Nothing? For one if water splashes on a hot bulb I'm sure it will crack. It has happened to me with other types of bulbs, not CF, but I'm not going to experiment.
Only on raised fixtures I haven't had covers, but this one isn't raised.
Main reason though - I need to add it to maximize the efficiency of the fan cooling. With an open bottom there is a lot of air bypass. If it is closed then air is entering and exiting the fixture through the fans only, and passes fully over the bulbs.
So polycarbonate is ok? I contacted a local supplier and he said it was definately better then acrylic, but was still leary.
