Wurkkos TD02 Tactical Flashlight Review

Wurkkos TD02 Flashlight Review

The Wurkkos TD02 is a single-emitter tactical flashlight using a TIR. It runs one 18650 (included) and has built-in USB-C charging. It’s also inexpensive!

Official Specs and Features

Here’s a link to the Wurkkos TD02 tactical flashlight product page.


There’s only one version.


With cell (as pictured in this post), the Wurkkos TD02 tactical flashlight runs just under $29. You can buy the Wurkkos TD02 tactical flashlight here.

Short Review

As much as I love flashlighty flashlights, I also love tube lights. The Wurkkos TD02 tactical flashlight fits sort of into that Convoy S2+ space, but has more going on in the tube body. There’s USB-C charging (which works ok) as well as a TIR and reverse clicky. I love the package! It’s also inexpensive, which I like. I might opt for an emitter swap to something warmer and I don’t really care about the tactical aspect of the TD02, but I do like the light! It’s worth mentioning here that the TD02 mimics a head design we’ve seen before in the Weltool T2. This does not seem to be a “design sharing” scenario between Weltool and Wurkkos, so pay attention to that if it’s important to you!

^ 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.

Build Quality and Disassembly

As the Wurkkos TD02 is a tactical flashlight, it’s nice to see dual springs used. These are beefy springs, too.

Size and Comps

Dimension: 122mm (length) x 24.7mm (head diameter)
Weight: 62 ±1 gram (without battery)

If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll also show that (usually in 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.

Also above is 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. I also reviewed that specific edition, the “Oveready BOSS FT Collector Vintage Brass” 35. I love it!

Retention and Carry

A friction-fit pocket clip is used. This is a very simple clip but has some nice design features, too. It’s not reversible, nor is it a two-way clip. So bezel down carry is the only option here.

A lanyard is included. While you could connect this through the pocket clip, the tailcap holes are a much more solid choice.

Power and Runtime

A single lithium-ion cell powers the Wurkkos TD02 tactical flashlight. If you buy the package (for $2 more than just the light), you’ll get this 3000mAh 18650 seen below. It’s a button top and is standard.

The cell goes into the light in the usual orientation: positive end toward the head.

Below are a few runtime tests. I did not observe anywhere near 2000 lumens on Turbo, but the stepdown was reasonably long (around 1 minute before the first stepdown.)

Low voltage protection was observed. The indicator just above the charging port (which you can see in the section below) does indicate cell voltage, too. That’s a nice feature. It’ll indicate for about 5 seconds after the light is turned on, as follows:

Green: ~50-100% power
Red: 20-50% power
Red flashing: <20% power


The Wurkkos TD02 tactical flashlight offers USB-C charging and the charging port is in the head. The press-in cover fits securely.

Wurkkos also includes a USB to USB-C cable.

Charging is not particularly quick, at around 4 hours. I think the indicator turns green LONG before 4.25 hours though, and the cell is probably essentially charged as soon as the indicator turns green.

I did not observe this in the manual until testing was complete, but the tail switch has an important role in charging. All my testing was done with the tail switch in the off position. But if you have the switch in the ON position, charging is faster. The manual states it’s 3 hours vs. 2.5 hours. The downside is that the light switches on when charging is complete, in this case.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 2000 2h 1121 (0s)
1044 (30s)
High 1000 2.5h 732 2.10
Medium 400 4h 283 0.74
Low 100 18h 81 0.27
Eco 10 150h 7.7 0.02

Pulse Width Modulation

PWM can be seen on the scope for every mode. This is fast PWM though, and (even) I can’t notice it in person. Nothing to be alarmed about.

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, comparing them to the test light will be easier. 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.

User Interface and Operation

The Wurkkos TD02 tactical flashlight uses a single mechanical clicky. The switch is on the tail and has a nice textured surface. It’s a reverse clicky switch.

LED and Beam

Wurkkos uses a Luminus SST-40 in the TD02. This emitter is coupled with a TIR and provides a nice tight beam.

LED Color Report (CRI and CCT)

My box claims a CCT of 6000K-6500K and that’s about what I observed. The box or manual doesn’t state CRI, but I measured it to be low, at under 70.


These beamshots are always with 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!


What I like

  • Very simple user interface
  • Low cost
  • Great tube design
  • Throw is very near to the claimed throw
  • Build quality is great
  • USB-C Charging

What I don’t like

  • Charging is a bit slow (and maybe questionable)
  • Output does not come close to claim
  • Design features from Weltool T2 appear to be copied without credit
