Wait, Olight makes 1AA baton lights? How did I not know that.... I gotta look into those. Or was that only for that model in the past?
The S15 is an older model.
I have one. It is ok, but personally quite a lot of design flaws.
On an AA the output is pretty hopeless tbh. Really very badly performing.
On a 14500 the output was ok, but runtimes are so low to the point of it not being worth using with Li-ion. As it would drop out of regulation and dim. If you only used it on low modes it was ok, but then an Eneloop would likely serve you better.
I found it ran best on 2AA (Eneloop, would never use alkaleaks). And would be able to sustain output and regulation way better than a 14500. The snag here is, the S15 has a tailcap magnet, but it is not strong enough to hold the Baton when in 2AA mode unless it is pointing down. At an angle or horizontal it would just fall off.
The electronic switch is also of the type that will activate in your pocket very easily, so made it a poor EDC light. Also being an electronic switch, it is no good as a backup light either unless you physically lock out the tailcap. It will just drain the batteries otherwise.
Output and beam profile were pretty good however, despite being a horrid cool white tint.
All said and done, I don't think I've used mine in about 3 years now. Which likely says something to the real world issues in making use of such a light.
