Review: Olight S1 Baton

Olight S1 Baton

*Flashlight provided for review courtesy of

The new Olight S1 Baton is an update to the S10 Baton, one of the favorite flashlights for many flashaholics. The S10 has that fantastic Olight UI along with great output and that tiny size that disappears in our pockets until it's needed. I'm sure many expected any updates to this great little light to be nothing more than an slight UI change along with maybe a different emitter and/or switch. If that's what you expected then you'll be disappointed. They made it even better than before.

Olight made the S1 Baton the their smallest side-switched light and easily one of the smallest on the market. This thing is TINY. I purchased my S10 baton and S20 Baton lights a couple years ago but I never really care much for the S10. It was too short and the battery life was limited compared to the more comfortable and longer lighting S20 Baton (18650). Here is the odd thing though...even though the S1 is even smaller than the S10 in every way, it just feels better in every way too. Suddenly being even smaller than the original S10 makes it the right size now...somehow. Hard to explain but if you thought the S10 was too small you might actually really like this S1. If you really liked the S10 you will LOVE the S1!

Let's take a look at Olight's specifications to get an idea what the S1 is capable of...

All OTF (Out The Front) lumen measurements were taken on my Integration Sphere which has been calibrated against many proven ANSI tested flashlights and other lights with known output levels. Testing done at ANSI standard of 30 seconds of on time. All Lux and Throw measurements are taken at either 3m or 9m distance then converted back to 1m distance for greater accuracy. Both Lux and throw measured at 30 seconds. Throw distance is measured to distance at which light level is 0.25 lumens.

Cell(s) used: AWT IMR 16340 and TF CR123A
Testing voltage of cell(s): 4.19V and 2.94V

It's uncommon when my tests read higher than a manufacturer's ratings but this light is one of them. It really is a little giant! I did notice something different with the beam due to the unusual TIR optics and explain that in the notes just below.

16340/RCR123A (4.19V)

  • Thermal sag isn't anywhere near what I expected using a 16340 cell as it only dropped 19 lumens in the first 30 seconds.
  • Throw was substantially higher as well but for a particular reason. If I measured in the dead center of the hotspot (from 3m distance) my readings were about where Olight says they should be but if I moved my meter out towards the edges of the hot spot my readings increased substantially. Peak Lux is what we are looking for here so that is what I will stick with. 5091cd and 142.7 meters of throw.

CR123A (2.94V)

  • My OTF readings were nearly identical with the higher voltage cell in the first three modes where the boost circuit isn't working hard. Max OTF output was roughly 120 lumens less but only 14 lumens less than what Olight claims for what I am guessing is the 16340 cell.
  • You could see the boost circuit really working as it ramped up output after the initial turn on where it gained about 40 lumens before leveling off instead of losing lumens like most lights do.

^ The Moon low on the S1 (right) seems far less bright than the original S10 (left).

^ On the highest output the first thing I noticed is the different shape of the beam thanks to the new TIR optics. Spill is FAR less wide than the S10 and most of the light is concentrated into the fat center hotspot for a much more useful beam for an EDC pocket lamp.

Because of the high output and tiny thermal mass available, there is a 1 minute timer in the highest mode where it will automatically cut output from 100% to 50% to protect the driver, emitter, and cell from overheating.

The other thing you might notice is the lack of crappy green tint in the new S1. Ignore any purple tint you see an any of the beam shots I've taken. The backdrop above is black poster board which is why it looks purplish.

User Interface (UI)

  • With light Off
    • Single-click the side switch to turn On the light.
      • Output level will return to the last output mode (except strobe mode).
    • Instant Access to Moon Low:
      • Press and hold the side switch for 1 second to activate Moon low
    • Instant access to Highest output:
      • Quickly double click the side switch to activate Highest output
  • With light On
    • Changing brightness levels:
      • Press & hold switch to cycle through Low, Medium, and High brightness levels.
      • Release switch at desired brightness level.
    • Quick access to Strobe:
      • Triple-click the side switch to activate strobe mode.
      • Single-click to quit strobe and return to previous output level.
    • Turn light Off with a single-click.
  • Special Timer modes:The S1 contains two timer modes in which the light will turn itself off after being on for 3 or 9 minutes. Both timed modes can only be accessed with the light already turned On.
    • 3 Minute Timer:
      • Double-click the switch to enter the 3 minute timed mode.
      • The light will blink once (long blink) then remain lit for 3 minutes or until turned off manually.
    • 9 Minute Timer:
      • A second double-click will switch to the 9 minute timer.
      • The light will blink twice (one long then short) then remain lit for 9 minutes or until turned off manually
    • Either of the timed modes will run in whichever output level you were in when entering timed mode.

I didn't think much of the timed mode until thinking about when it would be useful. Remembering the last time I went camping I realized how great it would be to have the S1 and set the timer with the light hung from the ceiling of the tent. This would allow you to settle into your sleeping bag without ever having to get out to turn off the light. Pretty nice and useful touch for them to add to the S1. :)


^ The S1 come packaged in what has become Olight's usual clear plastic boxes. I like it because you can see exactly what is in it.

^ The rear of the box shows some details and specifications.

^ In a new twist, the spare O-rings are used to hold the S1 in place in the box. Be sure to be careful when unattaching the light fro the cardboard and be sure to not throw away the O-rings accidentally. ;)

^ Inside the lower part of the main box is a smaller box that holds the thick, attractive lanyard. As far as factory lanyards go this is a really nice one. I still never use them because I don't trust the super thin attachment cord that goes through the tiny lanyard hole in the tail cap.

^ The instruction manual comes in both English and Chinese. It's pretty straight forward and easy to understand unless you don't read Chinese...which I don't. But I do read English quite well (better than I often write it) and the English instructions are pretty straight forward and simple as well.

Detailed and Up-Close View:

Let's have a closer peek at the S1 itself. This is my favorite part because a good photo says more about quality than words ever could. My photos might not be the best so I will chime in with words now and then. As always, clicking a pic opens the full resolution version in a new window/tab.

^ Aside from the diminutive size of the S1 there are a couple f other new features that are noticed immediately. The first, for me anyway, was the blue anodized bezel and switch boot retaining ring. The anodizing on the rest of the light is fantastic right in line with Olight's other offerings.

^ The switch button is silicon and flat and smooth. It's easy to find by feel and large enough for fat thumbs to easily activate.

^ The second thing you might notice is the unusual PMMA TIR optic that replaces the usual reflector and lens used in all the other Baton series lights. It looks like there is a 5mm LED stuck in the middle of a very shallow reflector with no lens over it. Don't worry, it isn't. It is a Cree XM-L2 behind a funky TIR. Without a flat lens over it you will find it collects a ton of dust that you will be wiping out quite often. So far no scratches from it but it's really hard to get the dust out from the crease around the center portion. It doesn't seem to effect the beam which is really quite nice.

^ There are 3 flats machined into the body of the S1. One flat has the Olight logo etched into it.

^ The opposite side has the "S1 BATON" model name and serial number etched into it.

^ The third flat (between the opposite flats) has the battery insertion direction etched into it. Pay CLOSE attention to this little logo! The S1 is unlike 99% of other flashlights in that the battery is installed backwards from what you are used to. The laser guys will find it normal but most flashlight guys will want to install the cell in the wrong direction.

^ As it shows in the instructional logo, the cell is installed with the cathode (negative) end towards the head of the light and the anode (positive) end visible and towards the tail cap.

^ The square threads are prelubricated. The O-ring seals the cap threads well and it has the usual high quality fit and finished expected in Olight's torches. The anodized threads mean you can manually lock out the power current to avoid accidental activation of the light.

^ Check out the excellent knurling that was retained from the older Baton lights. Very grippy and very attractive.

^ A look into the back of the light towards the head reveals a large plastic insulator with the cathode spring poking out for the cell.

^ The tail cap is standard Baton fare. A neodymium magnet sits in the very rear underneath the anode spring. The magnet can be easily removed if you don't like having one in your light.

^ The excellent pocket clip is deep carry and has just the right amount of space to fit over the pocket lip of your jeans. Due to the small size of the S1 and the pocket clip extending almost to the base of the light, clipping it to your pocket isn't as easy as it is with a longer light. Yeah, yeah...first world problems, right?

^ The tail cap has a small lanyard hole to accommodate the included lanyard.

^ Here is the S1 lined up with some other CR123A/16340 lights to show just how small it is. I own only one other 16340 light that is smaller and that would be the DQG Bullet (far right). In order of appearance (left to right) we have: ThruNite Neutron 1C V2, Xtar H2, ThruNite T20T, Olight S10 Baton, Trustfire Mini, Olight S1, and DQG Bullet.

^ The older S10 was an incredibly small light by itself but next to the new S1 Baton it looks like Andre the Giant.

^ Smaller in all dimensions, the S1 is most easily identified by it's blue bezel and funky TIR optic.

^ In the hand it is smaller than you would think. The S10 looks massive next to it.

^ With the magnets in the tail cap, both S10 and S1 show off just how useful they are around the kitchen, the shop, and under the hood of your car.

Beam Profile and Examples

^ The new TIR lens really concentrates most of the light forward with a thick, bright center hot spot and limited but smooth spill.

^ Outdoors the good mode spacing gives two nice close-up modes (Moon & Low), one good midrange mode (Medium) and a great High mode that belies it's tiny size.

^ A white ceiling shot (again, any purple tint is only from the cell phone pic) demonstrates the huge center spot of the S1 (right) against the less bright, smaller, and green tinted spot of the older S10 (left).

^ Here is an animated gif showing the highest output of the S1 against several other lights run by 16340 cell.

Pros and Cons


  • Fantastic build quality
  • Incredibly small but useful size
  • Great output with instant access to Moon and Highest modes
  • Timed shut off option
  • Pretty good throw for such a small light
  • Excellent deep carry clip (removable)
  • Zero visible flicker in any mode
  • Great knurling and grip
  • 3 and 9 minutes timers
  • Hidden Strobe


  • Super small body isn't as easy to clip onto your pocket as it's larger brethren
  • PMMA TIR optic is a dust magnet

Concluding Opinion

Let's face it, Olight is known for making some excellent lights, especially with their Baton series of EDC lights. Great build quality and near perfect UI make them the gold standard and the new S1 takes all that makes the other Baton lights great and makes it even better with it's incredibly small size and greater output. This is an excellent light and at a great price point of around $50 or less on the street/internet. They also have a titanium version coming out too that is simply stunning!

I love this little light and it is definitely "Mac Approved" and recommended.

Thanks for the excellent review Mac.
Having own this pocket rocket myself, glad to read that their OTF lumens are higher than the manufacturer’s specs.

Another great review JM! :slight_smile: i like the fact that this new S1 is the same size as a TF Mini-01 and has a side switch. Also add the new TIR optic eliminates the green-hue of the older S10.

thanks for the review JM!

the S1 crowded the S10R out of my pocket.
at least until the “R“ is coming ;)…

Thanks for the review.

Thanks also JM. These lights are not going to get much smaller than what this is. Its tiny.

nice review. now i cant wait for mine to arrive.

Near perfect EDC light, albeit the LED tint.
Do you think the stainless steel rings are blue because its the cold white version? They must be working on different versions with other color rings.

waiting for mine to show up any day from Banggood can’t wait and again Johnny excellent review .I did have a question as far a the 16340 lion battery I want to get one so I am not burning through some many cr123as, is there a specific brand and rating I should look for to use in this picket rocket?

Nice review JM! I got two already on discount and measured the high lumens as well on a fresh EFEST IMR, older 550 mAh version. Love the UI and performance, but would prefer a neutral tint - little too blue for me, but it's still a great little light.

Of course I want to see if the LED is accessible - no time yet to give it a go...

LJ - EFEST IMR 16340 here:

Always in my pocket since it arrived;
My favourite EDC, no doubt

Thanks for the review JM .

LJ, I don’t ahve any personal experience with them but I would imagine an Olight 16340 would be a natural choice for ok quality. Illumn has them for under $4. I’ve been using AWT IMR 16340 cells and am very happy with the performance and low internal resistance. Tom’s Efest suggestion would be a very safe bet as well and at the same price as the Olight cell I would go with the Efest. RMM is selling them for a great price.

thanks TomE and Johnny Mac,
Ps can’t wait for modded AS31 my son and o are drooling g to see it thanks again.

you do like the AWT batteries Johnny?do you use them for vaping as well?I really like the AWT cells and Vivian os a great lady and knowledgeable on their product line

Nice review, thanks!

For the AS31 mod, might be a little while longer - need to stop development soon and do some full blown testing of the new firmware - gonna take a while, lots of new things. Dunno if the timing is good or bad - bad because of delays, good because of the new features - yours will be the first build having this. Hhmm - it's taken recent group buys like 6-10 months to get this stuff out, hopefully I'll be a lot quicker Wink.

Though this Baton S1 has a darn good UI, my new ATTiny85 based UI should be superior - would be cool to see it in this micro torch...

Thanks for review, JM!
Love to see that Olight delivers even more than what they promise regarding output and throw!
Do you have S15 to compare its throw to S1?

Cant imagine theres even smaller light with even higher output than S15R :D!

Tempted to get one myself now! I mean, that size and output! Now if there was some sort of extension tube available to offer AA/14500 option, that would be great and instant hit!

BG posted the Titanium version as "coming soon":

Looks incredible...

I do not but the AA extension for it Is an awesome idea! Hopefully they will do an AA (S2) and 18650 version. I’d be in for an S3 (18650) in a heartbeat.
