I just set-up a luxeon LED fixture for a Bio-orb nano reef. These are reeaaaaallly intense. Only 8 LED's and loads of lumens.

People in the reefing world have been using these for a while now. It's truly amazing what you can do with these in terms of space, power, efficiency, and color configurations. With a large amount of colors for options you can pretty much create any Kelvin you want. I can't wait to see more planted tanks with these LED's.
