SunnyD, this project is along the lines of an early commercial product. I am not going to get too technical because that would reveal my electronic design, which is not complete.

I do need to change one thing tho, the R:B ratio. I was hoping that the LED driver I selected would be able to drive enough current to run 5 RED, but that pushes things a bit too far. So I am going to drop it back to 4 RED Luxeon IIIs.

This thread will be a diary of my experience as I work through some of the many design problems. Currently I am at the circuit design phase. Although I do not want to reveal too much of my design at this point I will provide some information that has guided my decisions. The LEDs I will be using are from Lumiled. I am using the Luxeon K2s for the blue spectrum, and Luxeon IIIs for the red spectrum. The ratio of RED to BLUE (I will call Rating: 5
