UPDATE October 12, 2012: Olight has revised the tailcap design, which now features a removable magnet and spring. Scrol down for details
The S10 is the latest addition to the Olight Baton series of flashlights a series that look like, well, batons . The S10 is the smallest member of the family, and takes one CR123A or RCR cell. For a comparison to the other Baton lights, see my S35/S65 and S80 reviews.
Let's see how it compares to others in its respective class as well as what has changed from its larger Baton predecessors.

My other Baton-series reviews were often based on early samples, so full retail packaging generally wasn't available. Olight did send me a shipping S10 for this review, so you can see the compact packaging up above. Olight includes a belt clip (attached), simple lanyard strap, extra o-rings, split ring, and manual.

Note: Olight initially sent me an engineering sample to test, so many of the pics above are from that original sample. Externally, the final shipping version differed only in a few body labels, shown in the close-ups below.
UPDATE October 12, 2012: Labels have changed again - on the currently shipping tailcap with the removable spring, there is no longer the "N" or "S" label on the tail. Scroll down for details
The S10 is quite petite for the class. Overall build is similar to the earlier cylindrical Baton lights, but with a few upgrades. Like the other Batons, the S10 features black anodizing (matte finish now), with bright white labels. Although still without typical knurling, the fine ridges of the other Batons has been replaced by a raised checkered pattern on the S10. With the pocket clip attached, I'd say grip is reasonably good.
New to this model is the pocket clip. Although only of the clip-on style, it seems to hold onto the light fairly securely. It is also reversible, allowing you both bezel-up or bezel-down carry options.
Light can tailstand, and there is a split-ring/lanyard attachment hole on the side of the tail cap. There is also a fairly strong magnet on the tailcap, allowing the light to stand firmly on any metal surface. In fact, on the original tailcap, this the magnetic pull is so strong that it could even hold onto the battery through the spring, as shown here:
UPDATE October 12, 2012: Note that this is no longer the case with the currently shipping tailcap. The removable spring is no longer in direct contact with the magnet, so magnetic pull through the spring is greatly reduced. Scroll down for details.
As before, the light uses an electronic switch, located near the head. There is a textured power logo on the switch now (the earlier model Batons were smooth white). Also, there doesn't seem to be a low-voltage warning LED under the switch anymore (at least, I saw no evidence of a sensor on my sample).
Like the other Batons, the S10 uses square-cut screw threads as before but now anodized for tail lock-out.
As before, the light has a flat stainless steel bezel ring with a red o-ring, and a textured (orange peel) reflector. The reflector isn't very deep, so I would expect a wide spill beam. Emitter was well centered on my sample.
Tailcap Design Update (October 12, 2012):
As shown above, the original batch of S10s had a non-user-removable magnet. More recent shipping versions have a modified spring design that allows the user to remove the magnet. For those of you with the original tailcap, you can contact your dealer to obtain a free replacement version with the removable spring. Alternatively, Olight is offering a free diffuser wand to those with the original tailcap who are happy to keep it. More details on this "Compensatory Scheme" are available on the Olight website.
You can tell which version you have from the pics below (original shipping is on the left, current version is on the right).
There is a Olight instruction manual on their website, which will explain how to swap out the magnet in the current design. I also have prepared a video showing you how to do it. As always, you are likely to want to run this video at the higher 720p resolution for more detail.
In addition to the ability to now swap out the magnet, there are two signficant factors I've noticed with the new tailcap design (explained in the video). The first is that the new spring design introduces a slight rattle when handling the light (with the magnet installed). Secondly, while the magnetic pull is just as strong out the back of the tailcap, you can no longer pick up a battery by the spring on the inside of the cap.
Both of these are likely due to the spring not being as deeply/securely fastened inside the tailcap (i.e., it no longer seems to make direct contact with the magnet, hence the reduced magnetic pull through the spring). The rattle issue disappears if you swap the magnet out - the bundled o-ring is thicker than the magnet, and makes direct contact with the spring (dampening any movement). If you want to keep the magnet installed with the new design, I'm sure you could fully dampen the rattle with a thinner o-ring inserted under spring. An extra thin o-ring from a 1xAAA keychain light would probably do the trick.
Like the other Baton lights, the S10 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 - Med, in repeating sequence. This differs from the other Baton lights which were Lo Med Hi (i.e., in this case, the S10 steps down after stepping up in outputs). 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.
Note that if you memorize the light in Med, when next you turn it back on, it will always be in the first Med in the sequence. In other words, the next level in the sequence will always be Hi when re-activating in Med mode from Off.
The S10 features a new innovation a "Moonlight" low mode that is directly accessed from off by a sustained press of the switch. This is an excellent adaptation, as you can always turn the light on in the lowest possible mode if you want. Mode cycling and memory works as before, once on.
There is still a "hidden" strobe mode, accessed by double-clicking the switch when on. Double-click again to return to constant on.
The S10 no longer features the typical Olight "soft lock-out." Holding the switch down when on simply continues cycling between output modes indefinitely. To lock out the light, I recommend you twist the tailcap.
For information on the light, including the build and user interface, please see my new 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.
There is no sign of PWM that I can see, at any output level I presume the light is current-controlled, as claimed.
Strobe is a standard "tactical" high frequency strobe, measured at 9.7 Hz.
As the switch is an electronic one, a standby current drain is always present when a battery is installed.
I measured this standby drain at 5.7uA for 1xCR123A, and 5.8uA on 1xRCR. For a standard 1400mAh CR123A and 750mAh RCR, that would translate into over 28 years and 14 years, respectively, before a battery would be fully drained. Hardly a concern although I do recommend you lock out the switch at the tailcap to prevent accidental activation.
And now, the white-wall beamshots. All lights are on Max output on the identified battery type. 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.
1xRCR (AW Protected 750mAh) Li-ion Comparison:
Beam pattern is as you would expect for a XM-L light with this size textured reflector a fairly big hotspot and decent sized spillbeam. Scroll down for full output details in my tables.
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).
The S10 has a balanced overall output pattern, with a good spacing of levels. Reported Olight ANSI FL-1 output and beam intensity specs seem accurate.
The S10 has a somewhat distinctive step-down pattern on Hi: after 5 mins, the light steps down to a slightly lower level but gradually, over a period of two minutes. This differs from most lights that have an abrupt step. As a result, you are not likely to be able to perceive the gradual dimming here.
Efficiency seems excellent on the S10, especially on primary CR123A.
UPDATE October 10, 2012: Here is a summary table showing what my ANSI FL-1 lumen estimates are for the S10:
As you can see, my results are very closely in-line with Olight's published specs on 1xCR123A. Max output increased slightly on 1xRCR, but the difference is barely noticeable in real life.
Baton lights all use an electronic switch, and therefore require a small stand-by current when fully connected. However, you can lock out the S10 at the tailcap, and the standby drain is so low (<6 uA) as to be negligible on the lifespan of the battery (i.e. many decades). But note that the S10 no longer uses the "soft" electronic lock-out feature of its predecessors.
Mode sequence has been changed from a consistent repeating Lo > Med > Hi on the other Baton lights to a repeating Lo > Med > Hi > Med. Originally, I felt this would could be potentially annoying (i.e., you may have forgotten where it is in the sequence after leaving it off for ahile). But on further testing, I see now that it always comes on in the first Med in the sequence (i.e., Hi will always follow Med after a re-activation).
There is no low-voltage warning sensor on the S10, as there was on the S35/S65/S80 (previously located under the power switch).
The S10 is a nice addition to the Baton series of Olight lights.
I like most of the updates to this model, including the good clip (reversible), keychain attachment point, and revised knurling. The S10 is quite comfortable to carry and use, with good ergonomics in my opinion. Personally, I'm not crazy about magnetic tailcaps but they do have their uses, and some people really like them. In this case, it is certainly strong enough to hold the light horizontally off a metal surface. And magnets can always be permanently disabled by the local application of high heat. In this case, a typical butane lighter was only able to diminish it slightly on my sample, but as suggested in the discussions below, a soldering iron would be a lot more effective (and certainly safer).
UPDATE October 12, 2012: Olight has revised the tailcap design, which now features a removable magnet. See my updated build section for an overview and video on how to swap out the magnet.
The user interface updates are generally goood the "hidden" Moonlight mode accessed from Off is brilliant, and a great addition to the interface. The Lo > Med > Hi > Med is a little unusual, but the light always re-activates on the first Med mode from Off (i.e., Hi will always be next in the sequence upon re-activation).
Nice to see they have kept the standby current at a completely negligible low uA current. I am not sure why the "soft" electronic lock-out mode was ditched on this model, but I don't really miss it given that a physical lock-out is now possible at the tailcap. This is my preferred way to prevent accidental activations anyway.
Output mode spacings remain good better in fact, with the new Moonlight mode on the S10. And the performance of the light is excellent in my testing, in keeping with the good current-control circuitry (i.e. very long relative runtimes). It is a particularly thoughtful idea to have the gradual drop-off in the Hi mode step-down, so that you won't notice the dimming.
The S10 is a nice update and extension to the Baton line of lights. I like most of the light tweaks and updates, and am impressed with how Olight handled the magnetic tailcap issue (i.e. offering free updates to those with the original permanently-installed version). The S10 stands out as another good potential option in the defined-level 1xCR123A/RCR space. A very strong contender.
S10 was supplied by Olight for review.
