Ah, okay then. Well any other advice on what I could screw that cfl bulb into that won't be so hot?
they usually are able to simply screw into a normal plastic light fitting.
I know that a few years ago I simply (not suggesting you do this unless you are a trained electrician *disclaimer*) wired up my own lighting socket fixtures and mounted them on some timber and homemade frame.
They were much larger lights then 42 watts, I had 2 105 watt (400 watt equivalent) CFL's one 6400k and one 2700k for a good overall spectrum.
You have to remember that the hottest part of a CFL is the ballast (or plastic bit) not the bulbs so as long as their is sufficient space around the ballast (and good airflow) nothing should get too hot at all.
You have to remember that these CFL's are only drawing the same power as a normal incandescent bulb so they don't need special treatment like an HPS or MH fixture may do
