Another in a long line of Olight is the Olight M2R.  This one is highly anticipated and regarded, with the momentary and recharging tailcap.  It’s a cool light on paper, so let’s have a closer look.

Official Specs and Features


There are a couple of tint options: NW and CW.  Aside from that, there are no other versions or options.


The MSRP for this Olight is $99.95.  It’s new enough that the street price is right at the same level.

Short Review

This is a quality light, with an interesting useful new feature – the charging tailcap which retains the tailswitch.  It’s taken me a little time to get used to the UI, but it’s not hard.

Long Review

What’s Included

  • Olight M2R Warrior
  • Nylon pouch
  • Lanyard
  • Charge cable
  • 3500mAh Olight 18650
  • Manual
  • Promotional paraphernalia


Package and Manual

Nothing whatsoever unusual on the outside of this Olight package.  There’s a nice photo of the light, a bunch of specs, and a list of many features.

The inside of the package, however, is quite new.  Olight seems to be trying to work out how they want the “unboxing experience” to flow, and this seems to be the best yet.  Upon opening the box, you immediately get to see the light, but Olight still controls access, with some pointers and requirements before you get to use it.


The manual is good, as Olight manuals are.  There are a bunch of languages included, and no good way to fold them off so you can see the pages you want in the language you want.  It’d almost be nice if the whole thing was front and back so things could be torn off if they were unwanted.  The manual does not seem to adequate cover charging, or the actions of the indicating side switch.

Build Quality and Disassembly

This M2R Warrior has a fantastic heft, and the anodizing is smooth and … this just feels like a quality light.

And the build quality is very good.  The body has a lot going on, to be sure.  Tailcap has it’s own grips.  The tube part has it’s own type of grip.  The switch area has a hexagonal anti-roll shape, and some heat sinking fins.  The head has knurling that matches the tailcap.


It’ll headstand and tailstand.

The parts come off as seen below.  The cell may be removed by unscrewing the tailcap.  The threads here are anodized, properly lubed, and big thick square cut threads.  In fact these are some of the nicest threads I’ve seen in a while.

Inside the cell tube is a sleeve, which facilitates the charging option, and the momentary option.  This tube isn’t directional for operation, but there’s a silk-screened battery direction icon on the inside of it, that you may prefer to be visible.  The side switch will work when this tube is not in the light.  But the momentary switch will not work. Nor will charging, of course.

With a bit of careful pressure on the bezel, the bezel unscrews easily, and the reflector comes right out.


Officially Weight: 149g.  Length: 130mm.  Head Diameter: 25.4mm.  Body Diameter: 24.4.

Essentially a typical tube sized 18650 light.  Slightly longer than the TorchLAB BOSS, likely due to the on-board charging option.


Included is a nice nylon pouch, of unusual design. It has the normal features of a pouch, with a bit of an unusual design – there’s a clip on the front, which holds the flap closed.

The pocket clip is the “new style” with the dual-direction loop, but it can also go on the head or tail end of the light.  So in either position, the light may be carried tip up or tip down.  Not a bad design at all, and it holds on very snugly. Also can be seen in the photo below is the lanyard attachment point on the tailcap.

The tailcap has a magnet as well.  This magnet is strong enough to hold the light horizontally, but the light still slides down.  So the magnet is better for hanging the light.



A single 18650 (or two CR123A) powers this light.  Olight provides a cell, which is claimed to be a 3500mAh 18650.  There are springs on both ends of the light, and the light will work with protected and unprotected, and flat and button top cells.  Below is the cell Olight includes.

It claims to be a “High Drain” cell, and I find that likely.  The lower Turbo (yes there are 2) draws almost 4A, and that’s with a series measure, which is likely low.

Here’s a runtime on Turbo.  (This is the 1000 lumen Turbo).  You can see a very quick decline from Turbo (around 4 minutes to 67%), and then some heavy stepdowns later in the runtime.  I believe these are voltage based, happening around 3.6, 3.0, and 2.7V.  The light does not have Low Voltage Protection!   It will shut off around 2.4V, but that’s likely due to being undervoltage for the emitter, not due to protection.


Fortunately the cell that Olight includes has built in overcharge, undercharge, and over discharge current protection.  Also fortunately, the M2R Warrior has built in charging, and it can ‘untrip’ protection on tripped cells.  That was the case after this runtime.  No other charger I had (at the time I wasn’t testing the MC3000), could revive this cell.  But the M2R had no problem at all.


The charger connects to a regular USB plug.  The light side magnetically connects to the M2R.  Polarity makes it only connect in the right way, too.  Yes, there is voltage across those contacts on the M2R but Olight has “fixed” this from previous generation of charging lights, and there’s nothing to worry about here.

The on-board charging operates at a respectable 0.75A, and as it turns out the 3500mAh claim for the provided cell doesn’t seem to be unreasonable.  I was able to put that much into the cell (at ~3500mAh).  The CC phase of charging is very stable, and the CV phase looks just like it should.  This is good on-board charging.  It is fairly slow though….  Chargetime terminated at 4.21V.


I would willingly give more information about the indicating side switch for both runtime (low voltage) and charge time (cell capacity) but the manual does not seem to cover this.  It could be there, but it seems buried under the 10000 languages, and 42 folds.

User Interface and Operation

There are two switches on the M2R Warrior.  There’s a tailcap e-switch (no this is not a mechanical switch as far as I can tell).



And there’s an indicating side e-switch.  This is the same as the other current generation Olights (read: the s1 mini).  Same feel, same indication etc.


This light has two mode groups: Standard, and Enhanced Tactical.  Switching between them is easy: Hold the tail switch, and press the side switch.  Standard group will display a constant output.  Enhanced Tactical will display strobe.  Click the side switch to move between the two. When in the group you want, release the tail switch.

There’s another way too.  Cycle through the modes with the side switch 3x.  After 3x, the light will alternate as above (turbo and strobe).  Release in desired group, and that sets the group choice.

State (Standard Mode) Action Result
Off Half press tail switch Momentary Turbo
Off Full press tail switch Turbo on
Off  Hold side switch Moon
Off Click side switch On (mode memory) (including turbo and moon)
Off Double click side switch High
Off Hold side switch Moon then lockout
On Hold side switch Mode cycle (L>H direction) (turbo and moon excluded)
On Double click side switch Turbo
Any Triple click side switch Strobe

The two groups are similar except this:  In Standard, a full press of the tail switch activates Turbo.  In Enhanced Tactical, a full press activates strobe.  (In either, a soft press activates Turbo.)  As far as I can tell that’s the only difference.


Mode Mode Claimed Output (lm) Claimed Runtime Mode Measured Lux Tailcap Amps

LED and Beam

In this light is a Cree XHP35 HD.  There’s a very nice orange peel reflector, and a white centering ring.

The beam is a lot of spot will a fairly quick roll off into spill.  This isn’t really a thower, but the spot is fairly useful.  I measured around 200m of throw.

This is a well considered light, of high quality.

What I like

  • Great build quality
  • Indicating side switch
  • Dual switches
  • Tailswitch is different, and great to press
  • On-board charging
  • No need for proprietary cells

What I don’t like

  • No LVP
  • Tailswitch isn’t mechanical (better for standby drain purposes)
  • Tint

Up Next

More lights?  Olight S1 Mini and some other fairly random choices.  RC Car? Maybe soon.  Another charger, maybe soon too!
