Thrunite TH30 V2 Headlamp Review

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

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: 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

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 the 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 is 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.

Charging

The TH30 V2 has onboard 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!

Here you can see a “baseline” – a chart with almost no light hitting the sensor.

Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.

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 user interface 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)

Beamshots

These beamshots always have the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.

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.

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

Conclusion

What I like

• Output is ridiculous for a headlamp!
• user interface 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
