			 since i started I've been using a 3mm sheet of glass to block out the excess UV from my two hqi's, but now with a 1x400 mogul, I don't really need a sheet of glass any more do I? I've never had heat problems with a sheet of glass, but with a 400 watt would it cause the temperature to skyrocket?
