The Olight OPEN 2 EDC pen is the second edition pen from Olight, and a refinement of the first.  The bolt action pen features a side emitter, and an e-switch. Read on!

Official Specs and Features

Here’s a link to the Olight OPEN 2 EDC pen product page.


Just two versions as far as I can tell.  Blue (seen here) and black.


The Olight OPEN 2 EDC pen is selling for $59.95 at the moment.  You can buy yours at OlightStore.com – that’s my referral link!

Short Review of the Olight OPEN 2 EDC pen

I don’t love bolt action pens, and certainly not ones which have the action so low on the barrel.  I will say, however, that the ability to separate the light from the body and have usable [both parts] is pretty clever.  This does, however, mean that when used as one, the whole thing is very long.  Also I appreciate USB-C charging, and also that the flashlight part hits the claimed specifications.  All in all, it’s a solid effort, just not one I’d buy.

Build Quality and Disassembly

The build quality here is good, and fairly standard fare for Olight.

The ink comes wax tipped, and sealed.

Olight does sell refills, too.   I’m unsure if this is a standard cartridge, or if you’ll have to get refills from Olight.  I have a suspicion that this ink is proprietary….

The threads between the flashlight part and the body part are very smooth.  They’re’ anodized, and lubed.


The charge port is protected by a seal when the parts are screwed together.

The tip also comes off easily.  Same threads but the diameter of the piece is a little narrower than the flashlight half.  Removal of the tip is how you’ll swap inks.

Size and Comps

Weight (g / oz) 38 / 1.34
Length (mm / in) 145 / 5.7
Tip Diameter (mm / in) 0.6 / 0.024
Body Diameter (mm / in) 12.7/ 0.5

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

Like I said, for use as a pen, and when all as one piece, it’s quite large.

Retention and Carry

The pocket clip is the only real means of carry for the Olight OPEN 2 EDC pen.  It’s a decent enough clip, but features a proprietary removal screw.  It’s a bit stiff, and also a bit difficult to get over a pocket – the mouth is quite small.

Note that there does appear to be a slot for tritium in the clip, which is an interesting touch!

Power and Runtime


The Olight OPEN 2 EDC pen is powered by an internal cell, which Olight states as a 110mAh battery.

Here are runtimes for the three higher modes.

Nothing too exceptional, but noteworthy that the specs are in fact hit!


The OPEN 2 features USB-C charging.  The charge port is hidden between the pen halves.

An appropriate cable is included.  It’s a very short USB to USB-C cable.

Charging looks good, and does not require a full hour to complete.

While charging, the red LED is lit.  When charging is complete, the red indicator goes off.  There is no other indication that charging is complete.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
High 120 20m 130 ?
Medium 60 40m 72 ?
Low 20 2h 25 ?
Moon 5 8h ?

Pulse Width Modulation

There is PWM on every mode.  Such PWM, that I had to change my timescale just to show a complete cycle of it.  The PWM is so slow you’d think it would be terribly visible but surprisingly it’s not actually.  It is visible, but not oppressive.  First, the normal timescale:

And now the timescale where you can see a full cycle:

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  And here’s the worst PWM light I have ever owned.  Also one of the very first lights I ordered directly from China!

User Interface and Operation

A single e-switch operates the Olight OPEN 2 EDC pen.  It’s in the tail, and is very proud.  It prevents tailstanding, too.


Despite looking like a pen clicky, it’s not at all. The pen is completely controlled by the bolt action.  This tail switch is only for the flashlight.

Here’s a UI table!

On Click Off

LED and Beam

Though Olight doesn’t state what emitter is used in the OPEN 2 EDC pen, based on other Olights I have I’m fairly confident this is an Osram P9.


There’s a diffusing window, and the output is entirely flood.  That red emitter seen below isn’t usable as a red secondary, unfortunately.  It only indicates charging, and lockout.

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)

Test light is on the left!

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


What I like

  • Hits specifications for Output
  • Also hits specs for throw
  • Good combo when used as individual parts
  • Build quality is good
  • USB-C charging
  • Simple user interface, and Moon is the default
  • Pocket clip has a tritium slot (!!!)

What I don’t like

  • Bolt action
  • Overall size
  • Price
  • Pocket clip hard to use
