BOYZNUS Reviewed by BOYZNUS on . Lumens CFL/HPS I've always used single or multiples of 400watt HPS lights for a 3'X3' canopy,this gives me around 5555 lumens sf... my question is whats the differents between the 400W giving 5555 and say a 85W CFL giving 5500 over the same sf? besides needing 9CFL's to cover the same area..
