^ 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

Size and Comps

Dimension: 152mm (length) x 59mm (head diameter)
Weight: 200± 1gram(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 lanyard is included for carrying the Wurkkos TD01 tactical flashlight.

I like the tailcap holes – one side has just one hole but the other has two. This offers choices!

Power and Runtime

The Wurkkos TD01 tactical flashlight is powered by a single 21700 lithium-ion cell. If you buy the kit (which you should), you’ll get this 5000mAh seen below.

This is a standard 21700 cell. With the internal setup of the TD01, any 21700 should work fine. The cell is installed in the normal direction – positive terminal toward the head.

Below you can see a few runtimes. I was impressed by the output… Except that the light claims 2200 lumens, and even at startup I’m only seeing around 1400 lumens.

The light does have low voltage protection.

Charging

The Wurkkos TD01 tactical flashlight has built-in USB-C charging. This charging port is opposite to the switch and fairly easy to notice by feel – the charge port cover is grippy, while the switch is stubbly (knurled).

I am very pleased with this charging port cover – it sits very securely, but is also easy to open when needed.

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

Modes and Currents

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens	Tailcap Amps
Turbo	2200	2.5h	1387 (0s) 1279 (30s)	7.60
High	900	4h	546	2.03
Medium	350	9h	188	0.68
Low	150	15h	89	0.42
Eco	30	70h	20	0.10

Pulse Width Modulation

There is PWM on all modes except Turbo. On all but the lowest output level, it’s not PWM that I can call “noticeable.” It’s plenty fast PWM.

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 Wurkkos TD01 tactical flashlight uses two switches. First, and most important, is the mechanical tail switch.

The switch is not proud, but accessible from two sides, even if you’re wearing gloves. It does stick past the metal part and does prevent tailstanding.

This mechanical switch controls only on/off. Next is the e-switch on the head, which controls the modes. The switch is just a little proud and has a hard cover with an indicator right in the center.

The action is low, and not incredibly quiet. It’s also an indicating switch!

Here’s a user interface table!

State	Action	Result
Off	Click Tail Switch	On (Mode Memory, excluding Moon)
On	Click Tail Switch	Off
On	Click Side Switch	In Group 1: Mode advance (Eco, Low, Med, High) In Group 2: Mode advance (Med, Turbo)
On	Hold Side Switch	Iterate between Group 1 and Group 2 (If entering group 1, flashes 2x in Moonlight. If entering group 2, flashes 2x in Turbo.)
Off	Tap Tail Switch	In Group 1: Momentary (Mode Memory) In Group2: Turbo
On	Double Click	Turbo
Turbo	Click	Return to the previous output level
On	Triple Click	Strobe
Strobe	Double Click	Strobe advance (Strobe> SOS> Beacon)
Off	Hold Side Switch, Click Tail Switch	Moonlight (notably this means moonlight is also available in the Tactical group, which is nice!)

LED and Beam

Wurkkos has used a Luminus SFT-40 at “6000-6500K” in the TD01 tactical flashlight.

LED Color Report (CRI and CCT)

The light is very cool white, ranging from around 7000K to around 7600K. This is very cool white. But it’s no surprise, and what you’d sort of expect from a high-output, high-throw tactical light.

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

• Good build quality
• Great throw
• Two groups with a fairly sensible tactical group
• Moonlight still available in tactical
• Moonlight is accessible directly from off

What I don’t like

• Doesn’t hit the output specification
• Only a lanyard is included for carry
• user interface is not complicated with a ramping group
