Olight Perun 2 Headlamp Review

Among other limited editions Olight has recently introduced was an orange Perun 2.  Not only is the orange a limited version, but the Olight Perun 2 21700 LED headlamp is a new light!  It has a proximity sensor, and offers built-in (magnetic) charging.  Read on!

Short Review

As a headlamp I don’t dig this light so much.  It’s too big and heavy for great use on a forehead.  As a handheld right-angle light, this is pretty good.  I do not like the sensor, and it really gets in the way of my normal use of the Perun 2, but if you don’t see yourself using the light on higher modes up close, this might not be a problem for you.

Build Quality and Disassembly

Build quality is great.  The orange is very good orange anodizing.  It matches the other orange Olights very well.

The head has some deep cooling grooves.

The body has the triangle “knurling” Olight’s been playing at lately, and some cross hatch swirling down the side.  It’s an interesting design.

The tailcap carries the swirl theme.

In the head you can see the emitter and also the little sensor.  This sensor is used to dim the light when there’s a lot of bounce back light.

An angled head absolutely prevents headstanding.

Only the head comes off the Perun 2.  It’s really a 2 piece body – head and cell tube.  The threads are pleasantly short, and don’t require a ton of effort or twisting to remove.

There’s a spring in head and tail.  An interesting vibration low voltage warning is featured in this light, and that seems to be located in the tail not the head!  (That is based on testing with the bench power.)

Size and Comps

Weight (g / oz) 161/ 5.68
Length (mm / in) 120.7 / 4.75
Head Diameter (mm / in) 28.6 / 1.13

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).

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 format.

Like I said above, the orange on these lights really works well.  And matches well too!

Retention and Carry

The light ships with this pocket clip installed, so I’ll consider that the primary carry option.  It’s a friction fit two-way clip, and does work well.

The clip is clearly intended for the one location it’s already installed, but it also fits on the wider bands on both the head and tail.

Next is the headband.  The headband can be used at the same time with the pocket clip, but it’s a bit cumbersome.  Ideally you’ll probably want to remove the clip before using this as a headlamp.

A nice headband is included.  It has a silicone connector into which the Perun 2 slips, and a useful tab on one of the loops is included.  One strap goes over-the-head and this strap is not removable.  It’s permanently attached on the front.

And as you can see below, also permanently attached on the back.

You’ll likely want that anyway – the Perun 2 is large enough you’ll need the extra support.

The headband also has some reflective strips.

Inside the headband is only soft fabric – there are no silicone grippy strips.

Final mention is the magnet.  Yes, this magnet is primarily used as a charge base connector, but it’s surprisingly strong enough to hold this long heavy light horizontally.

Power and Runtime

Olight’s Perun 2 is powered by a single lithium ion cell.  A cell is included at all purchase levels of this light.  It’s the 4000mAh customized, proprietary 21700 cell.

olight perun 2 21700 headlamp orange headband 4000mAh 21700

This cell has a plastic shroud around the positive terminal, and also has an exposed negative terminal on the positive end, too.

This shroud is tall, and will prevent the cell being charged in most bay chargers.

Installation of the cell is opposite to what I call the “usual” way.  The positive terminal goes into the body, and the negative terminal is toward the head.

Here are a couple of runtimes.  Since the bounce feature is so…. aggressive…  I can’t do my normal calibrated runtimes.  So I’ve set the 30 second reading to what Olight claims, and the rest of the runtime profile can still be useful.  The vibration warning for low voltage is interesting.

Same as above – due to the bounce sensor, this is an uncalibrated runtime, which I have set the 30s value to what Olight claims.  Output is extremely well regulated!

olight perun 2 21700 headlamp orange runtime graph high

I stopped both tests when the vibration warning had been happening for a few minutes.

The charge connector is the same as other recent Olights.  It’s the MCC charger, and on this light goes up to (or over) 2A charging.

olight perun 2 21700 headlamp orange mcc charging base

Charging takes around 3 and a half hours, which is pretty good for a 21700 cell!  Notably the green charge indicator on the charge connector turns green long before the current stops, but even then the cell is at 4.15V or so.  So it’s good or good enough.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 2500/32%/20% 2m/130m/45m 6.31

PWM

No PWM on any of the 5 modes.

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 button controls the Perun 2.  It’s a big pad of an e-switch, and sits at an angle on the head.

olight perun 2 21700 headlamp orange button profile

This angle does completely prevent headstanding.

The switch has a power symbol, and is quite large and easy to find.  Actuation is very positive but absolutely only in the center of the button.  That is, within the power symbol seen below.

Here’s a UI table!

LED and Beam

Olight went with a Cree XHP50.2 in a cool white for the Perun 2.  The light utilizes a TIR, with a cutout to allow for the sensor.

olight perun 2 21700 headlamp orange emitter

Unlike some of the other Olight sensor based lights, it’s not possible to turn the sensor off.  And it’s not possible to cover the sensor as a means of disabling it (in fact that’ll do the opposite here – make it ultra aggressive.)  So the sensor is a real deal breaker on this light for me.

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!

Conclusion

What I like

  • Orange light!
  • Complete package
  • Sensor is very effective (and good if you’re looking for a sensor light to prevent a lot of reflected light)
  • User interface is easy to memorize (or just guess)
  • Great build quality
  • Good for hands free use (as a headlamp or using the magnet)

What I don’t like

  • Customized and proprietary cell
  • Proprietary charging (but at least it matches other recent Olight charging lights)
  • Probably not the best choice as a running headlamp

  1. Very good review! The only thing I can not really understand is why the sensor is a deal breaker. From what I understand, it is a proximity sensor. It dims your light to ‘low’ when you run it in a high setting and there is a surface directly in front of it (~20cm?), so you do not drain your light in your pocket/backpack or even burn your stuff (which this light is very capable of in turbo mode!). Also, if the sensor notices an obstruction without movement for a minute, the light turns off. I never run into situations, where I need maximum brightness close to a surface. I have yet to try if I can run my light in a lower setting with some kind of diffuser for passive flood light without it turning off. However, I can understand that this feature obstructs testing.

    I also really like the magnet, but it only really seems to hold the lights weight directly on proper metal (car, radiator, etc.) It did not hold up on my whiteboard.

    Thank you for your review!

    1. I really don’t want a light to decide for me when there’s too much bounce back, or the reflection is too bright… etc. I want to decide those things for myself.
