I do believe pop22 uses some of those led bulbs. pretty cheap on e-bay I think. they had the red and blue spectrum. I just picked up a Galaxyhydro 280w ufo for $109 usd that's looking real good so far.just an option. I used cfl's with good results but it always seemed like I needed more light lol. but your HBSS looks like it will give you one hell of a cola so no worrys
