I just purchased 12 royal blue and 12 cool white 3w cree xr-e LEDs from reefledlighting.com and I just want to tell everybody how awesome these things are!!! I'm not kidding these things are serious when it comes to par levels vs wattage. I/m almost done with my build and I'm definitely gonna post a lot of pictures. I suggest these things to everyone b/c they put out some serious light and really aren't expensive as long as you are willing to DIY, but I think that is half the fun anyway! I think anybody interested in some great lights should check out the website, and no I don't work for them. I just think the owner (Bill) is a great guy with a great product! CHECH IT OUT!
