I use ProSource 180W Illuminators, 6 of them, over a 6x4 area (over 1000W's of LED).
I also have 4 CFL bulbs that I use for supplemental lighting, 2x55W and 2x42W (about 200W of CFL).
My LED's don't have any UV or white light in their spectrum, so I make up for it with the CFL's.
The CFL light helps my plants bulk up an extra 10-20% and finish earlier then with the just the LED light alone.
Here's a video about my LED's:
