I'm using a mix of various powered par 38 LEDS. got a deal on 20 of the 36w (12 cree 3w) ones and a bunch of 12x1w blue ones. I also have a bunch of smaller ones to fill in any spaces. No drivers, or pucks... just screw in to a lightsocket and go.
Pac sun has also contacted me about maybe being a demo for the 2011 model, in which case I may go that way. Lots of info but I think its all supposed to be secret though.
