I just put 3 flourescent replacement lights in my bathroom (shaped like a
spiral, meant to replace the incandescent bulb in the same socket).

When I turn on the power there is a very audible hum. I know that
flourescent's can hum but did not think it would be this bad. Is the
humming a possible indactor of another problem? I can't have a bulb that
makes this sound in a small bathroom.

Do you by chance have an X10 wall switch that controls the lights?
I've found that CFL bulbs aren't compatible with regular X10 wall
switches or controllers.
