens, and part was due to the natural warm tint-shift that occurs at low drive currents. I am happy to report the S15 has a reduced anti-glare coating, which improves the situation slightly. However, you are still likely to notice a green-yellow tint in the hotspot, and blue-purple tint around the edge of the spillbeam periphery – but it is less pronounced than the earlier S10/S20.

    There appears to be considerable variation is the exact output levels of the Moonlight and Lo modes. As you will see in my revised result tables, a second S15 sample had only ~1/3 to 1/4 the output of my first sample, at these two levels.

    Preliminary Observations

    It is nice to see that Olight is continuing to update the build and user interface of the Baton series – as well as expand into the new battery configurations. The 1xAA/2xAA/3xAA S15 is a good addition to the family.

    The build changes are generally all positive. The anti-glare coating on the lens has been reduced from the S10/S20, which should improve the green-tint-shifting known on this series. The slightly revised user interface is good, with a multi-second lock-out mode now. The clip has improved in length from the original S10. And the always low standby current has been reduced even further – it's so low, I can no longer get an accurate reading.

    The one thing people might miss is the low-voltage warning indicator LED under the switch, which is gone now. But I could see why that would not be feasible in this light, given the wide voltage support (i.e., 1x, 2x, and 3x AA are all supported).

    The bundled 1xAA extension tube is nice touch, as you have the option to run the light in 1xAA or 2xAA configuration right out of the box (3xAA is possible with an additional extender). But as I mentioned in my introduction, this is one light that I see primarily as a 2xAA light (with the option to drop down to 1x).

    The reason I say that is the output/runtime performance of the light – it is simply outstanding on 2xAA sources, at all levels. On 1xAA, there is a definite drop in efficiency on Hi (although Med still seems excellent in my testing). Basically, the Hi mode is a top-performer on 2xAA, and a middling-to-below-average performer on 1xAA (i.e., on Hi, you only get the output/runtime performance of a typical XP-G light on 1xAA). Again, the light performs extremely well on Med, in all configurations and battery sources.

    One other thing to keep in mind is that the light also supports 1x14500 3.7V Li-ion, where you get the output level (and relative efficiency) of the 2xAA configuration. Oh, and if you aren't sold yet, you also get a top-of-class output level on 2xAA.

    As with the S10/S20 Baton lights, expect a generally floody beam pattern – with a wide spillbeam and relative broad hotspot. Tint has improved slightly over my older Baton lights, but there is still a noticeable green-yellow-tint shift at lower levels.

    The S15 is a nice example of the ongoing evolution of the Baton series of lights. Certainly a very strong contender in the slim and compact group of 1x/2x AA lights.

    This light was made for the T.I. crAA 14505.
    So 2-3 volts is where the circuit is most happy. 3-4v is 2nd favorite place, and doesn't like 1-2v

    Thanks for the review Selfbuilt - I just pulled the trigger on an order a few hours before you posted. I'm looking forward to the light as I'll usually run a 14500 or CRAA/14505 in it. As a low lumen enthusiast, I'm at least happy to see decent 1xAA (low voltage) efficiency on Med. and hopeful it will continue on Low and Moonlight modes which I expect to use most often. I'll probably run some side-by-side output/runtime tests at those lower levels with comparable lights like the D25A (X), QAAX, and SC52.

    Thanks for the review! I've been interested in AAs lately. I'm glad to see this light isn't much bigger than the Four Sevens mini I just bought. I love the extension tube option and support for 14500s. If it had a NW option I'd be all over it. I think this would be a good gift for the non-flashaholic.

    Well, it certainly isn't optimized for 1-2V on Hi ... but it seems to do fine on Med.

    Interesting thought about the TI 3V 14505 primary cells. The S15 should perform quite well on those.

    It is? Lol...you better call Olight and have them correct their advertisement...They claim the S20 still has one, although the switch is now different. And I did not think the S10 ever had a low batt warning in the switch....lol.

    Excellent review as always Selfbuilt, this is one crazy light. Wait till you play around with it on 3 cells...gets even stranger...from my pathetic testing anyways...

    I find it to be a fun light...don`t know any other way to put it...

    Ah, sorry if that wasn't clear as originally written. My point was that the original S10 I reviewed didn't have the low voltage LED indicator under the switch, but the S20 version did (both with translucent white covers). The earlier S35/65 had the LED indicator.

    The new 2013 XM-L2 models appear to be lacking the LED indicator, across the series. The S15 is just the forerunner of this change, so to speak.

    a)Aviation grade aluminum body, with anti-scratch type III hard anodizing. b)Updated the LED to the latest Cree XM-L2.
    c)There are four brightness levels: Moon-light, low, middle and high. These levels can be memorized when the light turned off; one special mode: strobe.
    d)Under off status, single click will turn on the light, quick double clicking can get high brightness, triple-click enable strobe mode, while long time press enable moon light. e)With strong magnet in the end of tail, the flashlight can be stick on the iron surface. The magnet can be removed and replaced by users.
    f)Invertible U-shape embrace clip. g)Stainless steel head ring, which can bear higher tensile impaction
    h)Flat tail cap, can be easily head stood. i)S10 has high efficient synchronous boost-buck driver circuit, perfectly support CR123A & RCR123A battery.
    j)S20 is designed for a wide input voltage and both 2xCR123A and 1x18650 are available.
    k)Time based thermal management, after lighting on high mode for 4.5 minutes, the output ramps down to 50% of high brightness to avoid overheating.

    My understanding/guessing, from the Olight literature/pictures, is the S20 still has a low batt warning in the switch, although the switch is now clear and don`t think it glows in the dark...the warning light might appear brighter. I have one on order, so guess I should say...I hope it does

    Awesome Review! been waiting to see info on the 2xAA setup and now I want to try it in 3xAA.
    Had mine for about two weeks and love it! are you doing the New S20?

    Hi Selfbuilt. Thanks for another great review. I just bought the Olight S15 and it should arrive by the end of the week. This is my first foray into modern LED flashlights, so I am definitely a novice in the subject. Since I plan to use the S15 only in a 1xAA Energizer Lithium primary format (occasional use, not daily), would you say that there is a better light out there for this format? I was looking at your output/runtime graphs and I noticed that there are 2 outstanding lights using standard AA, which is the SC52 and Lumintop ED15. Out of all of the lights that you compared, the Lumintop was the only one that I didn't look into/hear about in my flashlight research. It was a nice surprise because the exposed button (accidental ons) and hold mode switching are the only two things that I don't like about the Olight; and the Lumintop ED15 addresses both of those preferences.

    Given my use of a 1xAA Energizer Ultimate Lithium format, would it be a significant difference in output/runtime between the Olight S15 and the Lumintop ED15? I'm prepared to eat the return fee (back to GoingGear) to pick the Lumintop if it is better for me. Thank you very much.

    Yes, I've just double-checked, and it looks like the new S20 will indeed continue to have the low-voltage LED indicator under the switch (although the switch material has changed). It is just the S15 and S10 that continue to lack this feaure (and have a the new blue-style button).

    I will be able to confirm when the shipping versions of the 2013 XM-L2 S10 and S20 arrive.

    Yes, the S15 is not a particularly good performer (on Hi) on 1xL91 lithium - although it is outstanding on 2xL91, and should be fine on its medium modes.

    As for those other lights, I would suggest you pay careful attention to the user interfaces and discussion threads. For example, the Lumintop ED15 which I reviewed lacked any form of mode memory. But according to a report in the thread, they have release another model (with the same model number) that uses visible PWM with mode memory. This would be expected to greatly reduce the efficiency of the light.

    I am surprised the S15 XML2 w/14500 doesn't hit the level of the S10 XML w/16340. Is it the fact that they had to accommodate so many possible voltages, i.e. - 1.2, 1.5, 2.4, 3.0, 3.7?

    I actually prefer that my lights do not have memory, because I know it will always start in low.

    Yeah, the problem is that I won't be using it in a 2xL91 format. Your estimated output for the S15 on 1xL91 is roughly 8.4/110/130. That sounds like terrible spacing for my needs, so I think I will return it. It looks like the Lumintop will have very good run times and output spacing using 1xL91. Thanks for the heads up regarding the different models of the Lumintop. There aren't too many dealers, but I know HKequipment carries them. I hate to keep asking you personal questions, but would you say that the Lumintop ED15 is better at running Energizer Lithiums than the Xeno E03 (v3)? I have read both of those reviews but it isn't exactly clear for L91s. I know you recommend the Xeno E03 in the recommendations section on your website.

    I would presume so - the S15 is regulated so that all >2V configurations are regulated to a common set level.

    I would just make sure you are getting the flicker-free, constant-current version of the ED15 (sans memory). I haven't tested the Xeno on L91, so can't comment on its specific performance. I would choose based on your preferred user interface.

    Ok...one more. Would you recommend the Zebralight SC52w on lithium primaries? From your review, they seem to do quite well. Does your memory match that? The only thing that kept me back from buying the Zebralight in the first place was the bad customer service stories and the green tint issues. Otherwise, it seems to be among the most suggested 1xAA light.

    The SC52 series has excellent performance on all standard cells, L91 included. I don't have any first-hand knowledge of the tint in the SC52w, but my previous "w" versions of Zebralights were all pretty decent.

    My s15 just arrived today. Overall, I really like the light with one major exception. My Keeppower 14500's will not work in this light. It appears the button on the battery is not quite long enough. This is a shame since I have more coming for this particular light!

    That is possible, given the protective disc around the spring. But it is also possible that your 14500 is too long to allow the tail cap to screw down fully. That can happen with some protected cells.

    EDIT: It seems like the issue is the top - the plastic disc in the head does serve as reverse-polarity protection.

    Well, mine came in today, and just on initial impressions, I'm really disappointed :-( I think this will be my first return.

    Appears as if mine's subject to some serious sample variation from what I've read of other user reports, and I can usually reconcile pretty well with Selfbuilt's results, although I choose to use the much conservative lumen scale employed by 47 Quarks and ET D25s.

    CRAAs don't work, button tops are too flat for the physical polarity protection on this light, although maybe a small disk magnet would fix it.

    Mine also buzzes (inducer whine?) on low, but it's not too bad - you have to put your ear up to it to notice.

    Mine has some weird behavior when activating memory (most noticeable on the lower modes), but only after its been sitting for a couple of minutes - there's millisecond where it's like it can't decide which mode to start in and flickers before settling on the memorized mode. Not really noticeable on 1xNiMh, or on the higher modes, but it becomes a low output pre-flash with a 14500 on moonlight.

    Mine's a little greener than my other Gen 2 XPGs and XMLs, but not as green as my SC52.

    What really bugs me though is that the low modes are so far off spec (ML and low tend to be my often use modes on my lights) - I thought my SC52 was bad being off 2-4x.... this S15 is off by 3-10x. Can't break out my light meter now, but I'm guessing my moonlight and low are ~ 0.05 and 2 lms respectively. The medium and high modes seem about right by eyeball, though. Anyone else notice this?

    Here's a cellphone side by side with a couple other lights and their (Spec) vs Meter readings - L to R (shown B&W):

    Top
    QAAX (0.3) 0.3.... (Meter calibrations done from QAAX 115 lm mode)
    T10 (0.09) 0.13
    SC52 (0.34) 0.08
    S15 (0.5) ?0.05?

    Bottom
    QAAX (2.7) 3.0
    T10 (9) 13.0
    SC52 (2.7) 1.5
    S15 (7) ?2.0?

    If you look closely, there isn't really a spring in the head of the s15. It's simply flat wire in a spiral. Also, mine has a black washer in the head most likely for polarity protection so a button top cell is required. I also bypassed the tailcap so the length of the button is definitely the issue.

    Interesting, it is hard to gauge the height of the spring, since the head doesn't open. But I have just tried a TI CRAA 14505, and it is unable to activate without a magnet on the positive contact. So it does seem like that disc provides reverse polarity protection.

    My S15 have a horrible whine in either moonlight or low mode with either 1x NiMH or 2x NiMH. No noise at all when I use a 14500. Weird...

    Not really - inductor whine tends to be highly specific to a given drive level and voltage source. It's basically believed to be a resonance effect, and it's hard to guard against in multi-level lights that support a wide voltage source. Often you will find it only on specific levels on specific batteries.

    On my shipping S15 sample, I can hear very faint hum at the Lo level only, on 1x or 2xNiMH - but only if I hold it right up to my ear in quiet room, and even then it is very subtle. On my pre-release S15, I can detect it on Lo and Hi (but not Med or Moonlight), and its louder on the Hi mode. On neither sample was it noticeable to me in actual use. But it does sound like this is variable, given the other reports here.

    Thanks for the S15 review. (...) Is it true that your Armytek Partner XP-G light on Eneloop is brighter than SC52 XM-L U3 on Eneloop? 300 lumens woot!

    Isn't that sensational?

    Erh. Thanks again
