MH reflector

[got bait?]

I am going be be retrofitting my already existing [acronym:385091200d="Compact Flourescent"]CF[/acronym:385091200d] lights with two [acronym:385091200d="Metal halide light"]MH[/acronym:385091200d]. I would like to get a reflector for two [acronym:385091200d="Metal halide light"]MH[/acronym:385091200d] in middle and two [acronym:385091200d="Compact Flourescent"]CF[/acronym:385091200d] on the outsides. Like two 96W Actinics and two 250W [acronym:385091200d="Metal halide light"]MH[/acronym:385091200d]. My tank has a canopy, can I just screw the reflector right into the canopy or will it get too hot? I have the already existing [acronym:385091200d="Compact Flourescent"]CF[/acronym:385091200d] fixture I can retrofit if need be. Canopy has two 4 in fan holes, I'm getting the fans, in top.
The picture enclosed is of tank, currently [acronym:385091200d="Freshwater"]FW[/acronym:385091200d].

It will more than likely be OK, but I would leave atleast an inch of space between the reflector and the top of the canopy. You may find the canopy is too short. It ti recommended that [acronym:dca388c8a7="Metal halide light"]MH[/acronym:dca388c8a7] bulbs are kept 8-12" from the surface of the water.

Is this because of heating up the water too much, melting the acrylic (100gal bowfront W/brace in middle), or just too close to the water in case the bulbs get wet and shatter.
My canopy is currently 8" avove the water, but after I add the reflector and sockets it will be less. I can put the canopy of some sort of raisers if need be. Just wont be astheticaly pleasing. But " Gotta Do what ya Gotta Do" I guess.

All of the above.
