Visual styling is often a key to any item’s appeal and desire to own or use it. The TD02 from Wurkkos hits the mark in this department very well. It looks extremely cool and purposeful. The specification sheet seems good too for the price.
Wurkkos seem to be heavily marketing the TD02 as a “tactical flashlight”. But I think this might be simply down to the matt black finish. As I’m not seeing any tactical design elements that would make this light useful or a go to light in any would be tactical situation.
The TD02 comes in a nice Wurkkos branded box and is well packed with the LED specs clearly labeled at one end of the box. No assembly is required, all you need to do is remove the little disc isolating the battery and maybe fully charge it up. It comes with the pocket clip pre-installed. In the box you get:
- Wurkkos TD02
- Pocket clip (installed)
- 2 x spare o-rings
- USB-C cable
- Wurkkos branded 18650 battery
- Lanyard wrist strap
Flashlight in use
Wurkkos claim the TD02 has tactical qualities, however unless you plan to throw the torch at a would be assailant, I can see no tactical aspects to its design or features. It is however a good size for a general purpose EDC light. I actually really like the look and design of the body and head. It feels good in the hand too and is nice to hold.
With so many 21700 lights hitting the market currently, you forget just how compact and small an 18650 light is by comparison. The TD02 is for me the ideal carry size and weight. Knowing that it should offer a great mix of performance vs runtime. 21700 lights are often too bulky in the pocket and quite heavy too. While 14500 lights tend to lack runtime by a huge amount. The 18650 is the “sweet spot” for this metric.
The body is very grippy, yet smooth with no sharp edges. The TD02 will also happily headstand, although lacking any crenellations means you may not know if you have left it on or not. It will tailstand too, although when off the rubber switch slightly protrudes making it very wobbly, when activated it stands better, but has two large recesses around the button, giving only a small area for it to stand on. Making it prone to falling over at the slightest movement.
The tailcap also has a lanyard attachment point and houses the reverse clicky switch. It is refreshing to get a proper mechanical switch rather than an electronic one. I wish more lights would offer clicky switches these days. The switch feels “ok”, but took a little bedding in with the rubber boot making a weird popping sound of trapped air for the first day or two.
The pocket clip is quite good, although I’d personally prefer it to be a deep carry design, it also only has a small surface area making it bite and grip only mildly to some materials. The body is fully reversible should you want the clip facing the other way. And threads at both ends of the body are anodised and silky smooth. Offering an additional physical lockout should you want it. The pocket clip also serves as an anti-roll device.
The TD02 offers USB-C charging, making it handy as a light on the ‘go’ or if you are traveling. This has a nice rubber cover that fits well and is easy to open.
All in all the TD02 is a solid performer in many ways, only let down with the LED tint and User Interface.
Build Quality and Warranty
The Wurkkos TD02 looks and feels really good, very much a premium feeling light in terms of finish, machining and fit. There isn’t a sharp edge on the light, despite the aggressive grip pattern on the body.
The TD02 is made from a chunky feeling aluminium but somehow feels light in the hand. I especially like the finish in a matt black anodising.
The Wurkkos website claims it has a mineral glass lens, but this does not seem to be the case. There is no separate lens on this model as it uses a TIR optic. The bezel does unscrew, although signs that there might have been some kind of locktight on the threads. But there was no resistance in removing it. This gives easy access to the LED star, if maybe a little fiddly to get a soldering iron into the recess.
The main driver board looks to be glued into position.
LED, Lens, Bezel, Beam, and Reflector
The TD02 uses the SST-40 LED. It is claimed at 6000-6500k and my Opple light meter confirms this Kelvin rating.
- x = 0.3193
- y = 0.3396
- u = 0.1984
- v = 0.3165
- CCT: 6108K
Which is a shame as the LED tint is certainly one of the poorer aspects of the light. It feels very cold and doesn’t make outside colours look very nice overall. It certainly isn’t the worst tint I’ve seen, but in 2023 for a brand and build quality such as this, it does make it feel like a 10-15 year light in terms of tint. Thankfully the bezel can be unscrewed, the TIR dropped out and you should be able to desolder the LED and replace it with one of a nicer tint and/or CRI.
On the flip side, I really like the beam profile. It uses a nice TIR optic. The beam looks a little ringy if you are white wall hunting. But in normal use the beam works well. TIR optics offer quite different beams to regular reflector lights, giving a large hot spot that occupies most of the beam. But it still has decent throw for its size.
As mentioned earlier, the bezel is completely smooth. Not really an issue, but a few crenellations are usually good to have, as you can see if you have left the light on should you place it head down.

Wurkkos TD02 UI: User Interface and Driver
- Eco, Low, Medium, High, Turbo
Available blinky modes:
- 1 click: On (last mode memory)
- 1 click: Off
- half click: scroll output modes Eco – Low – Medium – High – Turbo
- quick double tap: strobe
- Sad to report that there is and it cannot be turned off.
- There are no shortcuts.
Low voltage warning/protection:
- Charging light shows battery status when light is activated.
- Strobe only
- Physical via clicky or undoing the tailcap
- None that I can detect.
Additional/summary info on the UI:
- While the LED tint is a major downer with the TD02, it is solvable. The real issue is the User Interface. It has two major flaws with it.
Firstly it has mode memory. Now while some may like this feature, it just doesn’t work when you have five output modes and no short cuts. This lack of foresight makes the light pretty much useless as an EDC light or for any vane attempt at offering a tactical light. For the simple reason that you have absolutely no idea what mode the light will activate in. For example, if you want to preserve your night vision and maybe use the light to navigate to the bathroom late at night. You might find yourself turning the light on in Turbo mode.
Conversely, if the last mode you used was Eco and you want Turbo, you are then forced to slowly scroll through all the modes to get to Turbo. If you click too quickly you’ll activate strobe, which is just annoying. If you could enable or disable mode memory it would earn the TD02 at least one more star on the overall rating and make it a light I’d consider actually using. As it is, the light, despite the beam profile and physical design. Is just far too annoying to actually want to use it.
Secondly, Not having a quick way to Turbo. As highlighted above, I couldn’t keep a light like this by the bed. Too much risk of the wrong mode being the one it turns on with. But likewise, it is just too annoying to use outside, as you seem to spend your entire time scrolling through the output modes. If it had say 3 outputs modes it wouldn’t be so bad. But 5 modes to continually scroll through and usually activate strobe far too often and far too easily gets very tiresome quickly. In fact a light like this doesn’t need mode memory. Just default to always turn on in Eco and allow the quick double tap to activate Turbo. That way you could get to either end of the output spectrum quickly and easily.
For me, such poor User Interface design can not be condemned enought and on the basis that all lights are intended to be used. I could not recommend any light with such a poor user interface to anybody.
The main driver board appears to be glued in place too, so no quick fixes for the modding community either.
Wurkkos TD02 Charging and batteries
Wurkkos do supply a claimed 3000mAh 18650 battery in their own shrinkwrap. I’m unsure on any other specs for the battery or its exact chemistry. A standard USB-C cable is supplied, the TD02 comes equipped with a USB-C charging port with a rubber cover.
There is also a battery/charge indicator light that shows either green, red or flashing red. The light is easy to charge and doesn’t seem to take too long either. Using a 3.1amp USB port the TD02 would get quite warm when charging and reduce overall charging times.
There is a spring on the driver board, so while the light comes supplied with a button top 18650, it should also work with a flat top cell.
Lumen measurementsHow 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.
To test output and runtime I use a homemade integrated sphere with a light meter and timer. As well as a secondary lightbox and the Ceilingbounce app for Android. Testing is conducted to ANSI FL1 standards to the best of my ability.
Performance for the TD02 overall seems ok. As I’ve said, the tint isn’t great, but the beam and general output of the TD02 are very good. Although it seemed a little low on High and Turbo modes when recording the numbers. I have another SST-40 light under test at the moment that claims very similar outputs and you can physically see the TD02 is not as bright, despite both claiming the same turbo lumens.
|Mode||Amps at start||Specs||Lumens @turn on||Lumens @30 sec||Lumens @10 minutes|
|Eco||0.03||10||9 lm||9 lm||9 lm|
|Low||0.29||100||90 lm||90 lm||? lm|
|Med||0.80||400||303 lm||296 lm||283 lm|
|High||1.98||1000||743 lm||734 lm||401 lm|
|Turbo||3.38||2000||1279 lm||1222 lm||393 lm|
- None due to physical clicky switch
Wurkkos TD02 Battery Life: Runtime graphsHow 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.
My ANSI FL1 runtime tests don’t correlate very well with the claimed numbers. I also find it disappointing that most lights these days do not offer any sort of flat regulated output. I understand big hitting Turbo modes may well be direct drive or running at high amps with a ramping profile to the output. But on a Medium mode it feels a step backwards from a decade ago when lights would regularly offer nice flat stable outputs.
|Mode||Specified runtime||Measured runtime ANSI||Time till shut off|
|Eco||150h||Not tested||Not tested|
|Low||18h||Not tested||Not tested|
|Med||4h||6h 33min||7h 15min|
|High||2.5h||3h 18min||3h 19min|
|Turbo||2h||3h 3min||3h 58min|
Wurkkos TD02 peak beam intensity and beam distance measurementsAbout 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.
|Eco||17m / 71cd||96cd||20m||22yd|

Note: While our star rating provides a reliable indicator, we encourage you to read the full review to make an informed decision based on your own needs and preferences.
The Wurkkos TD02 promises much and I love how it looks and feels in the hand. And the on paper performance also sounds good. Reality is however hugely tainted by an appalling user interface that will annoy the hell out of you to the point that you simply won’t bother using the light any longer. The poor LED tint is also a bummer, but one that can be easily remedied if you fancy some simple modding.
Honestly, if the UI had been halfway decent I’d have given the TD02 4.5 or maybe even 5 stars. But it is so hateful to use as an EDC light, that it relegates it all the way down to a 2.5 star rating.
