This was made by one of the machinists on here, can't remember exactly who. It will fit a Solarforce host, NOT a Surefire. The top opening was cut to fit a TIR optic, which I do not have. I found it fit a Mcr-19XR rather well, and I am including that in the sale. The Reflector has been modified for a better fit. This heatsink is threaded at the base for attaching the LED to the bottom with tiny screws.
This is a professionally modded 2.8A SB driver. It has 8 additional chips. This means it is a 5.6A driver now'
Aleph can and H/O GDuP driver.
Brand new parts that I ended up not using. Drive levels are 20mA, 180mA, 1200mA. Build your own Aleph LE!
