JETBeam has a new headlamp available – the HR10.  It’s a complete package (cell included) and has built-in, USB-C charging, and an indicating switch!  Read on for more testing of this full featured headlamp.

Official Specs and Features

This light doesn’t seem to be on JETBeam’s page yet.  Here’s my affiliate link to BangGood for the light.


As far as I can tell, there’s only one version.  The manual states the emitter is XP-L HD though, and every other source seems to reference it being XP-L HI.  I’m not sure if that’s a version option, or just an error.

Price and Coupon

This one is going for $50.48 on BangGood, where I got mine.  Buy yours there, through this affiliate link!

Short Review

Solid little headlamp!  I wish the documentation stated specifically that the USB-C port is waterproof, though the light as a whole is IPX7 rated (30 minute, 1m immersion).

What’s Included

  • JETBeam 850mAh 18350
  • Pocket Clip
  • Spare o-ring
  • Charge cable (USB to USB-C)
  • Headband

Package and Manual

Build Quality and Disassembly

The anodizing here feels great in hand.  Very smooth.  This also translates well to getting the light in and out of the headband.

The threads on the tailcap end are unanodized.  Notice in the tailcap there… there are some parts you’re going to want to be careful not to lose.  In fact this isn’t even the recommended way of swapping the cell – remove the head for that.

The head end has anodized threads.  They’re square cut, and kind of long, with good lube coverage.  It’s possible to mechanically lock the light with just a very small loosen.

The head has a nice spring, and the tail end has a button, which seems to have a spring underneath.

Size and Comps

Officially: 79.5mm long, 32.7mm in body diameter, and 21.5mm in head diameter.  (My measurements indicate they have “head” and “body” diameters backward).

Also I think this is the only spot you’ll see them in this review, but see the shot of the top of the head, above.  That is three tritium slots!

Retention and Carry

It’s a headlamp, so that’ll be the main way to carry it.  The included strap is good, with only an around-the-head and not over-the-head strap.

The holder is silicone and the light slips in easily.

There’s no special or extra padding on the back of the light holder, but it’s comfortable enough, being silicone.

The band does not have any grippy for the forehead, but is adjustable.

Technically the light fits into the holder with the pocket clip.  It may even be removed with the clip on.

The pocket clip is a friction fit clip, fitting only on the head end allowing “head up” (but “bezel out”) carry.  The clip is fine, and probably thicker metal than usually seen in this type clip.  It has the style of clips typical to Lumintop.

The pocket clip gets in the way of unscrewing the head just a little (enough to scratch the head, though!)

There’s also a lanyard hole in the tailcap.


Power and Runtime

Power is provided to the HR10 by a single 18350 Liion cell.  This is a regular button top cell, despite the light also offering on-board charging.

Note that the cell has both positive and negative terminals on one end.  That’s what allows charging inside the HR10.

The light requires the cell be in reverse orientation from normal.  The negative terminal of the cell is toward the head of the light.

Here are a couple runtimes.

The light shuts off cleanly at a high-ish 3.2ish volts.  There’s also a voltage indicator just beside the charge port (seen below).  When the cell is below 10%, the indicator will flash red.

The charge port is a USB-C port, and does not have a cover.  The light still states IPX7, which is 1m immersion for 30 minutes, so I have to suppose that this is a waterproof USB-C port (something that does exist).

An appropriate cable is included:  USB to USB-C.

Charging looks good and more importantly is consistent.  Charging is at near-1C.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
High 700+280 3m+1.7h 685 1.47
Middle 280 1.8h 280 0.45
Low 75 7.7h 78 0.11
Eco 6 60h 3 0.02

Pulse Width Modulation

No PWM is seen.

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

There’s one switch on the HR10 – an indicating e-switch on the head.  This switch isn’t opposite the bezel, it’s 90 degrees to it.

Here’s a UI table!

State Action Result
Off Click On (Mode Memory)
On Click Off
Off Hold Eco
On Hold Mode advance (LMH only)
Any (unlocked) Double Click High
Off Long Hold Eco then off then Lock (signified by two flashes of “Low”) –
Locked Click Switch blinks red to signify Lock
Locked Long Hold Unlock to Low

There are no strobes or special modes!

LED and Beam

The emitter is a Cree XP-L HD.  The manual I have states this accurately.  Every sales item I’ve seen states XP-L HI.  BangGood does too, and their product photos show XP-L HD as well.

This emitter is behind a TIR optic.  The beam profile is quite a bit of spot.

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 (Killzone 219b version)

Test light is on the left.

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


What I like

  • Complete Package
  • Hits specs for throw and output
  • USB-C Charging
  • Indicator
  • Cool white emitter
  • HD emitter instead of the promoted Cree XP-L HI
  • Tritium slots are fun

What I don’t like

  • Pocket clip gets in the way of unscrewing the head just a little (enough to scratch the head)
  • Cell is proprietary

    1. I guess you mean “flat top” 18350…. what’s included is a “normal” 18350 as well, just a button top variety. Yes, a flat top 18350 should work no problem.
