are any made?

pros/cons?

I think most major manufacturers make some models with glass over the
opening. I don't know if it is tempered or not, but the problem is that the
glass, usually translucent, absorbs to much of the light, so you'd need a
lot of them to light a room. If you wanted it for a closet , they make flat
glass or dropped glass covers on shower-closet lights
