Gear Review: Olight Perun 2 Headlamp / Flashlight


The capabilities of headlamps just keep improving and improving, blowing my mind what an incredible tool some companies can pack into a small little item. The Perun 2 by Olight is a prime example of this. Just released, the Perun 2 is sure to be key player in the headlamp market for hikers with its insanely high lumen output and hiker-specific features like an SOS function and waterproofness.

Pros / What I Like

It’s so bright!
2500 lumens? I mean, come on! That is next level. Precisely what a hiker needs for dark nights in the forest. Granted this power level doesn’t last that long (see specs above), but a super high lumen output still does, and you rarely need 2500 unless you’re calling for help or doing the searching yourself, which bring me to my next point.

SOS Feature
Quickly press the power button three times and it shines a bright light in SOS mode – three long, three short, three long. This is an excellent feature for hikers if you ever get lost or need help. Many hikers don’t know the SOS signal so this takes the guesswork out of it.

Here in the PNW, it’d be silly to buy a headlamp that isn’t at very minimum water-resistant. Oddly, many headlamps on the market fritz out with a little bit of moisture. And we all know that here in Vancouver, we don’t just have a little bit of moisture, especially in the winter when we use headlamps much more often given the shorter days. The Perun 2 is IPX8 rated, meaning it is full waterproof. You could technically dive down 1.5 meters with it on, albeit just for a short time. But that demonstrates it can withstand hours of hiking in the rain.

USB Rechargeable
With the state of the world, it is so important to do as much as we possibly can to avoid waste such as limiting our consumption of disposable products. The standard for a long time with headlamps has been battery-powered. Having USB-rechargeable equipment like this headlamp is so important to me. External battery packs or even solar charging panels can always be carried for longer trips to recharge.

Low Battery Warning
The light will vibrate every 30 seconds when power level is less than 10% so you know it needs to be recharged.

Smart Sensor
It has a built-in proximity sensor to decrease the brightness level in case of obstruction for safety.

I really dislike single-use items. Having a trillion things laying around the house taking up space is not my jam. So I quite enjoy that this is essentially a flashlight as well as a headlamp. So it can be your emergency flashlight for when the power goes out, or used for various activities requiring a flashlight like some jobs. The flashlight can clip to your pocket if your head isn’t accessible (you’re wearing a helmet and hood ie). There are lots of hands-free options with this.

Cons / What I Think Could Be Better

Product-specific charging cable
This headlamp is charged with a magnetic attachment that is specific to this product. I personally prefer when products use standard attachments like USB C or Micro USB B to limit the amount of cables we need to keep and can re-use for multiple products. It does, however, decrease charging time compared to traditional cable charging.

Weight and size
Let me preface by saying the weight, nor the size, are terrible. They are perfectly adequate for hiking, and absolutely understandable given what this baby can do (I doubt you could get the same output in a lighter weight in an even a remotely similar price range). However, it does need to be mentioned as the average hiker typically uses a lightweight, plastic headlamp, which feels leaps and bounds lighter than this one, BUT at the expense of the brightness and range of light and durability, so the benefits absolutely outweigh them. Headlamps of this quality are always this range of size and weight.

Size comparison with a couple of my other headlamps

Having a good-quality headlamp is one of the Ten Essentials because it is so important for your safety as a hiker. It also allows you to get out and safely enjoy nighttime hiking, which is oh so much fun!
