Light collimation with an LED flashlight

By the way, did you went 4S cell arrangement and classic FET @#$% with the BLF GT?

I'm loving the fully regulated 2S boost H2-C setup, the driver also proves quite capable of feeding all the meat an XHP35 requires safely and efficiently (see: Buck and Boost Drivers, Testing, Modding, and Discussion (Pic Heavy)).

Cheers
