Good luck with impressing any of this upon anyone here. Ive been inserting this in just about every thread about lighting on this forum for a few years now. Even the part about cannibalizing the little driver board inside the mr16s for your choice of led smd or bulb.
Cue the tumbleweeds and cricket chorus. I dont git it.
