Klarus HR1 Headlamp Review
Another Klarus, and this time the Klarus HR1 Headlamp. This is a neat headlamp, with a few battery options, and a few emitters. Read on!
Official Specs and Features
There is only one emitter option, but two bodies. Black (seen here) and teal.
MSRP on these is $49.95, and they’re available on Amazon! (Referral link.)
I’m pleased with this headlamp, and it does work well. It meets or beats specs, has some battery options, and can even be run off a powerbank!

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

Package and Manual
Build Quality and Disassembly
I’m really quite impressed about this light… for a “plastic body headlamp” in the… can we say “hiking” style? it’s very well built. Sturdy, even.
The band is nice, the cables are nice, …. everything’s just nice about this build.
Here on the back of the light itself, you can see a bit of metal peeking through. Good for spreading the heat! Also, see how the light body (very thin!) tilts downward for easy adjustment and beam location.
Size and Comps
• Dimensions: 65.6mm(2.58”) × 30.2mm(1.19”) × 18.2mm(0.72”)
• Weight: 46g (1.62oz) (w/o battery)
Retention and Carry
This is a 100% dedicated headlamp and no option for removal. In fact the light is unusually cabled to the battery on the back – the cable is sewn into the headband to connect to the battery on the back.
The headband is very nice, too. Soft and comfortable, with a soft patch on the back.
That said, it can wear a bit funny depending on your head shape, with the PP20 battery. It sits off the back of the head a little, because it’s just a rectangle – not contoured.
It’s adjustable. At the largest, it’ll be big enough for the biggest heads out there, but just.
Power and Runtime
Power for my HR1 is from the PP20, which is an option – and included at the $49.95 price on Amazon.
This power pack has a button – more on that part later.
It’s also very slim.
This is a 2000mAh LiPo.
There are two ports on this battery. One is USB-C in, for charging, and one is USB-C out. That the battery has both sex USB-C connectors makes it interesting – the light part plugs into the male port on the battery. Conversely, the light’s port is a female USB-C, and that means it can be powered from a USB-C powerbank. Unfortunately, the female port on the battery can’t be used as a powerbank.
Here are a couple of runtimes. Interestingly the High with both emitters is the same as the high on the spot (main) emitter.
And below is why this review is coming at [late:30] instead of the more common Wednesday time; this runtime was just a massive file and my Excel absolutely hated it. I finally just took a screenshot. Hope it’s still useful. ¯_(ツ)_/¯
The light does have a hard shutoff after some stepdowns.
The PP20 has a USB-C port for charging, with a press in cover. The cover is very stable.
An appropriate cable is included. I did not find the PP20 to charge with USB-C to USB-C.
Charging goes along at a respectable ~1A. While charging, the switch on the PP20 is red, and when charging is complete, the switch turns green. It’s a very well lit, even surround, too. The switch also indicates power at turn on, for 5 seconds, as follows:
Red Flashing: <10%
Modes and Currents
The manual really only makes claims for output when both emitters are on. Amps are measured from when the light is being used as a powerbank, but at the least will give some idea.
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
|High – Both||600||4h||656||1.01|
|Medium – Both||150||12h||156||0.23|
|Low – Both||30||32h||31||0.05|
|High – Spotlight||–||–||546||0.99|
|Medium – Spotlight||–||–||140||0.23|
|Low – Spotlight||–||–||31||0.05|
|High – Floodlight||–||–||460||1.01|
|Medium – Floodlight||–||–||140||0.23|
|Low – Floodlight||–||–||31||0.05|
Pulse Width Modulation
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, which is 50 microseconds (50us). 10ms. 5ms. 2ms. 1ms. 0.5ms. 0.2ms. 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 a couple of e-switches on the light body. When wearing the light, the switches are on top. The bigger (“Main”) switch is then on the right, and the smaller (“Side”) is on the left.
Here’s a UI table!
|Off||Click Main Switch (MS)||On (Mode Memory)|
|On||Click MS||Mode advance^|
|Off||Click Side Switch (SS)||No action|
|On||Click SS||Emitter change (Flood>Spot>Both)|
|Any||Hold SS||Red steady|
|Red||Click SS||Previous mode (even if that was “off”)|
|Off||Double Click SS||SOS|
|SOS||Double Click SS||Beacon|
|Lockout||Click either 3x||Unlock|
^ Click within 5s from turn on, modes advance as H>M>L. After 5s of being on, modes advance as H>M only.
^^ When locked out, clicking either button activates Red on very low 3x.
It’s possible I missed something here…. the UI is quite comprehensive.
LED and Beam
Both white emitters are Cree XP-G2. One’s Neutral White (the larger TIR Spotlight) and the other’s a Warm White flood TIR output. There’s also a small, all flood red emitter.
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.
Both, spot, flood, then red.
I compare everything to the Killzone 219b BLF-348 because it’s inexpensive and has the best tint!
What I like
- Use of USB-C
- Meets specs
- Mix of emitters having the same output is a weird choice
- Dual Switch UI is convenient
- Battery options (including AAA!)
- Can run off a powerbank
- Reasonable tilt adjustment on light body
- No flappy bits, so good for running
What I don’t like
- Powerbank on the PP20 would be great!
