Olight Marauder 2 Blue Flashlight Review

Olight Marauder 2 Blue Flashlight Review

The Olight Marauder 2 Blue is an Osram flat white thrower, with secondary emitters (12) for flood. And both perform exceptionally! Read on!

Official Specs and Features

Here’s a link to the Olight Marauder 2 Blue product page.


There’s really just one version of the Marauder 2, in the sense that all the body colors have the same emitters.  There are three body colors though – Blue (seen here), Black (still available), and Orange.

Each of those three is available in a different kit – with or without the wall wart.



These were going for $349.95 when available, but the blue is sold out.  It was also possible to purchase the light for less, without the power adapter.  Around $30 less.

However, the Olight Marauder 2 in black is still available and is actually less expensive: $329.95.  These are referral links.  This helps Olight know to continue sending review lights to me!

Short Review

The best summary of this light is that this blue version was on loan from a friend, and I liked it enough to buy the orange version when it came out.  Do I need to say more?

Build Quality and Disassembly

feature photo on side

This light has a fantastic heft.  The color is great and looks to be of high quality.

Here’s the top-down view.

Atop the Olight Marauder 2 Blue is this strike bezel.  The Blue version has a black bezel (and otherwise, black trim) as does the Orange.  But the black has blue trim.

On the end of the Olight Marauder 2 Blue is all this printing, which details the battery that’s built in, and other aspects.

tail end

More about these switches later, but first just check out the novelty.  There’s a rotary switch for controlling the modes, and a flip switch that controls which emitters is on.


The lenses here are very … clear?  Sharp?  Neat?  Unusual?  There are all sorts of words you can use, but they’re cool that’s for certain.


As this was a borrowed and not a review light, and since others have done it before anyway, I didn’t disassemble it at all.  It’s possible, though.

Size and Comps

Weight (g / oz) 750g / 26.5oz
Length (mm / in) 140mm / 5.51in
Head Diameter (mm / in) 79mm / 3.11in
Body Diameter (mm / in) 53mm / 2.09in

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.

Here’s the Olight Marauder 2 Blue beside the Fenix LR40R, which I previously reviewed.  These two are very solid competitors (and I’m glad to have both!)

Retention and Carry

Primarily you’ll be carrying this light by means of the lanyard, which attaches on this “coin slot loop.”

The little loop flips out of the body and has a little thumbnail nick to help with access.

Here’s the included lanyard.  It’s nice and can be very long if unraveled.


There are no other means intended for carrying the Olight Marauder 2 Blue.  I will mention the grip along the body, however.  This is a sticker-type grippy pad and does provide extra, or substantial grip.  It’s also a grime magnet.

Power and Runtime

Inside the Olight Marauder 2 Blue is a battery pack built of individual 21700 cells.  There are three 21700 cells, and they’re in series (hence the “10.8V”).  This is good for a number of reasons, but more on that below.

tailcap power details

I didn’t take these cells out, but having seen them I wouldn’t call this to be a “replaceable” setup.  That is a definite downside.

Here are some runtime graphs.  I tested a few of the Spot modes and a couple of the flood modes.

In this first graph (Spot Level 7), the temp sensor fell off the light at around 80 minutes, so disregard that section.

Output steps down a bunch on most modes, but 85 minutes or so at 800 lumens of 800m of throw is pretty great anyway.

spot runtime level 7 spot runtime level 6 spot runtime level 5

The modes are very flat throughout, which is great.

Here are a couple of the flood modes.  Level 7 has a massive stepdown but is within 10% of the claim which for me is close enough (by that I mean, I allow 10% or so because I’m an amateur).

flood runtime graph level 7

On Level 6, you can see the temperature get quite warm, until the stepdown.

flood runtime graph level 6


The Marauder 2 has on-board charging.  This is a USB-C port in the tail and is accessible via twisting the tailcap.

This is a neat mechanism, and the light has an IPX8 waterproof rating, so it must be a “good enough” seal.

charge port aperture

Included with the “bigger” package is this wall wart.  It’s a 30W wall wart and has only one USB-C port.

This charger (or at least one like it) is positively recommended for the Olight Marauder 2.   I can’t even say for certain that USB to USB-C will charge the light.  I tried it and it took ‘forever’ (and maybe didn’t complete, I don’t rightly recall).

Also, this charging is PD charging – it’ll charge at up to 20V.  And with the included charger, it does charge at 20V.

30W wall wart usb-c

As it states, it’s a 30W charger.  So at 20V, that’s over 1A, and charging is amazingly quick!

30W wall wart

An appropriate charge cable is included – USB-C to USB-C.

Unfortunately for me and you all, I killed my USB-C logger and wasn’t able to record any charge cycles from this light.  I did note it, as I said, at about 2.5 hours (which is just fantastic).  It surprised me every time to note that it was already completed charging.

There’s a charge status indicator on the indicator around the rotary switch.  Right in the center is a single dot (the rest are dashes).  When solid red, the light is charging.  When solid green, charging is complete.  When flashing green, the charge port is being used as a powerbank.

That’s right!  The Olight Marauder 2 Blue can be used as a powerbank, too!  As with the charge logging, I wasn’t able to log the powerbank data.

Pulse Width Modulation

The spotlight (listed first), does not have any PWM at all.

The flood emitters have pwm on the lower four (maybe 5) modes.

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

There are two switches on the Olight Marauder 2.  First is this rotary switch.


Not only does this switch serve as a dial, it’s also clicky.  There’s a fair bit of action on it, too.  Travel is around 1.5-2mm.

switch in use

When actuated the indicators light up as seen below.  To the right side of the switch is the battery indicator.  To the left is the mode.  In the photo below, the battery is at level 7, and the output is at level 1.

indicators around switch

There’s a second switch, too.  It’s this little toggle, which switches between flood and throw.  The rotary doesn’t care which way the toggle is; the rotary UI is the same.  On the toggle, “up” or “forward” is the Spot emitter, and “down” or “back” is the flood.

Here’s a UI table!

State Action Result
Off Click Rotary Switch Battery indicator (if the light has been off >30s)

Unlocked Click Rotary Switch On in previously used level.  (Level can not be changed while output is off.)
On Rotate Switch Clockwise Increase output level
On Rotate Switch Counterclockwise Decrease output level

LED and Beam

According to Olight the throw emitter is an Osram KW CULPM1.TG 8R, and the flood emitters are Osram P9.  The throw emitter is deep inside, and projected by an actual projection lens.

lenses for emitters

This setup is extremely efficient, causing a ton of throw out of the single emitter.  While the projector lens does protrude (ie the front here is not “flat”), it doesn’t protrude past the bezel.  So there’s no harm placing the light face down on a surface.

Also note in the image above, you can see the proximity sensor.  It’s at around the 1 o’clock position in one of the optic legs. This sensor will step the light down any time there’s sufficient bounce from reflected light.  This should prevent you from burning a hole in your [anything].  But it’s a massive hassle for runtime tests, I can tell you that. 😀  However it can be turned off!

lenses for emitters

The flood emitters have their own little TIR type lenses.

Below you can see the light in Spot setup (check the toggle), with a full battery, and on Level 4.

And below, with all the same things except now on Level 1.

Up close, the spot emitter is pleasantly rounded.  At any distance (say, 2 feet or more), however, the projection of the emitter turns square.

spot near range (circle)

in hand

Some users will positively hate this square projection, and on some lights it really is a down side.  But while this is a very square output, it’s still quite neat.  As long as you know what you’re getting, then this will be completely acceptable.  It’s not really quite like the normal cheap zoomies, but I can’t put into words exactly why it’s different.

Also note that the light doesn’t fade from flood to throw – it’s either flood or throw, and there is no middle ground at all.  Flood or throw.  The outputs can not be used simultaneously.  This is a difference from the Fenix LR40R, which can use both output types at the same time.

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!


What I like

  • High-quality build
  • Very fetching blue!
  • USB-C charging at 20V
  • Powerbank feature
  • Massive throw!!  And sustained, too.
  • Output specifications are met
  • Rotary dial is a nice interface for the 7 levels.

What I don’t like

  • Cost
  • Battery is not user serviceable
  • Osram P9 emitters are cooler (and maybe greener) than I like
  • Necessary lockout, without my choice
  • The scheduled stepdowns are quite annoying on the higher modes.
  • The rotating switch is not quite grippy enough for me to use one handed.


  • This light was loaned by a “friend from Ala-freaking-Bama” (his words) for review.  I was not paid to write this review.
