I thought about mounting them into a regular reflector, but inside of a 
UV-absorbing tube. I figured I could make the tube into a wind pipe for 
cooling with exhaust out the back of the canopy. Then it seemed like a 
lot of work. I might still do that though. I don't know where to buy 
optically transparent, UV-absorbing 3" or 4" tube though.
