everything...this is a daunting,challenging, and exciting project.How many watts would a cree light require to cover a 4x4 footprint?
I'll have to track down the post, however I think SDS hypothesized that the MAX should be about 55W of actual power draw per square foot of LED light. So hypothetical say one vero 29 or CXA 3070 driven at 1400ma per square foot, 16 in total for about 800W of power draw excluding the driver and fans. However that would probably cause bleaching, so maybe dim them down to 1050ma or even 700ma. Most people seem to be having the best results with the 3kK cree and 4kK Bridgelux chips.
