Well, I was hoping someone else would help you, but I guess that's gonna happen. So all I can do is give you my best guess that you need to raise your lights. those 1000w fixtures get pretty damn hot- so they should probably be at least 2 feet from the tops, maybe even 3 feet...

I betcha people would be more inclined to help out if you gave em some more info though:
