I have interfit lights that have been sitting on top of my wardrobe since 2005 and wish I knew then what I know now. I won't ever get rid of them because I like them, there's just no room for me to use them here and they get sooooo hot!
If you must have lights and it's for occasional use why not go for something like this?

just use a window or an open door
