The Olight S2R Baton has been a pretty popular EDC flashlight since 2016, when the first edition came out with a CREE XPL LED and 1020 lumens. 2 years later, in 2018, the 2nd generation was announced, with a Luminus SST40 LED and 1050 lumens. For most EDC use cases, that is likely enough for most of people.

So, what has changed since the 2nd generation was announced in 2018? Nothing on the inside, because the specifications are still the same. But it is a limited edition with a white coating instead of the standard black. And yes, the white anodization looks really white!

Package quality.

Olight takes care of the whole experience, starting from the package. Each and every Olight flashlight I own has a uniquely designed box with accessories. The S2R Baton II doesn’t have as fancy packaging as the Olight Marauder 2 for example but is still adequate for the job. So what’s inside the box:

  • The flashlight: Olight S2R Baton II
  • Magnetic charging cable
  • Lanyard
  • Pouch
  • Extra pocket clip (Blue)

It doesn’t happen too often that manufacturers add an extra colored clip, but Olight added a blue pocket clip, besides the standard black one.

BTW, it’s very difficult to take pictures of a white flashlight on a white background, without blowing out the flashlight itself.

Flashlight in use

The S2R Baton II is a 18650 EDC light, so the dimensions are relatively small compared to 21700 flashlight or even 18650 tactical lights with a rear switch.

Operating the S2R baton 2 is done with a single electronic side switch. There’s no tail switch, in order to reduce the length. And I do agree with the notion that the knurling on the 2nd generation looks much better than on the first generation. Not that this helps too much in terms of quality or handling, but it is definitely a nice ‘upgrade’ from the 2016 model.

The side switch has a little indicator LED that is only visible when the flashlight is activated, so that doesn’t help to locate the flashlight in the dark. The indicator LED also turns red when you try to activate it while in lock-out mode. But since the switch is located on the opposite side of the pocket clip, the switch is easy to locate in the dark.

If you don’t like the black clip on the white flashlight, you can also use the blue reversible clip they included. And since both have the same shape and strength, one doesn’t have any benefit over the other…. except for the color of course.

Tailstanding: since the head looks similar to the Olight Warrior Mini 1, I’m pretty sure you can use its diffuser as well. If not, you can still use any cheap diffuser from the internet and use it as a candle/bedside light.

Build Quality, and Warranty

Yes, Olight also pays attention to its knurling. If you look at the Olight Warrior Mini, or the Olight S1R Baton. you would almost imagine the Olight S2R Baton II to have the same knurling. But no, that’s not the case. I’m not sure which knurling I like better, but the knurling on the S2R Baton II really looks nice.

Threads are coating with the same color anodization as the rest of the flashlight. The first time you open up the flashlight, the threads look pretty white and clean, but after opening and closing the flashlight, the color changes to black due to the lubrication on the threads. Also, I wouldn’t recommend unscrewing the battery tube too often, because the pocket clip keeps touching the body while unscrewing. This could damage the coating unnecessarily.

Oh, and be careful how you insert the battery after charging… the positive terminal goes towards the tail, and not towards the driver!!

LED, Lens, Bezel, and Reflector

Olight doesn’t mention the brand or type of LED, but it seems to be the same as the original S2R II: Luminus SST40. The CCT is supposed to be between 6500K and 7500K. That is pretty cold white. CRI70 is also pretty low, and that’s one thing Olight could improve on: add more choices of emitters.

Olight uses TIR optics to give a smooth and even beam. But you can definitely see the ‘coldness’ of the emitter. The beam profile on the other hand is very smooth with a defined hotspot.

Driver & User Interface:

The user interface of the S2R Baton 2 white edition hasn’t changed from the original baton 2.

  • Not visible by eye

Extra UI info:

It’s interesting to see that when you switch to Turbo from Off, it almost feels like a soft start. It’s not 100% at once, but in a matter of about 1/4 or 1/2 second it ramps quickly to 100%. And when you turn it off, there is also a soft turn off: decreasing the light until it turns off.. Also this happens in about 1/2 second.

Batteries & Charging

Like with (probably) all of their flashlights, Olight includes a battery and magnetic charging cord with the S2R Baton 2. It’s a great magnetic flashlight.

The battery itself is a proprietary rechargeable 18650 lithium-ion battery with 3200mAh. I’m not sure why they didn’t include the same 3500mAh they normally provide with the Warrior Mini and Warrior Mini 2. This battery is coded: Olight ORB-186C32.

Note: to insert the battery, you need to point the negative side towards the driver, and the positive side towards the tail. That’s the opposite direction of 95% of all other flashlights, that have the positive side of the battery towards the front of the flashlight.

Also, the charger cable that was included looks slightly different from the other charging cables I have. The other ones mention: MCC 1A/1.5A/2A, while this charging cable only mentions: MCC 1A. That’s probably to protect the battery from charging too quickly, and reduces the charge current to 1A. On a positive note: you can still charge the battery in a normal charger. But you can’t use a normal battery in the S2R Baton 2. You can also use the MCC 1A/1.5A/2A for charging the S2R Baton 2, in case you didn’t know.


Lumen measurements:

All output numbers are relative for my home-made Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.

All of my readings were taken from an Olight ORB-186C32 battery

ModeSpecs30 secturn on
Turbo11501289 lm1318 lm

Olight was pretty conservative with their numbers and were easily achieved in my test environment.


The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.

First 4 hours

Turbo: starts at around 1318 lumens and at the 2-minute mark, drops from 1250 lumens down to roughly 455 lumens. From that point the output is very stable till it drops to 142 lumens at the 3 hours 51 minutes mark. The next drop is more gradual, from 4 hours and 1minute. Total runtime: 4 hours and 1 minute. The light continues to run for many more hours. When I removed the battery, it measured 2.50V. Not recommended..

High: Stable output from the get-go with roughly 460+ lumens. After 3 hours and 54 minutes, it drops the first time, down to roughly 145 lumens. From 4 hours and 6 minutes, there is the last gradual drop. I stopped the runtime test before the light was shut off. This means that the battery was getting discharged pretty deeply, and I measured again about 2.53V at that point. Total runtime: 4 hours and 6 minutes.

Medium: Very stable output of around 143 lumens for 14 hours. At that point, it starts to drop gradually and continues to run for a couple more hours. After 17 hours I stopped the test and removed the battery. The battery was again at around 2.55V.. Which is pretty low, a bit too low in my opinion. The total runtime is 14 hours.

I didn’t do a runtime test for low and moon, but they are supposed to run for 100 hours (Low) and 6 days (Moon).

Throw Measurement

Measurements were taken both indoors at 5 meters and outdoors at 10 meters with a professional Hagner E4-X Lux Meter.

ModeCandela measuredMetersYards
Moon0 cd00.00
Low100 cd2021.87
Med825 cd5762.82
High2700 cd104113.65
Turbo7675 cd175191.62
Turbo 10m7500 cd173189.42

Moon was impossible to measure at 5 meters. Olight is usually prettey conservative when it comes to output and throw numbers. Turbo is supposed to have an intensity af 4,600 cd, and 135 meters of reach. And as you can see from my measurements, that was easily beaten.


For the following beamshots I used a Canon EOS 5D Mk2 and a 50mm lens. manual settings: ISO1600, 1/4sec , F4, 5000K

The shed is about 65 meters / 71 yards away. 

Disclaimer: This flashlight was sent to me for review at no cost by Olight. I have not been paid to review, nor have I been holding back on problems or defects.

Final Verdict


  1. Small and light weight
  2. Single switch for operation
  3. Special edition with white coating
  4. Comes with battery and charge cord
  5. No PWM


  1. Battery inserts the otherway around, with negative side of battery towards the head

Explanation on star ratings:

1: Avoid: my phone flashlight would be a better choice – 2: Poor: significant defect or issues, much better options available at the same price – 3: Average: some defects or issues – 4: Good: recommended (minor issues) – 5: Great: highly recommended

4.5 stars: ★★★★⋆

The Olight S2R Baton is a small and lightweight EDC flashlight. The only major gripe is the battery. You have to insert it with the positive terminal towards the tail instead of the front. Besides that, the flashlight has great performance and the white coating is something I haven’t seen personally yet.
