In my hands today is a new headlamp by Wuben.  This is the H1, an 18650 light with two white emitters, and red.  Read on for some thoughts and testing!

Official Specs and Features

Here’s a link to the official product page.


I believe there is just one version of the H1.


These are currently on sale for $32.99, down from the MSRP of $49.99.

Short Review

This is a solid little headlamp, especially at $33.  I would probably pick something other than the Osram P9 emitter, but again, for the price this is hard to beat!

Package and Manual

Build Quality and Disassembly

One random thing I happen to really like on this little headlamp is the tailcap knurling.  It’s very grippy but also not deep.  Almost looks decorative, except that it’s extremely useful.

These lights are surprisingly serialized.  The Open/Close text is a little superfluous.

The end with the switch is also the end with the charge port.  The switch cover is connected to the charge port cover.

I find the threading on this tailcap to be unusual.  The threads are very big, and it takes only ~1.75 turns to remove the tailcap.  I like this aspect.

The tail cap has a spring, but there’s just a brass button in the cell tube for contact.

The cell tube also has these deep grooves.  I’m not sure what these are for exactly, but I’m sure it’s related to indexing the guts on the front.

Size and Comps

Size 85mmx 26mmx 33mm
Weight 54g without battery


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.

Retention and Carry

This is a headlamp, and likely won’t service as much else.  The light being directly in the center of the side means it’s not a typical “right angle” light.

The headband has grippy silicone over all the parts that touch your head – around the sides and over the top.  The over the top part isn’t removable

The headband is comfortable and grippy.

The top strap is an integral part of the system.

The light slips into these silicone holders fairly easily.  These are slightly more stiff than other brands, but do seem quite snug and secure.

There is no other means of carrying the light.  There isn’t a pocket clip or magnet.

Power and Runtime

The Wuben H1 is powered by a single lithium ion cell.  An appropriate 18650 is included by Wuben.  It’s named the ABE2600C.

This Wuben cell is not required – any 18650 should work.  There is adequate length for longer 18650 cells, and adequate spring for the shortest unprotected flat tops.

It’s a button top cell, but standard.

The light has a battery status indicator, too – when the light is turned on, for 5 seconds the secondary emitter indicates as follows:

Blue Steady: ≥90%
Blue Flashes: 90% to ≥40%
Red Steady: 40% to ≥15%
Red Flashes: <15%

Here are a couple of runtimes.  The manual says different things in different languages, but in the English part, the highest mode mentioned is “High” (and not “Turbo” as in other parts of the manual.  So I’ve labeled the graphs according to the manual.  High steps down dramatically after around 30 seconds, but gets fairly near the claim of 1200 lumens.  And not only that, it’s holding the 1120 or so lumens very steady for those 30 seconds.  Little consolation, but some.  After the stepdown, the output is extremely stable, until a low voltage termination.

Medium is equally as stable, and also shuts off with LVP.

As stated, the H1 has on-board charging, by way of a micro-USB port.  A cable is included:  USB to micro-USB.

The charge port cover is just a press-in cover.  Seems secure enough, though.

Charging looks very good, at around 1A in both tests.  Charging is to 4.20V, too (which some lights fall short of).

While charging, the red secondary emitter is constant.  When charging is complete, the secondary emitter is blue constant.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
High 1200/500 1m/2h 1118 3.40
Medium 400 2.6h 413 0.84
Low 80 14h 87 0.16
Moon 1 500h 0.02
White Secondary 10 25h 0.09
Red Secondary 10 30h 0.07

Pulse Width Modulation

There isn’t really PWM on any mode, but the middle two modes on the main light do have a bit of sawtoothing.  Nothing to worry about though.

White secondary:

Red Secondary:

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

The Wuben H1 is controlled by a single switch, which is on the same end of the light as the charge port.  The switch is highly textured, so it’s moderately easy to differentiate the charge port cover from the switch.

Either way they’re small enough that giving the whole tailcap a smash gets the job done.

Here’s a UI table!

State Action Result
Off Click On (Main emitter, mode memory)
Off Hold On (Secondary emitter, mode memory)
On Click Off
On Hold Mode advance (Moon,L,M,H for main; White, Red, Red Flash for secondary)
On (but not in Turbo) Double Click Turbo
Off (or secondary emitter on) Double Click Strobe
Strobe Double Click Strobe Advance (Fast strobe, SOS, Beacon)
Off Triple Click Blue breathing secondary emitter
Turbo Double Click Strobe
Off Click 4x Lockout (Signified by 3x flash of main emitter)
Lockout Click 4x Unlock to Moonlight

LED and Beam

The main emitter is an Osram P9, with a small smooth reflector.  It’s cool white.  The secondary emitter area is to the right of the main emitter in the photo below.  Behind this opaque cover is a neutral white, red, and blue emitter selection. These are of course all flood and details about them aren’t included.

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

Tint vs BLF-348 ( 219b version) (affiliate link)

Test light is on the left!

Red Secondary:

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


What I like

  • Low price
  • Complete package
  • Very easy user interface
  • Good and stable headband
  • Very nice tailcap
  • Charging is reliable
  • Charging (or use) is not proprietary

What I don’t like

  • CW main emitter
  • Access to blue (used for breathing and battery check) in the secondary mode group would probably be fun.
