I have power compact lights too. I built a stand for the light. About an 2" from the glass cover. Can't go any higher because of the canopy. I keep my canopy open to cool the light down a little bit. I have 6-65W now.
I'm thinking that a split photoperiod will help with temp swings. What do you guys think? 4 on 4 off 3on 13 off.
