How would you light up a sps dominant system?

If you ran 6 kessils a360w you would be able to grow anything. You could also hanging them 8" off the water without any light spillage at all. My tank is in our great room and our couch in two feet away from my tank they light up your tank not the room. I think you could get away with five. I run three my tank is 56"L 24"w 26"h. Oh yeah no chiller just saying
