Olight S1A review (TIR,600lm,XM-L2,AA)


This review will be dedicated to the latest member of the Baton family, the S1A.

What’s new with this light?

1. TIR optics.
2. New button, new bezel color (compared to old single AA battery powered Batons …).
3. A record (for Olight’s powered by a single 14500) 600 lumen.
4. The flashlight got much shorter, was added two timer modes.

The flashlight is very similar to the S1, only it is a little longer and can also work from other than Li-Ion battery types.


LED: CREE XM-L2 LED Power Source: 1 x AA (Lithium or Alkaline) OR 1 × 14500 IPX Rating: IPX-8 (Waterproof and submersible up to 2 meters) Impact Resistance: 1.5 meters Brightness Outputs (Using 1 × 14500): Turbo (14500 Only) – 600 Lumens → 300 Lumens – 1 Minute → 1 Hour High – 220 Lumens → 100 Lumens – 1 Hour 40 Min. → 10 Minutes Medium – 50 Lumens – 6 Hours 30 Min. Low – 5 Lumens – 60 Hours Ultralow – 0.5 Lumens – 15 Days Brightness Outputs (Using 1 x Lithium Primary AA): High – 220 Lumens → 100 Lumens – 1 Hour 50 Min. → 30 Minutes Medium – 50 Lumens – 10 Hours 30 Min. Low – 5 Lumens – 80 Hours Ultralow – 0.5 Lumens – 25 Days Peak Beam Distance: 118 Meters (Using 1 × 14500) Peak Beam Intensity: 3480 cd (Using 1 × 14500) Dimensions: Length – 3.13” (79.5 mm) Bezel Diameter – 0.83” (21 mm) Body Diameter – 0.73” (18.4 mm) Weight: 1.29 oz. (37.5 g) (Excluding Battery)

As we can see, for the maximum brightness setting a 14500 cell is required. There is still a strong removable magnet at the tailcap.

Shall we begin?

The flashlight comes in a little plastic semi-transparent box. The box has the technical specs of the light, and you can see the light as well.

The flashlight comes bundled with a quality lanyard, user manual and a lithium battery (non-rechargeable).

Here is the light. It is really tiny. There are no quality issues – it seems to be very well made. The button is not too stiff and not too soft, there is no electronic lock-down of the button.

A bit about controlling the light

The strobe mode is being activated with triple click from any mode, I really like it.

The tailcap has gold-plated spring, and the removable magnet beneath it. The positive lead of the flashlight can be seen in the picture – it is not a spring.

Comparison with the closest Baton “family member” – the S1. As you can see the flashlights are very similar – not only physically, but also in controls and the light distribution.

A comparison with other AA powered flashlights. As you can see it is even more compact than the Zebralight.

And a comparison with a bit outdated S15 Ti. The TIR optics really reduced the length of the light.

Some numbers (lux at a meter distance)

The flashlight has a huge hotspot and not much spill -just like the S1. The light is pure white – no green or blue tints were detected. No PWM or noises were emitted by the light.

Let’s see it in action?

TIR optics, coupled with a high powered LED equals a great close range illumination.

Video Review

Conclusion, final thoughts

Evolution in progress. A really great light just got better – brighter, more compact with even more practical light. Easy to control, looking good – as close to perfection as ever.

I would like to thank Olight for providing me the review sample
Questions? Suggestions? Let me know and I will be happy to assist.

Good review, thanks!

Any chance of doing a runtime chart on nimh?

I’d love to get one of these, but I’m not seeing where it says it supports 14500’s though. BTW, I do have an S1. It’s a great flashlight. Tiny, and super bright.

We may get a lot of parallel reviews of this, since Olight emailed some BLF members the offer of a free flashlight.
I got one of them.

I put my first take comment in another of the review threads at BLF that was started yesterday:


my comments are at

See also another review thread at:


And you’ll also see reviews popping up at other flashlight sites.

Yes, li-ion is supported — I’ll have to find the package insert

EDIT, it’s pictured above in the original post
http://i12.photobucket.com/albums/a235/viperxp1/Flashlight%20Reviews/Oli... to quote from it, its “Turbo” level comes up when a li-ion is used.

My only negative observation so far is that the 5 year warranty is only supported if you mail your problem light back to China.
They should fix that and let local dealers or a local repair address be used for any warranty problems.

Thanks for the review.

I’d like to see Olight offer this with a neutral emitter.

I am glad that you liked it.
Sorry, currently runtime charts are beyond my capabilities.

Past experience shows that it will happen, but only with some limited editions. Hope not to be right.

I’d like to see some comparison with your S15, which I imagine performs much better at any distance above like 10ft.
