totally happy with my LEDs
I switched from 250 MH over my 50 gallon to 36 Cree XP LED's DIY. Totally happy with the looks of it, the dimmability and the flexibility of color combos. It grows my corals like nothing else and is upgradeable if I want. The only thing is that the colors of some of my corals changed when I went from MH to LED. Some for the better, some for the (in my eyes) worse. And when you turn those LED's on, you have to turn them way down because if you don't they'll burn some of your corals. Also, I love the fact that I no longer need to worry about heat and have my controller turning my MH on and off all day due to over-heating. Overall, I'm very happy - my tank has never looked better.
