I'm thinking of going to led's on my 48x18x26 100 gallon, I have 6 T-5's on ice cap ballast now growing SPS and LPS. if I do a DIY with cree led's how many, what color, what lenses and how many and what kind of dim able drivers do I need?
I already have a heatsink that is 42"x7" my tank has a canopy so the light will be 6" off the water. I also have a reefkeeper lite 3 controller.
thanks for the imput!
