Thanks Racerx,
Good info. Heat buildup and ventilation would have been my next question being that the room is pretty much sealed. It's hidden so well that my brother couldnt find how to get into it even though he knew it was there somewhere. Right now all I have in there is a phototron. (Ok everyone, stop laughing) It has served me well for over 10 years and saved me lots of money.
So now I'll start looking at air cooled 1000 watts and work on the ventilation system.
Thanks again. Love this forum
