I recently put CFL bulbs in all my lamps, ceiling fans and light sockets. On the ceiling fans there are dimmers. When the fan lights are turned on at the dimmer and then turned all the way up, one fan light stays dim for about an hour, then will start to flicker and go to its normal brightness and does not flicker anymore. The other ceiling fan light flickers the entire time and also makes a buzzing noise. i had a dimmer on the kitchen light also and it would also flicker whenever the light was on. I replaced the dimmer with a simple off and on switch and this solved the problem. I only have the problem where there are dimmer switches installed. Why are the lights having this problem?
