Olight S2 Baton LED Flashlight

Amazing Output

Experience where power meets portability with the S2 Baton LED Flashlight, Olight's newest addition to the Baton Series. Equipped with a CREE XM-L2 U3 LED, the S2 is able to produce up to an astounding 950 Lumens of illumination while in Turbo Mode as well as 4 other constant brightness options ranging from 400 Lumens all the way down to a 0.5 Lumen Moonlight Mode. Designed to help conserve power, the S2 automatically dims the Turbo Mode to 50 percent brightness after 2 minutes to extend battery life. The flashlight is then able to run for an additional 170 minutes in Turbo Mode after it dims and can run its Moonlight Mode for up to 60 days straight on a single charge while using an 18650 battery.The S2 even features a special Strobe function that can be used as a signaling tool or can be used to disorient or distract a target. All modes can be accessed and shuffled through using the simple side switch, which has a built-in memory function to remember the last output setting you were using.

Rugged Design

Despite delivering such impressive power, the S2 Baton is extremely compact, measuring just over 4 inches in length and less than an inch in diameter. The pint-sized illuminator is able to run on either a single 18650 battery or a pair of CR123A batteries. The S2, with its body crafted from hard-anodized aluminum and its lens made from tempered glass, is impact resistant from up to 1.5 meters and is waterproof and submersible up to 2 meters underwater without damage. To prevent accidental internal damage, the flashlight also features advanced thermal management safety programming and reverse polarity protection to keep both the flashlight and its batteries safe. The S2 even comes standard with a strong magnetic tailcap which can be used to attach the light to a number of metal surfaces for hands-free operation.

Olight once again makes a great flashlight
November 29, 2016
Olight products are relatively new but a welcomed addition to my flashlight collection. In a nutshell, the S2 is very bright, well balanced, has a very useful range of light outputs, super compact (for an 18650 light), and just all around useful. IMO, build quality is great and the design is well thought out. For me, I feel that the S2 beam pattern is the best for a general carry pocket light. The TIR provides a very large circle of evenly well distributed useful light for day to day use. I like that the TIR output does not blind you when using the light up close for detail work. It also provides what a describe as a great projection of flood light when illuminating something off in the distance. I use this light every night when walking my dog and it's perfect. The light is very compact for an 18650 and feels very comfortable in the hand. The magnet in the tail is a very nice touch that I wish some of my other lights had. Its super useful for me when I need to go into my shed and I don't have enough hands. I'm giving it 4 stars instead of 5 because the thin string on the lanyard that attaches to the tail cap frayed and snapped within a week of me having the light. It might be that the edges in the eyelet on the tail cap might be a little sharp? I've had to tie a knot in the lanyard string to salvage the lanyard.
  • All around useful light. Very compact for an 18650 light. TIR beam pattern is perfect for general purpose and close up work.
  • Lanyard attachment loop snapped within a week of use. Might be due to sharp edges in the machining of the eyelet in the light's tail cap.

I'll try to keep this concise. This light is has excellent beam properties, a good interface, and for the power source it has a tiny form factor.

That was my main concern when I found this light. Compared to other 18650 lights, it's a good inch or more shorter. Also I'm getting more use than I thought I would out of the magnetic tail cap.

Having a shallow reflector gives it a relatively broad bright spot with excellent spill. It's not a throw monster, but it has plenty of power.

The interface is one button. Press to turn on and return to your previous normal(4 levels) light level. To change between those, hold the button down for two seconds. From OFF, press and hold for a moonlight mode. That is about the brightness of my phone, but more focused. Press the button several times in rapid succession and that gives you strobe. I don't have the manual any longer, but there are two turbo modes which I've never really needed. Double click to activate and then double click again for a longer running version. The light will flash twice to indicate it's in that mode.

It really only has one "flaw" and that is the side button is not very obvious. That is actually a plus for keeping it in my pocket, but I've considered putting some kind of textured sticker on the button. It's really not that bad, I've just been spoiled by tail switches.

One bonus feature is that it includes a plastic sleeve for using 2 CR123 batteries and keeping them from rattling around. I have two of these lights and one of them I use like this for longer shelf life.
  • Small form factor
  • Very bright
  • Good beam properties
  • Simple interface
  • Magnetic tail cap
  • Side button can be hard to find in the dark

Small size... lots of power... comfortable to hold in the hand
March 19, 2019
I was looking at some reviews on YouTube and noting once again how popular the Olight S1 Baton is, but I have an older flashlight filling that role I just didn't feel the need for another small light. But then, I ran across some reviews on the S2 Baton using the 18650 battery. Suddenly, I realized, I have four under- utilized 18650's for only one light that uses them. Aha! A great excuse to purchase a new more up-to-date flashlight. And, it has worked out great! The S2 has lots of power in a form not much larger than the S1, a side switch I've been wanting, and access to the several power levels makes sense to me. A very good purchase!

Very bright light for its size. With the 18650 bat. it lasts longer than any other light I have that is its size.
  • Size, magnetic tail cap and its bright for its size.

Small package, big punch.

So far this little titan has impressed. Great lumen output in such a small frame, with the option of two CR2's or one 18650 for power needs. Going thru the different modes is effortless and everything feels like they're using quality parts. With that said I'll continue to put it through it's paces but this one is a keeper so far.
  • Quality parts
  • Good lumen output
  • easily accessible
  • none so far
