Olight S2R Baton II Lime Green Flashlight Review

Olight S2R Baton II Lime Green Flashlight Review

The Olight S2R Baton II flashlight has been around for a good while, but now it’s available in a neutral white temperature! Read on!


Official Specs and Features

Here’s a link to the Olight S2R Baton II flashlight product page via ShareASale.

Versions

Whew, are there versions!  If we’re just talking about this light specifically, there are at least 12:

Olight S2R Baton II flashlight versions

There’s also an S1R, which is a 16340 cell version of the same light. It’s also available in many colorways.

This Lime Green version is special in some sense, though, because it’s the only (or one of the few) that offers a Neutral White tint. (Some of those “Spirits” might have had non-cool-white emitters, but I can’t recall.)

Price

The Lime Green version of the Olight S2R Baton II flashlight sells for $74.95 right now. As with many of these editions, it’s likely a limited edition. Keep that in mind when ordering! Here’s my ShareASale link for the Olight S2R Baton II flashlight.


Short Review

With all the Warrior Mini and Warrior Mini 2’s that have come around lately, I’d honestly forgotten about the S2R Baton II.  I love the Baton series, though (I have many, many of the 16340 cell version), so when this one hit my hands I remembered instantly how much I like the format. I am pleased that Olight is offering a neutral white CCT! This specific emitter is more green than I prefer, though. You can see more about that below. As for using and output of the light – I love it!

Build Quality and Disassembly

Olight S2R Baton II flashlight

You might remember that I’ve reviewed an S2R Baton II before, years ago. That was a combo review with the S1R II Baton (yes, the naming scheme/order is different between the two!).  Here’s that review of the Olight S2R Baton II and Olight S1R II Baton flashlights.

I don’t think much if anything on the body of this light has changed. Really the only update is the emitter, as far as I can tell.

The threads are square-cut and adequately lubed.  One thing, in particular, I like about the knurling is that it makes unscrewing the body very easy.  There is no [removable] tailcap; to remove the cell, one must hold the head and unscrew the body.

There’s a spring on the head and tail.  The tail spring(s?) are for electrical contact and aren’t in any way for impact resistance.  The spring on the head is quite stiff, though, so it should provide a reasonable amount of impact resistance.

Size and Comps

S2R Baton II Officially:

Weight (g / oz) 98.5 / 3.47
Length (mm / in) 100 / 3.94
Head Diameter (mm / in) 23 / 0.91
Body Diameter (mm / in) 23 / 0.91

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Retention and Carry

This light includes a pocket clip. The pocket clip has a specific place and orientation – just opposite the switch.  This is a two-way clip, so technically could be carried bezel up or down, but the only reasonable way is really bezel up.  Though the pocket clip is opposite the switch, I didn’t have any problems with accidental activation, and I didn’t tend to lock the light out.

The clip is a friction-fit clip, but does have a lanyard attachment hole on the top shoulder.

During testing, I ran the Olight S2R Baton II flashlight without the pocket clip and I have to tell you, it sure is sleek this way.

Above, you can see the lanyard attachment hole in the tail end. Below, you can see the lanyard attached. Olight includes a little “needle” to help install the lanyard. That really helps, and might even be “necessary.”  I appreciate it, anyway.

There’s a magnet in the tail end, too. That magnet is mainly for charge connection, but is actually plenty strong for holding the light, too.

Power and Runtime

The Olight S2R Baton II flashlight includes a proprietary 18650. There are both positive and negative contacts on the positive end, (and only negative on the negative end). This facilitates on-board charging. These lights will not charge any type of cells except these specific Olight cells. Note though, that the S2R Baton II will work with non-proprietary (button top) cells!! However, charging is not possible on standard 18650 button top cells.

The cell fits in an unusual way (but not all that unusual for Olights). This is required because of the charge circuit. Normally, the positive terminal goes toward the head. In both of these Olights, the negative terminal goes on the head end.

Here are a few runtimes. Unlike the old models (specifically the S1R II Baton), this version doesn’t seem to shut off at a low voltage – these tests ran into the 2.58V range. By that point, the switch had already been indicating low voltage for some time, though. So mind the switch!

I don’t see the switch indicating information in the manual, but I note that the switch indicates as follows:

Green: Cell voltage acceptable
Red: Cell voltage low
Red flashing: Cell voltage very low (stop using)

Charging

Like many other Olights, the Olight S2R Baton II flashlight uses Olight’s very common proprietary magnetic charging connector. The charge base on this light is just charge base, and doesn’t double as a two-stage switch as we see on a light like the Warrior Mini 2.

The charging base is the common Olight MCC, which can charge at 1A, 1.5A, or 2A.  As I said above, this cell can be charged in a regular bay charger too!

Charging proceeds at well over 1A, and the 3200mAh cell is charged in around 4 hours.  The charging base is red when charging, and green when not being used or the cell is “completely charged.”  I noted in charge testing that the indicator on the charger would turn green before the trickle CV phase had stopped putting power into the cell.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 1150-400 2m-230m 1320 3.01
High 400 4h 473 0.75
Medium 120 14h 142 0.21
Low 15 100h 18.5 0.02
Moon 0.5 60d 0.6 0.00

Pulse Width Modulation

Nothing really to mention here.  None of the modes seem to be using PWM.  That wave graph on the second to lowest mode is fun, though.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

The Olight S2R Baton II flashlight has an e-switch on the head end of the side of the body.  The switch cover has a bit of texture and is proud enough that it’s easy to find.  It’s also not so proud or soft that it will easily activate accidentally.

It’s an indicating switch, as I said above, too.  It can indicate in green (seen below) and red. (And maybe orange, sometimes it’s faint enough to be hard to say for certain.)

The UI is unchanged from the “historical version” of this light.  Here’s a UI table!

State Action Result
Off Click On (mode memory)^
On Hold (release at desired mode) Mode cycle (Moon, L, M, H) (no Turbo)
Off Hold Moonlight
Any Double click Turbo
Any Triple click Strobe
Strobe Click Off
Strobe Hold Previous Mode
Off Long hold (past Moonlight) Lockout
Lockout Hold Unlock to Moonlight
     On Click and Hold (quickly)^^ Timer (Single blink: 3 minutes, Double blink: 9 minutes)
 Timer Click and Hold (quickly)^^ Switch between 3- and 9-minute timers.

^ Moon, Low, Medium, and High are memorized.  Turbo is memorized as High.
^^ The manual states this as “Double click and hold” but I think “Click and hold” quickly.  Any form of double click ends in Turbo or Strobe.

LED and Beam

In this version of the S2R Baton II is a Luminus SST-40-W emitter. That emitter is coupled with a TIR and provides a very pleasant beam profile.

Olight is using a neutral white (rated 4000K-5000K) SST-40, and the tint of this emitter matches the body and switch indication seen below quite well.

It’s hard to see it here but below you’ll be able to tell why I like this beam profile so much. It’s very even across the center and useful range but does have some spill. I love these even-type beams!

LED Color Report (CRI and CCT)

Here’s really the main issue with this emitter. It’s green. On the low modes, it’s not just a little green. It’s very green. In the highest couple of levels, it’s more or less ok, but the positive Duv on the lower modes is not something I look for in an emitter.

It’s noteworthy though, that the CCT is right within the range that Olight claims – between 4000K and 5000K.  Nicely between, actually – 4400K to 4800K by my measurements! The CRI that Olight claims on the bezel is 70, but by these tests that number seems a bit optimistic – I’m seeing between 64 and 65 CRI. That’s quite low!

Beamshots

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Conclusion

What I like

  • Build quality is quite good
  • Complete package includes charging and cell
  • Works with non-proprietary cells (but can’t charge them)
  • The UI retains neat features from previous models, like the 3 or 9-minute timer
  • Knurling makes for great in-hand feel and usage
  • Great neutral white CCT!
  • Timer feature is neat

What I don’t like

  • Proprietary cells
  • Very green tint
  • Very low CRI
