One of, if not the, hottest light Wurkkos has ever released was the little TS10, a 14500 triple with aux lights and Anduril. Now it has a right-angle counterpart in the HD10! While it builds on the original TS10, the HD10 isn’t just a TS10 turned sideways. Since I like the TS10 quite a bit, my hopes are high for the HD10! Let’s see what it’s made of!

What’s in the package

For being a budget brand, Wurkkos’ packaging is very nice. The HD10 comes in a sturdy, plain white box with a flap that has a magnetic closure, and slipped into a paperboard sleeve with branding, imagery, and details of the light on it. Inside, you’ll find the light nestled securely in a firm foam cutout along with the accessories. It’s good packaging that not only looks nice, but it also protects the light!

The contents of the box include:

• Wurkkos HD10 with Wurkkos 14500 inside
• USB-A to USB-C cable
• Lanyard
• Spare o-rings
• Instructions

Like the TS10 before it, Wurkkos offers the HD10 in a few different colors of anodized aluminum. Currently there’s a black light with a silver clip, an orange light with a black clip, and a white MAO light also with the silver clip, any of which can be had with 4000K or 6000K emitters.

If you’re not familiar with MAO (micro arc oxidation), it’s a different process for anodization. It looks nice, but scratches very easily. Eventually the TS10 came in brass, copper, and titanium, so maybe we’ll see HD10 models in those metals as well!

The HD10 takes design inspiration from the TS10, but the body is entirely new. The biggest change is at the head. Obviously the emitters are at a 90-degree angle to the body, but this is also where the button and USB-C charging port are. This makes the head larger and therefore the HD10 is taller than the TS10 overall.

The charging port is directly opposite the emitters and sealed with a rubber cover which seems to be somewhat easy to remove. While it’s rated IP68, I wonder how well it keeps out water. There isn’t a lot of space in that cavity, so USB-C cables with larger plugs may not be able to fit.

To either side of the USB-C port are three cuts into the head, creating cooling fins for heat dissipation. On the top is the new button. I believe the entire mechanism is new because it has an indicator light for charging in the middle of it. I feel like this is significantly easier to press than the TS10’s!

It requires less force, and even if you press it crooked it still activates. Finally, there are markings on all four sides of the head; “Wurkkos” is displayed directly under the emitters with regulatory information opposite it, “HD10” is on the right side, and a heat warning and the serial number are on the left. 

Below that, the body of the HD10 has the familiar slender shape of the TS10, but it’s even more narrow due to the lack of the need for an inner tube. There’s a channel for the clip to attach to at one end of the tube and even though the clip is single directional, you can reverse the body tube!

“Up” is having the clip groove at the head end, but if you flip it you get a pretty deep carry from the included clip. The only thing about having it that way is that the little battery visual printed onto the body appears to indicate the incorrect direction for inserting the battery.

Maybe that should’ve been on the tail. Both ends have anodized threads so you can mechanically lock it out with a slight turn of either the head or tail, and o-rings to help with the IP68 rating.

And on the far end, the tail has a slanted ridge design for grip when unscrewing it. Since the button is out of the way, Wurkkos included a magnet in the tail. It’ll hold the light up, but it’s not a particularly strong grip. Bumping it while it’s on a magnetic surface will almost certainly knock it off.

While the magnet is glued in, you can pull the spring out of the tail and maybe try to add another magnet, as there’s extra space between the spring and magnet. There isn’t any text on the tail cap. Since both ends are flat, you can stand the light on either the tail or the head. It’s good to have options!

Inside, you can see that the driver has a riser board for the emitters and USB-C port, since it’s perpendicular to the battery connection point, which is a solid post on this side. Still, it should be able to handle most 14500s, because the spring has a lot of travel. The driver also has three flashing pads, so you can update the Anduril firmware if you want!

You have a lot of options when it comes to using the HD10. As I mentioned before, you can head or tail stand it, or attach it (carefully) to a magnetic surface, to start. While there’s no knurling anywhere on the light it’s a bit slippery to hold with two fingers, but hooking a finger around the slender body or holding it with your entire hand work well.

There’s also the headband! It’s a simple elastic band with a rubber holder for the light. The holder has a hole on the top as if you could add an over-the-head strap, but there isn’t one included as part of this package. Since it’s only a 14500 light, it doesn’t weigh heavily on your head or strain your neck. You do have to take the clip off to use the headband, as one of the rubber straps will slip into that groove for the clip.

The HD10 just barely fits in the coin pocket of my jeans and makes a great secondary light. Sometimes it’s nice having both a flashlight and a headlight (straight and right angle facing). With the clip, magnet, ability to head and tail stand, and headband, it allows for many usage scenarios. 

The HD10 falls under Wurkkos’ standard warranty, summarized here from their website:

• You can return a newly purchased light within 30 days for a refund. 
• If purchased somewhere other than Wurkkos’ website, you will need to go through that reseller.
• After 30 days, Wurkkos will repair the light for free.
• Depending on your location, you may be required to pay for return shipping to Wurkkos.

Like the original TS10, the HD10 has tiny 2323 (2.3mm²) Latticepower CSP (chip-scale package) emitters in 4000K (as tested) or 6000K.

Wurkkos reports the HD10 as having a 29-degree TIR, and it does produce a beam that is wide and pretty even. As with many TIRs, it doesn’t really have a hotspot and softly fades out around the edges. The LatticePower emitters have a much nicer tint in the HD10 than they did in the TS10v2 4000K is a neutral white, and for its CRI, which is very high as you can see in the chart! Overall, it’s a very pleasant beam!

Do note that, as with the original TS10, the TIR is exposed since there is no glass lens to cover it making it susceptible to scratches. The plain aluminum bezel only extends slightly beyond the TIR, so it won’t protect it all the way. The bezel is screw-in, so you could easily remove it if you wanted to swap emitters

Also housed behind the TIR are a set of 6 RGB aux LEDs. If you know anything about Anduril, you’ll know that these are on while the main emitters are off and are largely for decoration, but also function as location and battery level indicators. They’re not focused by the TIR, so you get a kind of flower petal effect if you hold the light up to a surface with the aux lights on.

Flashlight size comparison with its competition:

Group 1: Emisar D4V2, Wurkkos HD10, Convoy S2+

Group 2: Wurkkos TS10, Wurkkos HD10

Additional info on the UI:

• The HD10 came with firmware 0713 2023 07 29, “TS10 RGB AUX”. After completing the review, I flashed it to the latest version, 2024-04-20

The HD10 comes with Wurkkos’ standard 14500 battery, which is rated at 900mAh. Unlike the TS10, the HD10 has built-in USB-C charging, which makes it more approachable and user friendly. Of course, you can still remove the battery for external charging, or swapping on the go, but having integrated charging is a welcome addition!

While charging, the indicator light in the middle of the button will be red, and will turn green when charging is complete. I found charging to top out around 1A, which is a little high for a 900mAh battery, but it does stop at 4.15V, which is better for the battery than pushing all the way to 4.2V. Personally, I’d prefer to use my external charger to charge it at 250mA for longer battery life, but if I was out and about and needed a charge, the onboard charging would do.

Despite 14500 batteries being the same size as AAs, the HD10 is not compatible with them. It would’ve been nice to have the dual-fuel option, especially because right-angle headlights are often used for and/or marketed to outdoor uses like camping, where charging is not readily available. To be fair, though, Wurkkos would’ve had to rework the driver to accommodate the lower voltage of a AA which would’ve raised the price.

A 250mA capacity test using my Vapcell S4+ charger revealed the capacity of the included Wurkkos 14500 battery to be 820mAh, so below the 900mAh spec. This makes the 1A charging rate even less desirable.

Battery level indicator:

In newer versions of Anduril, such as the one the TS10 Max comes with, the aux will display a color corresponding to the voltage for 3 seconds after the light is turned off. This ranges from purple to red in chromatic order of descending voltage. Here’s a rough outline of the voltage ranges for each color:

• Purple – 4.2-4.1V
• Blue – 4.0-3.9V
• Cyan – 3.8-3.7V
• Green – 3.6-3.5V
• Yellow – 3.4-3.3V
• Red – 3.2-3.0V
• (Aux are off below 3.0V)

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.

To obtain these numbers, I used an integrating sphere and Extech SDL400 data logging lux meter. Measurements have been calibrated using a standardized calibration light provided by 1Lumen.

Interesting numbers here. Usually when you have a light with multiple emitter options and they only give one set of specs, it’s for the highest powered ones, for marketing purposes. With that in mind, I expected my 4000K model to be lower than what was quoted. However, that’s not exactly the case.

While turbo only makes 850 lumens at 30 seconds, the HD10 exceeds the specs for levels 7-4, then falls below spec for 3 and below, with level 1 being unreadable by my lux meter. Makes me wonder what the 6000K version does.

Mode	Amps at start	Specified output	Turn on	30 sec.	10 min.
1	2.3mA	0.5 lm	–	–	–
2	8.1mA	3 lm	1 lm	1 lm	1 lm
3	33.8mA	10 lm	9 lm	9 lm	9 lm
4	125mA	30 lm	36 lm	36 lm	36 lm
5	0.35A	75 lm	103 lm	102 lm	101 lm
6	0.87A	220 lm	313 lm	305 lm	130 lm
7	1.80A	520 lm	685 lm	653 lm	130 lm
Turbo	2.36A	1200 lm	901 lm	850 lm	120 lm

*Turn-on and 30 second measurements are done manually, while the 10-minutes readings comes from the runtime graph. This is our standard approach, though some reviewers may choose a different approach.

Ambient temperature during testing:

• 20°C /68°F

Parasitic drain: 5.0 µA, no aux

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.

To obtain these numbers, I used an integrated sphere and Extech SDL400 data logging lux meter. Measurements have been calibrated using a standardized calibration light provided by 1Lumen.

Unfortunately, the HD10 falls short of Wurkkos’ expectations in terms of runtime. None of the modes I measured met their specifications, and the specs were closer to what I have listed here as shut off.

Really, at that point the output was so low that the lux meter couldn’t read it. That extremely low level continued on for several more hours, though it’s not really useful at that point. I wonder how much of the difference in runtime is due to the battery having a lower than advertised capacity.

Mode	Specified runtime	Runtime (ANSI FL1)	Time till shut off*
1	100h	–	–
2	72h	–	–
3	32h	–	–
4	7h 40min	6h 18min	7h 23min
5	3h 12min	2h 15min	3h 33min
6	2h	1h 22min	2h 41min
7	1h 40min	24min	2h 26min
Turbo	1h 30min	1h 22min	2h 39min

*The last column reflects the total runtime until the light turns off. A “+” symbol indicates that the test was stopped at that point, but the light continued to run. This typically occurs with certain drivers, firmware, or battery types.

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.

The numbers for candela were obtained with an Extech SDL400 data logging lux meter at 1, 5, and 15 meters at 30 seconds, then averaged.

Just like with luminous output, the candela is higher than spec for 4 through 7, but lower than spec below that, and for turbo. Don’t expect a lot of throw out of the HD10. It is, after all, a 14500 light with a TIR.

Mode	Specified intensity	Specified beam distance	Candela measured	Meters	Yards
1	3 cd	3 m	–	–	–
2	12 cd	6 m	6 cd	5 m	6 yd
3	40 cd	13 m	37 cd	12 m	13 yd
4	110 cd	21 m	163 cd	25 m	28 yd

Ambient temperature during testing:

• 20°C /68°F

Camera settings and distance: These were taken with a Canon EOS 600D with the following settings: 

• WB 5700K, ISO 1600, Speed 0.5sec, f/4.5, 18mm
• Distance to the other end of the playing field is 100 meters.

Beamshots of the following flashlights compared:

• Wurkkos HD10
• Wurkkos TS10
• Manker E03H III

Please note that the following beamshots are mainly intended to showcase the beam pattern and beam quality, rather than overall performance. These images are typically taken directly after activation, and in different seasons or weather conditions, and therefore do not fully represent its overall performance. In few cases the camera settings are even different and therefore not meant for performance comparisons. For accurate performance metrics, such as output, beam distance, and runtimes, you need to look at the performance section of this review.
