Does anybody know how to put a fan or fans on a homemade canopy? I have 2 48" light fictures running 40 watt flourescent lights.

You can put a muffin type fan that you can get regularly at radio shack or similar store in.

Being it's DIY, i'm not sure what it looks like, but you can put them so they're situated near/above the ballasts pushing air OUT of the fixture. If the fixture is enclosed, where the lights themselves are in an enclosed space, you can put one on each end, and have one blowing in, and another blowing out.

Be sure that the fan can run on 120V, or pick up some resistors to make household current work with the fans.

Hi,
With just two 40 watt tubes and the ballast necessary
to run them, you can pick up a muffin fan at any nearby
Radio Shack store. They have several sizes hanging on
the shelf in the parts department in the back of the
stores. They come in various sizes ranging from an inch
and a half up to 5 inch ones. You want one that will run
directly off the AC house current (115 vac). If you
purchase one designed to run on 115vac, then you don't
need any resistors, simply connect the two leads from the
fan to the power (115vac) connections going to the input
of the ballast.
Normally, fans are mounted on the ends of the canopy.
You would mount it at one end, drawing air out of the
canopy, and have a hole at the other end for the cool
outside air to be drawn in. Generally, you would mount
a screen of some sort ( old nylon, very thin piece of
sponge (1/8 thick, that you can see light through) or
piece of gauze) that would act as a dust filter to keep
the light, ballast, and fan at the other end, free of
dirt/dust.

I will look into that. I have not built the permanant canopy yet so I am sure I can make something like that work. THANK YOU for the replies.
