I opened this Spiderfire small cr123 flashlight (from FT) for a mod, and found this rather sophisticated driver

LOL - that's high-tech!
the rest of the host looks alright. looks like it can be a good candidate for a mod

As a host it is quite nice but a bit short, I want a less shallow reflector in it and I have to shave some off the front end of the reflector to make everything fit. But I like the spider logo

There are no components on that PCB? On the other side?

Oh, wow.. I guess this driver already proves wrong the thread I just posted
Haha.. Alright, I'm not really sure it's the world's most advanced, but It's pretty awesome.. And yes, it will be available for purchase to people in the BLF community..
So, what is it?
17MM Diameter (Technically, 16.8MM +/- 0.1MM)
8*7135 (380mA each) 3.04A Driver
Each AMC7135 Individually addressable (means 8 Steps of Brightness with ZERO PWM)
Optional PWMing of one chip gives 1023 levels of brightness in between EACH of the 8 Steps above
When in use, PWM Frequency is 7.8Khz
FULLY Programma…
This thing is amazing. How can they even put it inside such an inexpensive light?!?

. the light works fine though, even on a 16340 IMR.
