Here are some some photos along with my comments. Here is the link to the imgur album. https://imgur.com/a/RhXzcb8
Fig1. Size comparison. About same height as Emisar D1.
Fig2. AUX light is bright! It can be configured to display voltage. The voltage is displayed in very fine detail by small changes in color.
To change the AUX mode, you have to click 7 times quickly. If you do not click fast enough, it does not register. Rainbow is the default mode and 7 quick clicks will change the mode in the following way: Rainbow > Voltage > Red > Green > Blue > Off > Rainbow.

Fig4. Tail design in Emisar D1 vs Wurkkos TS25
Fig5. Button in TS25 is protruding. Prone to accidental activation.
Fig6. The button is made of metal. My button was defective. I tried to disassemble it by trying to pull out the switch, but failed.
Fig7. I would recommend making a cut on the head that is similar to that of M21C-U. This prevents rolls. Also makes it easier to unscrew the head for mechanical lock out.
Fig8. A cut in Emisar D1 is also nice. Notice how the button on D1 is recessed. This prevents accidental activation.
Fig9. Emisar D4v2 button for reference. The button sticks out a little bit. This is also prone to accidental activation, but the button on TS25 sticks out more.

The following is the revised version of the my previous review. https://budgetlightforum.com/t/-/71042/139 My button was defective. I contacted Wurkkos via Aliexpress and I was offered a gift on my next order. I didn’t like the resolution and filed a dispute. Aliexpress issued a full refund. I didn’t like the process.
Some issues I found in the TS25 prototype.
1. AUX LED is very bright and consumes a lot of current.
Parasitic drain is measured up to 24mA (lowest measured was 8mA) depending on color displayed.
Here are d_t_a’s measurements:
Color-cycling: 9-26mA (ie. when 2 aux-LEDs are lit-up, then it uses more power, when all 3 RGB aux-LEDs are cycled, it’s at max 26mA)
Red: 12.5mA, Green: 10mA, Blue: 9mA, Off: 0.06-0.11mA (60-110uA)
2. AUX LED setting is not standard
Standard setting methods do not work. 7H and 7C from OFF at Advanced mode does not change the output level or the mode (or color). You have to click 7 times (7C) quickly for it to change the AUX LED mode. If you click slowly (as you can in standard Anduril UI lights), it will not do anything.
3. Users cannot easily update firmware.
There is no access to flashing pads. So, I guess it would be very hard for an ordinary user to update firmware even with the right tools. I don’t know if USB-C can be used to update the firmware. It would be nice if it is possible, but there has not been any discussion of the feature.
4. Battery level check blinks are weird.
When I click 3 times when off, the light blinks two number representing battery voltage. For example, 4 blinks pause 1 blink means 4.1V. However, AUX light is turned on between the blinks. This makes it confusing to count the number of blinks.
5. Button is protruding and is prone to accidental activation
It seems that the the button can be depressed easily by accident. Since the light can produce very high output, this can be dangerous if activated in pockets or bags. There are numerous cases where high-output lights burn holes on dark colored synthetic fabrics. The button is protruding from a flat surface, therefore a bump on the wall could activate the switch. I usually mechanically lock-out my lights, so this is of less concern for me, but others may be worried.
Things I liked about TS25.
1. Nichia 519A 5000K is very nice. Very neutral. Nice tint.
2. AUX voltage color changes gradually
Standard Anduril 2 lights displays 6 colors (purple, blue, cyan, green, orange, red), but TS25 changes the colors gradually. For example, cyan color would show more green as the voltage drops in TS25. In KR4 on the other hand, will show cyan and then green as voltage drops. In other words, voltage display via AUX LED is continuous in TS25, but is discrete in other Anduril 2 lights with AUX LED.
3. Very bright. My home-made lumen meter measured 4000lm. (using fully charged 40T)
4. Reverse charging feature is nice. I was able to charge my phone at 2A using the light. You need USB-C to USB-C cable to do this.
5. Charging speed is very fast. My charger was able to push 2.4A (which is max current for my charger). However, finished cell has slightly high terminal voltage. When taken out after charge, the voltage was at 4.22V. I think lowering terminal voltage would be safe for this type of charger.
This trial production is half baked and incomplete. I expected more refined version for the money I paid. AUX LED consumes too much current and its configuration is not standard Anduril. Also, you cannot lower the brightness of the AUX led without completely turning it off. I think Wurkkos should have asked far less for this pre-production unit. Also, I hope Wurkkos would disclose clearly how incomplete the trial production can be.
I recently ordered and received the production model. Here are some of my observations.
aux off: 0.07~0.10mA
aux low: ~0.46mA
aux high: ~12.17mA (Purple 10.42mA, Blue 4.18mA, Cyan 6.27mA, Green 2.55mA, Yellow 9.20mA, Red 7.20mA)
The power consumption on high aux is halved compared to the pre-production unit. However, the RGB aux is still very bright. TS25 on high aux measured about three times brighter than D4V2 on high. (TS25 blue on high 835lux vs. D4V2 blue on high 265lux)
The aux on low is very dim and very hard to notice. You can notice the aux led light if you see the TIR from the side, but if you look at the light from the front they are almost impossible to notice even in the dark.
The button led does not turn on when you turn on the light. In my pre-production model, the button led turned green or red depending on battery level, but it does not do that any more in the production unit. It only turns on when being charged or acting as a power bank.
The power bank quality is decent. The output is fairly well regulated. I don’t see high voltage ripple that you can see on cheaply made power banks.
TS25 power bank can supply 3A at 5V. You have to use quality cables to achieve this output. When USB-C cables are plugged in, it correctly detects the attached device and supplies power.
Peak to peak voltage difference is measured around 60mV. On top of the notch power banks I own, the numbers are kept as low as 30mV. My Samsung OEM 25W USB-C adapter was measured 100mV and 10W USB adapter was measured 30mV. So, I would say TS25 power bank is on par with OEM power adapter.
I am not knowledgeable enough to comment on safety features of the TS25’s power bank feature. I am a little reluctant to use a power bank if it is not made by reputable brand as I had a catastrophic experience with bad power banks. But so far, it passes the output stability test for me.
