Probly the worlds most common flashlight driver. The 7135 chip based boars are in millions of flashlights world wide. In this video I
show you how easy it is to boost the driver current and gain output from you LED.

If you have any tips and tricks of your own please let us know 
I leave the center pin on and don’t solder the back ground tab but I can see how your method makes it easier to solder without bridging across the pins. I always check for continuity after and sometimes have to touch the pins up a bit.
Nice video, thanks for posting it.
good video, thanks for sharing.
Good old stacking chips! 
(pic from a guy called Andi in 2011)
Edit: tip/trick. In case you need to fit a 7135 chip under a retaining ring: you can file a surprising big chunk out of the corners of these chips without affecting the workings.
Good lux to you too, VOB!
That is a perfect picture of the “ism” part of flashaholism at its best! LOVE IT!!
“Good old stacking chips!”……
I call those condo drivers.
lol that much stacking dows not really bring an advantage as the thermal limitation with like 12 Chips is already getting a problem
But it sure does look awesome :student:
nice video you made.
Hahaha leaning tower of 7135’s I’d say. Nice tip by the way as I usually add mine on the bottom side just because there is more room to work with. Up to now I’ve soldered the driver to the pill in smaller lights.
I’ll have to give that a try. Cheers 
Did my first ever multi triple stack. I don’t change the tip on my soldering iron anymore, just use the large chisel tip for everything lol. Ground connection on 9 and 11 o’clock 3rd tier chips made on the back tab only.
Convoy driver modified for a single 7135 moonlight (9x on the main channel) running BLF-A6 FW, all components on top of board for use with non-filed retaining ring.
Nice work Ck.
