Well, I purchased my lights from Steve's LEDs. I'm getting 28 2700K warm white, 14 cool white, and 14 royal blue Luxon ES 3W LEDs with 40 degree optics to go on three 60" heat sinks. I hope I have the color ratios right. I will build a new 12" tall canopy to house these about 30" off of the substrate. Maybe I'll get my wife to take some tank shots with her macro and start a journal thread to document the transition to high tech.
