Thrunite TH30 V2 Headlamp Review

Thrunite TH30 V2 Headlamp Review

The Thrunite TH30 headlamp has been updated to V2! They added USB-C charging, and use the great Cree XHP70.2 emitter – mine is neutral white!

Official Specs and Features

Here’s a link to the Thrunite TH30 V2 headlamp product page.


Two versions.  One is cool white, and one is neutral white.


These go for $79.95 currently.  You can purchase the Thrunite TH30 V2 headlamp with 20% off (or $69.95) on Amazon (referral link.)

Short Review

This headlamp lives up to the claims Thrunite makes! I like the full package nature of it, and overall it’s just a solid contender.

^ Measurement disclaimer:  I am an amateur flashlight reviewer.  I don’t have $10,000 or even $1,000 worth of testing equipment.  I test output and such in PVC tubes!!  Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

Package and Manual

Build Quality and Disassembly

This is a well-built light, with a couple of nice touches that make it stand out.

There are some minor aesthetic updates to the V2 of the TH30.  We lose the knurling – that’s probably the most immediately noticeable change.  I reviewed the first TH30 a while back, in case you want to check that one out!

The head design has changed a bit too.  Gone are the very deep cooling fins.

On the tailcap there’s a nice beefy spring.

Check out how short those threads are!  Very minimal twisting is required to secure the tailcap.

The head end has only a brass button for contact.  No issues there though – the tailcap spring keeps things snug.

Size and Comps

107.5mm x 25.5mm x 24.5mm.  The weight is 70g without cell.

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight 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 formats.

Retention and Carry

The primary means to carry this light will be the headband.  The strap is a nice rubber (silicone?) band.  The light has smooth indentions which hold the light tightly but still allow the light to rotate, too.

Secondly, the light can be used with a pocket clip.  The clip isn’t deep carry (at all) but will go on the head or tail end.


Power and Runtime

A single 18650 runs this headlamp.  The button on the positive end would cause no problems using any type of 18650 (button or flat).  Do be aware that Turbo requires a lot of the cell (around 8A), so you need to use a high-quality cell for this light.

Below is a runtime on Turbo.  The temperature spikes a little at first, but the stepdown is quick.  Once the stepdown has happened, it’s possible to hit Turbo again, but the light doesn’t quite hit the initial output.  Once the stepdown has happened, the light maintains extremely steady output at a level just lower than “High.”

Note that I’m measuring the output at over 2500 lumens at 30 seconds.  And still practically 1100 lumens after the stepdown!

There are two indications of low voltage from the light. First, the switch has an indicating feature.  It indicates as follows:

Blue: 21-100% power
Red: 11-20% power
Flashing Red: 1-10% power
Off: 0% power

Secondly, the main emitter blinks when the voltage gets low.  You can see that in all the runtime graphs.


The TH30 V2 has on-board charging, too.  The head has a USB-C port, which is covered by a rubber boot.  The boot is a little long and flexible for my tastes, but at the same time, does seem to stay very well put.

Charging works well, and the CC phase is 1.2A or over for the duration.  It’s also very consistent (note that there are two tests shown below, and they’re indistinguishably similar).

While charging, the switch LED indicator is red.  When charging has completed, the switch turns blue.

C to C charging works great too; the chart looks about the same as above.  A graph is below.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 3320/853 2m/110m 2536 7.89
High 1256/867 4.5m/111m 1295 2.13
Medium 345 5h 348 0.49
Medium-Low 131 13h 122 0.17
Low 30 55h 22 0.03
Firefly 0.3 29d 0.2 3.40mA

Pulse Width Modulation

There is no PWM on any mode!

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, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  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

The TH30 V2 has a single switch on the head.  It’s an e-switch, with two indicating emitters; red and blue.  The switch is held in place by a bezel I couldn’t remove (not sure if it’s screwed in or press-fit, but there are no reliefs, so it’s likely press-fit) This might not seem like a big deal but have a look at it below.  It’s very smooth and great for button-pressing-comfort.  I would call this an improved switch over the original TH30, too.  It’s bigger and less recessed.

Here’s a UI table!

State Action Result
Off Click On (Mode Memory except for Firefly, Turbo, and SOS)
Off Hold Firefly
Any Double Click Turbo
On Hold Mode Advance (L, ML, M, H) (No Firefly, no Turbo)
Any Triple Click SOS
On Click Off

There is no strobe!

LED and Beam

The emitter in this TH30 V2 is a Neutral White Cree XHP70.2.  The reflector is a fairly shallow orange peel reflector.


LED Color Report (CRI and CCT)


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)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

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


What I like

  • Output is ridiculous for a headlamp!
  • UI is very simple and pretty good.
  • Build quality is good
  • Full package is included
  • Hits the numbers (throw and output)
  • CCT report does support the NW claim
  • Updated to USB-C charge port

What I don’t like

  • Big stepdown from the initial output

  1. How green does this NW look?
    I wish they’d start offering different body tubes, eg 18350.
    Soon enough I think powerbank functionality will be expected with 18650 and 21700 premium lights that have USC C charging.

    1. I wouldn’t describe the NW as green at all. Maybe on the middle two modes, a little bit though…. I think the beam photos describe it.
