Strange Buzz and Flicker with Compact Fluorescent Bulbs
I have ceiling light that takes 3 bulbs. If I replace all three bulbs with cf light bulbs the light switch will make a buzz sound when I turn on the light. It does this in three different rooms that have the same built in light fixture. If I
replace just one of the three cf's with a regular light bulb, then the buzz in the light switch stops. Also, in one case if I had 3 cf's I would get flickering, and when I replaced one with a regular light bulb the flickering went away. Anyone know why this phenomina occurs?

It is becasue your switch is probably a dimmer or otherwise triac controlled, and set up for incandescent loads.
