I built an Anduril driver with an ATTiny85 MCU and FET+1 set up, used a 17mm driver board from Wight, the A17Hybrid-S, and adapted it up to the 21mm opening.
Yep, I’m glad I found this, I thought WTF is going on? :person_facepalming: The driver is a POS! The lumin output in all modes creeps up and the higher modes even more slowly, as do the amp readings. Took forever to get the highest amp/lumin readings? Best I got was 2440lm. at Turbo and 6.43amps, using a 30T with an 8awg jumper wire, not the cap. With the cap it was like 2100-2200lm. :cry:
But I bought it to tear it apart… so meh…Truly love the build quality, it is outstanding! :+1:
Mine with the stock Sofirn battery made 3100 lumens. I also noticed that it is creeping up. And mine draws 8,5A
I ope Sofirn take a look at the drivers. I told them there are some issues.
turn the switch to the 10A position. 180° from this. And plug the red wire to the empty hole next to 10A position. Put the red probe to tube edge and the black to battery and then turn the flashlight into turbo and read the numbers.
BTW with long wires you will reading low numbers because at over 4-5A the wires act as a resistance in the circuit. So the best way to measure high power flashlights is a clamp meter.
I replaced the original MCPCB of my C8F 21700, with one I had purchased a few months ago from Sofirn on which I put 3x XP-L2 (UU640H) ,
Now I get almost 3300 lumens(@CRI90) , and almost 13A at the tailcap.
