Metal Halides and Wooden Canopy

Hey all, I just got my metal halides in yesterday and mounted them in my wooden canopy. It is a dual 250w ballast, but I am running 175 watt bulbs right now. It looks a lot better.....but the wood on my canopy is warping when it heats up. Is there some type of spacer or flame resistant material that I can use to put in between the reflectors and the canopy to keep it from warping and/or catching on fire?

not sure about fire retardant material, but you could make wood spacers to mount between the reflector and bottom of canopy. i would make the spacers at least one inch or more. then of course the next thing to make sure is that you have about 4-6 inches from water line to bottom of bulb.
here is how mine are mounted, piece of aluminum angle mounted to canopy via a corner bracket
