Are you going to put lenses on the Cree LEDs? Lenses greatly increase the intensity of the light unless the light fixture is sitting right on top of the tank. I haven't been keeping up on the latest Cree LEDs so I can't say how many of which ones you should use. When I started making LED lights I started by studying LEDs and how they work, plus how they should be powered. Only after I learned all I could did I try to make a light fixture. My first step was to test a single LED using a PAR meter to get data on how much light one would produce vs. distance. It was a very interesting DIY project, and also very rewarding at that time.
