I use 3 2 bulb shoplights over my 75G.  I avoided using the chains by
cutting a 2x4 into 6" lengths.  Then I flipped the hood upside down and
placed a chunk of wood between the shoplight and the hood at each end of the
light.  Then I drilled holes through the metal of the shoplight(before bulbs
were installed) and put about 6 screws in each side so that the screws ran
through the metal backing of the light, through the 2"4" and into the wood
of the hood.  After 2 or 3 months there have not been any fires yet :-)  By
doing this you allow for about 1.5" of air circulation between the light and
the wood of the hood.  BTW I picked up this trick from the basement at work
where they did the same thing.  Try to keep the screw and wood backing plate
as far from the ballast as possible.
