ZeroAir Reviews: Olight S2A Baton

Preface

I still have a few Olights to review, and the next is the Olight S2A. This was sent to me by Olight, through Going Gear. I happen to like using AA’s in lights because I have a ton of Eneloops around the house, so this is a nice model for me. This will be very similar to the S2R and S1R I recently reviewed, but there were enough differences I wanted to review them separately. Special thanks to Going Gear for sending these my way!

Short Review:

Another in the Baton series, with little surprise. The S2A works well, and handles very nicely. It’s a great choice if you’re married to using AA cells.

Long Review:

Pictures

Here’s a good ol’ regular album, and some beamshots using two Eneloops. My runtime also uses Eneloop AAs.

Package and Manual

This is a typical Olight package, but it’s a step down from the S1R/S2R packaging. It’s very complete but (fortunately, imo) does away with the huge sheet of manual, and the holding–my-hand-through-package-opening notes. I like that. I know how to open a box, so I don’t need all the other stuff from those newer packages. That said, everything you need is included in the package.

The manual is more succinct and smaller than the new manuals – that’s because there are many fewer languages included. As our primary audience here speaks English, I’ll unapologetically call that a good thing.

Build Quality, Disassembly, and Durability

I’ve said it before about the Olight Batons: There are no surprises here. It’s a high quality light, with everything working like it’s supposed to. If you’ve handled any other of the current generation Baton series (and even some of the recently replaced models, this will feel the same. My one concern when I saw this released was that silicone colored handle. I was afraid it’d have edges begging to peel. I can safely say now that those edges are nicely flush with the body of the light and I don’t expect they’ll peel or roll or anything. Also, I truly like that grippy bit more than I expected, and wouldn’t mind seeing that in some smaller models. Particularly because it’s GITD. 🙂

Look at those big ol’ square cut, well lubed, anodized threads!

And the tailcap has a nice, thick spring. The head also has a small but thick spring, keeping those cells nice and snug.

I tend to keep the spare o-ring on the head of the light. I’m not sure this is the best place, but I can say I know where it is (unlike many other spare o-rings I have.)

18 - 1HFcJTy.jpg

One minor thing I like on the SxA series is that the tailcap is slightly longer (than the SxR), making it much easier to screw on.

These Batons aren’t to be disassembled. They can be but so can Macbook Airs. You feel me?

Size

Quoted size is 132mm in length, and 23mm in diameter. Note how long and slender this light is. It feels ok in the pocket but it’s just a touch long in my opinion. However it’s thin enough that it still carries well.

Here you can see the S2A compared to other similar lights.

Retention

There’s a clip and a lanyard. This Baton has no magnet. I doubt it’d work anyway. The lanyard includes a little pin to help with installation, and it connects on the tailcap. The pocket clip can only connect on the head side, right under the activation switch. The clip is a deep carry, putting the head of the light right at the edge of a pocket.

Power

The S2A Baton requires two cells, AA sized. It ships with 2 Olight brand AA lithium primary cells. I have used exclusively Eneloop AA’s for shots and tests etc, and that’s what I recommend (but you do you). The manual only mentions accepting Lithium and Alkaline. These cells are of course, in series, which puts the working voltage in the ~3V range. I would not recommend using 14500 cells in this light, as I don’t imagine the driver can handle the ~7V they’d supply (and isn’t reported to be able to in the manual).

User Interface and Operation

Very standard Baton series UI on this S2A. There’s just the one silicone side switch. It’s kind of small and the bezel makes the reveal of the button kind of low, but it’s a nice clicky. I’ll admit, I often have trouble finding these buttons without actually putting my eyeballs on them. And in that vein, it’d be nice if they were something that wasn’t black. (GITD, anyone??)

*** Double click to switch between 3m and 9m timer. Light will flash 1x for 3m and 2x for 9m.

LED and Beam

The emitter is a Cree XM-L2, and it’s behind a TIR optic. The tint, is green to my eye. The beam shape is fantastic for the Baton size – a ‘flat spot’ with little roll off. I really like TIR beam profiles.

Beamshots, Runtime, and Lux Measurements

The runtime was performed with two Eneloop cells. Light stopped being produced when the cells were at ~1.13V (individually).

Random Comparisons and Competitive Options….

I’m surprised to say that there are quite a few competitive options in this AA, XM-L2 category. None of those options seem truly exceptional, and they’re all in the same price range as this Baton. So my edge goes to the S2A because I do actually like the GITD silicone handle.

Conclusion

What I like

  • Uses AA cells
  • GITD handle
  • Olight quality
  • Works pretty well in the pocket
  • TIR

What I don’t like

  • It’s kind of long but… it uses 2xAA – so it is what it is
  • 550 lumen Turbo seems a bit low for the Baton series

Final Thoughts

This is more or less an iterative Olight Baton. If you’re married to AA cells, then this is a great option. Most of the Batons are great, though, so give them all a look and a test to see which one is right for you.


Parting Shot

Can’t tell if the S2A is jumping in this pic or not. Maybe.
