Over the last few years I’ve had a number of Wurkkos lights, some just for review, but some I’ve bought myself. On the whole I like what they offer and especially for the price point they are normally pitched at.

The Wurkkos TD01 is available with or without a battery and you can also opt for the TD01C with the constant current driver. In this instance it is the regular TD01 with a Wurkkos branded 21700.

The biggest defining feature of the Wurkkos TD01 is the rather humongous TIR optic. I’ll be honest and say I’m a sucker for almost any light with a TIR optic, so I’m very keen to see how this performs. The TD01 also comes equipped with the SFT-40 LED. An LED known for throw, but one I’ve not been overly keen on, often giving quite a blue’ish tint to the beam. On the whole I normally prefer the Osram W2 for this kind of use. But I’m super excited to see how this Wurkkos light performs!

What’s in the package

The TD01 comes in a nice retail style presentation box with an outer sleeve and a sturdy cardboard box with nice white wrapping and a magnetic closure flap. Inside you get a light in cut foam and  some accessories:

• Wurkkos TD01
• Optional: Wurkkos-branded 5000 mAh 21700 li-ion battery
• USB C charging cable
• Lanyard
• User manual
• Setup card
• 2 o-rings

This is a complete, ready to go kit. You would want to fully charge the battery to get the most runtime and output, since it came at a nice storage voltage. No charger needed either, just plug and go. Remove the insulator under the tailcap though or it won’t charge (or turn on!).

The Wurkkos TD01 is built to be a thrower and nothing else. Although the beam does put enough useful light out that you can use it for a semi-general purpose light. But outdoors for distance is where this is intended to be used.

The build seems comparable to other Wurkkos lights I’ve owned. Mostly fine, but a few details are lacking. In this specific case there must have been an off day in the QC department as they have managed to print the name and model number on the wrong side. It is with the charging port and not the side switch. Overall a minor issue and doesn’t impact usage. However, as I mention in the UI section the side switch feels a bit mushy, at least compared to the side switch on the Wurkkos TS22 I had recently.

The tailswitch is also of concern, it protrudes far too much from the tailcap to be able to tailstand and the switch is incredibly rubbery to use and makes a rattling click when you use it. It doesn’t feel like it fail prematurely, but it is one of the poorer switches I’ve sampled in recent times and has on occasion made mode selection difficult or hasn’t clicked when you expect it to or even an extra click when you didn’t mean too.

While I’ve not been a fan of the the SFT-40 LED in the past, when combined with the TIR optic and out across the fields, I have I’m finding I very much like what the TD01 offers. While the beam is a bit ringy on a white wall, you just don’t notice it to any great extent when using the light properly.

Flashlight size comparison with its competition:

Group 1, top to bottom: Wurkkos TD01, Wurkkos TS22, NightSearcher Magnum 3000

Group 2: Wurrkos TD01, Lumintop AD01, Maglite ML25LT

Group 1 ‘Stepped Mode’ has 5 modes plus Moon, Turbo, and 3 blinkies for more general purpose use. 

Group 2 ‘Tactical Mode’ has fewer modes and rearranged Turbo/Strobe functions for tactical or duty-use. This is something found on higher-end lights like Fenix or Acebeam or Nitecore, so to see it on a Wurkos is nice. Note the TD01’s UI nixes the Moonlight mode. To switch from Stepped Mode to Tactical Mode: From ON press and hold the e-switch for 4 seconds. The light switches to either Turbo mode if switching from Stepped mode to Tactical, or Eco if switching to Stepped Mode.

Available modes in Stepped Mode: 

•  Moonlight, Eco, Low, Medium, High, Turbo

Available modes in Tactical Mode: 

•  Medium, Turbo

Available blinky modes (both mode groups):

• Strobe, S.O.S, Beacon

From OFF in Stepped Mode:

• Single click rear clicky: Turns on in last used brightness
• Tap rear clicky: Momentary on in last used brightness
• Press and hold e-switch while clicking rear switch: Moonlight
• Tap then fully click rear switch: Turbo

From ON in Stepped Mode:

• Single click rear clicky: Turns off
• Single click e-switch: Changes modes E-L-M-H-E
• Double click e-switch: Turbo
• Triple click e-switch: Strobe. To switch between S.O.S and Beacon, double click the e-switch

From OFF in Tactical Mode:

• Single click rear clicky: Turns on in Turbo
• Tap rear clicky: Momentary on in Turbo
• Tap then click rear switch: Strobe. Double click while in Strobe to switch between S.O.S and Beacon

From ON in Tactical Mode:

• Single click rear clicky: Turns off
• Single click e-switch: Switches between Medium and Turbo
• Double click e-switch: Strobe. While in Strobe, double click to switch between S.O.S and Beacon

• Double click e-switch (Stepped Modes): Turbo
• Double click e-switch (Tactical Modes): Strobe
• Tap then click the rear switch from OFF (in Stepped Mode only): Turbo
• Triple click e-switch (in Stepped Mode only): Strobe

Low voltage warning/protection:

• The switch LED indicated battery state when turned on for 5 seconds: 
• Solid green 50% to 100%, 
• solid red 50% to 20%, 
• flashing red less than 20% remaining battery

Strobe/blinkies

• Strobe, S.O.S, Beacon

Lock-out mode: 

• Manual lockout: Unscrew the tailcap 1/8

PWM

• None

Additional/summary info on the UI: 

• On face value the UI seems quite ok, although part of me thinks that it just isn’t making the best use of dual switch setup. For example the Wurkkos TS22 with only a single electronic side switch seems to offer more flexibility than the TD01 does with dual switches. I guess this is a side effect of wanting to make the TD01 more “tacticool”. 
• The sideswitch of the TD01 is also larger than that found on the TS22 although looks the same style. It isn’t bad, but has more play and less precision than the one on the TS22.
• But it is the rear switch that I have most issues with. It is hugely rubbery and imprecise to use. And double clicking it can be a challenge. Sometimes you’ll double click it, but it will only do the single click action. I also have a huge complaint that the rubber boot protrudes slightly from the edges of the cap. Clearly it has been designed to allow tail standing, then they have fitted a switch boot that is a mm or so too long, either on or off, it will not come close to tail standing. I don’t mind lights that can’t tail stand, but if this is the decision, have a completely exposed switch, rather than one that has raised sections around the switch.

The Wurkkos TD01 takes a 21700 size battery,  a Wurkkos-branded 5000 mAh 21700 cell. I don’t know who makes this one, but they have performed well in other Wurkkos lights I’ve used.

This is a flat top unprotected battery. Thanks to the dual springs, the TD01 worked with every 21700 I threw at it bar a super long Cyansky 21700 that has an integrated USB charging port, it was too long to fit.

You get onboard USB C charging, good for 5 volts 3 amps. After the runtimes, the average capacity added was about 4100-4200 mAh in about 3 hours. Ending voltage was a conservative 4.13 volts.

Lumen measurements

How Lumens are Measured: Understanding ANSI FL1 Standards How Lumens are Measured: Understanding ANSI FL1 Standards: The ANSI FL1 standards specify that output in lumens should be measured 30 seconds after turning on, as this is the standardized time for measuring brightness according to the industry standard. This is why we focus on this part in our measurements. The ANSI FL1 standards require an ambient temperature of 22 ± 3°C. We record the ambient the ambient temperature to identify potential reasons for any observed discrepancies.

Mode	Specified	Turn on	30 sec.	10 min.
Eco	30	20 lm	20 lm	–
Low	150	95 lm	85 lm	–
Med	350	203 lm	203 lm	200 lm
High	900	585 lm	581 lm	387 lm
Turbo	2200	1539 lm	1504 lm	558 lm

Ambient temperature during testing:

•  11°C

• None

Wurkkos TD01 Battery Life: Runtime graphs

How Runtimes are Measured: Understanding ANSI FL1 Standards About ANSI FL1 runtime standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

Mode	Specified	Runtime (ANSI FL1)	Time till shut off
Eco	70h	Not tested	Not tested
Low	15h	Not tested	Not tested
Med	9h	8h 27min	8h 52min
High	4h	2h 33min	4h 14min
Turbo	2h 30min	2h 28min	3h 17min

Peak beam intensity and beam distance measurements

About Peak beam intensity: Understanding ANSI FL1 Standards About peak beam intensity The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). This means that the intensity has decreased so much, it becomes difficult to see darker objects, or objects that don’t reflect light. The columns ‘Meters’ and ‘Yards’ use rounded numbers.

Mode	Specified	Candela measured	Meters	Yards
Eco	3550 cd / 119m	3143 cd	112m	122yd
Low	17,100 cd / 261m	12,288 cd	222m	243yd
Medium	32,192 cd / 357m	27,241 cd	330m	361yd
