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.

no X10 here
