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.
Just got an update from Amazon US…it says it will be here Thurday…YAY
Being budget-minded, instead of purchasing a 3rd 21700 cell, I will use the 18650 I already have.
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:
I got mine also…when u hit Turbo…it creeps up to turbo like the post above…im unsure the lumen measument.
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.
Hmmmm…how do u check the amps?
Another light but you get the idea.
Thanks…but doesnt help me…no offence…but not good at this…lop…i just have mine set at Voltage…
Show a pic of your multimeter and I will tell how to set it and use very short leads.
Im insure how…never uploaded photo on here. Keeps asking for URL
Open an account at Imgur and post your pics there and link them
What did you get for IR on the Sofirn supplied battery Zozz?
Do you have a clamp meter?
I need to check but if I remember correct it was around 40 mOhms
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.
Ok thanks…i prob wont do it then.
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.
my c8f 21700 also has a brightness climb, but it does not bother me is a bit like HID
with the sofirn 21700 battery, I measured about 2,900 lumens
I also observed that the maximum power at the top of the ramp is a bit higher than the turbo with a double click
