How to operate

ON/OFF: To turn on the light, single-click the side switch, the flashlight outputs at memorized brightness level, single-click again will turn the light off.

CHANGE BRIGHTNESS LEVEL: Press and hold the side switch when the light is on. The output will cycle through low - medium - high - turbo mode. Release the side switch when the desired brightness level is achieved.

MOONLIGHT: From off state, press then hold the side switch for 1 second enables the moonlight mode.

DIRECT ACCESS TO TURBO: From off state, double clicks directly activate turbo mode.

STROBE: Triple-click the side switch to activate strobe mode, any other operation will quit the strobe.

TIMER: The light contains two timer settings: long timer (9 minutes) and short timer (3 minutes). Double click the side switch to enter this setting. Output blinks once means 3 minutes short timer, blinks twice means 9 minutes long timer. Double click the side switch to change the timer to the opposite setting. The light will automatically shut off when the timer is overflow.


- One of the five following output modes: moonlight, low, medium, high and turbo, will be memorized after the light turns off. (The flashlight will only memorize high and turbo mode fo 10 minutes after the light is turned off, the memory turns to medium mode)
- Moonlight mode is not among of normal dimming sequence (low - medium - high - turbo), from moonlight mode, press then hold the side switch to enter into normal dimming sequence.
- In the beginning of turbo mode, the output will be in maximum for 3 minutes, within following 1 minute, ouput ramps down to 60% of the initical output.
- When the strobe mode on, press and hold the side switch and te light will quit strobe mode, and it will then return to the memorized mode.
- Except the black one, all other colored ones are fluorescent

My impressions:


+ High build quality, not seen any scratch (checked all four lights) etc. well lubricated thread/o-ring (not too much, but ok)
+ Dust free lens, I've not seen any problem inside the lens, checked all four S2A. (same experience as earlier baton models)
+ Very nice, quality beam, has huge hotspot, no rings etc, I really like TIR solution, good balanced beam. Very useable in many situations
+ Nice white tint with slightly yellowish color, so it's not a horrible bluish, purplish "cool white" tint
+ NO PWM OR OTHER IRRITATING things, all mode (except moonlight, pls check other comments) looks perfect, absolutely flickering-free.
+ User friendly UI, simple to use, direct access to turbo or moonlight mode, hidden strobe.
+ Good performance from two AA batteries (max 550lm)
+ Really long runtimes, especially with lithium batteries (50 days in moonlight mode or more than 3 days in low mode, 20lm)
+ Well spaced modes, direct access to turbo and moonlight mode
+ The fluorescent silicone surface on the body a very good feature, you can find your flashlight in the night easily
+ Timer function also looks very useful, I really like it
+ Removable clip
+ Came with 2pcs lithium batteries, date code 2016.05 (expire 2026.05)
+ 5 years warranty


- there is no holster
- there is no lockout function

Other comments

- Strange, but I've seen pwm(?) effect in lowest mode (moonlight), but it's an extremely fast, so absolutely not visible in real life use.
- I would like to see 14500 li-ion support
- I would like to see neutral white version, not only cool white

If you need a really good quality, versatile AA flashlight around the house or in the car etc. I highly recommend S2A.

R50 Seeker (1*26650, XH-P50 LED, 2500lm)

Earlier model, R40 was a good versatile flashlight, but now R50 looks better for me. Ok, Olight still use same, "only" 4500mAh cell, but performance much better, much more lumen than R40. Thanks to Cree XH-P50 LED. Now max output is 2500 lumens (R40 was max 1200lm). Impressive performance from a relative small flashlight. Check the R50 vs R40 beamshot comparison pic!

+ Low voltage indicator (activated when battery voltage was 3.42V)
+ Lockout function
+ Charger stopped at 4.18V, perfect!
+ Can stand in candle mode
+ 5 years warranty


- Can't charge other batteries in the flashlight (but you can use other 26650 cells)
- there is no holster
- there is no moonlight mode

Other comments

- It's a new light with one of the newest high performance led, so I don't understand Olight, why can't use a higher capacity battery as 4500mAh? 5000-5200mAh cells available on market.
- I would like to see neutral white version not only cool white
- R50 PRO is coming soon with XH-P70 LED and more than 3000 lumens output
- Slightly yellowish tint (for me it's better than ugly purplish, bluish "cool white" tint)
- USB adapter surface looks extremely sensitive, can be easily scratched, be careful. Otherwise USB adapter output is 2.1A.
- Battery original voltage was 3.78V. Charging time 3.78V to 4.18V was ca 3h 15 mins

Olight S1R (XM-L2, 1*RCR123/16340, 900lm)

I really like the original S1, because it's really tiny and powerful light, perfect to every day use, so I'm curious how working the new S1R.

Official specs, features

The S1R baton (S1R) is a side-switch, rechargeable EDC flashlight, powered by one RCR123 rechargeable lithium battery of high discharging rate, giving a maximum output of 900 lumens. It ulitizes Cree XM-L2 LED. Coupled with TIR optic lens of high light transmission rate, it can deliver a balanced beam. S1R has five brightness levels and a strobe mode, covering an output range of 0.5 to 900 lumens. The outer appearance of S1R follows the style of BATON Series. It comes with a magnetic charging cable. You may use a desktop micro-dok as an optional charger, which makes it easier to acquire the power source whether at home or outdoors, and make sure the flashlight is always ready to bring brightness to your life at any time.

- Cree XM-L2 LED
- Powered by a 550mAh RCR123 customized battery of five times discharging rate, giving a maximum output up to 900 lumens
- The flashlight can be charged through the magnetic contact charging port (other batteries may also be used in S1R, but cannot be charged)
- New 750mA portable USB charging cable
- Brightness increases or decreases gradually: when the flashlight is switched on/off, it will light up or fade gradually to protect eyes from the stimulation caused by sudden brightness changes
- Flat magnetic tailcap that allows it to be secured to ferrous metal surfaces as a hands-free option
- Lockout mode can be activated on the side switch for accidental triggering protection, along with a low-voltage indicator underneath
- Reverse polarity protection circuits
- Timer Setting: Short (3 minutes) and long (9 minutes)
- The standby current is below 30uA

- Output: 0,5lm (15d), 12m (33h), 60lm (4h30m), 300lm (1h), 900lm (30 sec continously, but total runtime, not more than ca. 3-4 mins)
- Peak Beam Intensity: 5250cd max. distance 145m
- Length 66mm, diameter: 21mm


- Lanyard
- Pouch
- User Manual
- Micro dok (optional)
- MCC Magnetic Charging Cable + 550mAh 5C RCR123A Battery


ON/OFF: Single click the side switch to turn the light on/off. When the light is turned on, it will return to the previous brightness level selected before the light was turned off. When the flashlight is switched off, the current mode will be memorized. Modes that can be memorized are: Moonlight, low, medium, high and turbo (High and turbo mode are memorized for only 10 minutes. After that, the memorized mode will revert to the medium setting).

CHANGE BRIGHTNESS LEVEL: When the flashlight is on, press and hold the side switch to automatically cycle through the low, medium, high, and turbo modes. The mode is selected when the side switch has been released.

MOONLIGHT MODE: When the flashlight is off, press and hold the side switch for over one second to access the moonlight mode. If the memorized mode is moonlight, simple click the switch to access it.

DIRECT ACCESS TO TURBO MODE: When the flashlight is off, quickly double press the side switch to activate the turbo mode; when the flashlight is on, quickly double press and then hold the side switch to activate the turbo mode.

STROBE: Quickly triple click the side switch to enter the strobe mode. To quit this mode, single click or press and hold the side switch.

LOCKOUT/UNLOCK: When the flashlight is off, press and hold the side switch (for about 2 seconds) to access the button lockout mode (the flashlight will enter the moonlight mode first and will then switch off to signal the lockout mode). Under the lockout mode, press and hold the switch for less than one second without releasing it. The red indicator below the switch will be on for a short time to signal that the light is still in a lockout mode. To unlock it, keep holding switch for over one second until the moonlight mode is on again.

My Impressions


+ Excellent quality, clear, dust free TIR lens, well lubricated o-rings, thread (not much, but enough for smooth operating)
+ Same, excellent beam quality as S1 without any rings or others. Very large spot, thanks to TIR lens
+ Low voltage indicator
+ Timer function
+ Removable clip
+ Lockout function (S1 came without this function)
+ Magnetic tailcap (removable) one of the best and useful feature
+ There is no PWM or other irritating flickering (except moonlight mode, pls check other comments)
+ Very small sized charging system (for me it's better than the charging dock) with fast charge current (750mA)
+ 5 years warranty


- Own S1R charger stopped at 4.23V, for me it's too much, 4.18-4.19V would be better
- Can't charge other batteries in this flashlight

Other comments

- I've seen same pwm(?) effect as S2A in moonlight mode. Not visible in real ife situations, because flickering looks extremely fast, but strange because original S1 (or S2) was perfect in moonlight mode. Of course other modes looks OK!
- 900 lumen sounds very good, but don't forget, you can use this mode very limited time, check my runtime test. Total runtime not much more than 3-4 minutes! Continously 30 sec.
- There is no holster, but you get a very nice and really good quality little pouch/bag
- I would like to see neutral white version
- You can use other IMR cells in S1R
- If you want you can charge Olight IMR cell in other chargers (eg XTAR VP series) but be careful, because it's a customized battery.
- 750mA charge current is fast enough and not problem for RCR123/16340 sized IMR cells
- Olight IMR battery (ORB-163C05, 550mA) size:
diameter: 16,7mm
length: 34,3mm
(I've used a Mitutoyo digital caliper)
- Battery original voltage was 3.82V

Ok guys, here are some photos, sorry still not too much, but more pics (incl beamshot) coming in this week or next week.

As you can see S1/S1R has much larger hotspot than S10R II.

I have R20 Javelot, SR52 (XM-L2), S2, S20R, SR Mini II too, so if you need side by side beamshot comparison pls tell me and I will try to share
