I have a hood with LED's retro fitted into the hood. It wasn't the cleanest mod and the hood I picked up was already cut to accommodate a HOB filter. Still it worked well and seemed to be growing SPS and LPS corals. The blues are on a non dimmable driver and the white and red are dimmable. There are 6 whites,12 blues, 1 red for a total of 19 3W LEDs. The color looked great and best part was it mad it so the tank would run much cooler.
