Right now I'm running a generic 175 Watt MH fixture of my 100 gallon reef(48" x 20" x 24") and I'm not too crazy about it. I figured now was as good a time as ever to jump on the LED band wagon. I'm looking at a semi-DIY build from this site: http://www.reefledlights.com. Right now I'm looking at two potential set-ups-
1. 3 Evil Par 38s (20 K) + 36 Cree XP-G R5 LEDs w/80 degree optics (36 cool white) on a 48" heatsink
2. 72 Cree XP-RE Q5 LED's w/80 degree optics (36 cool white and 36 royal blue on a 48" heatsink

I'm not sure if either option will be better than the either or if I might need more lighting in general?
