We replaced ceiling fans in an office area of a customer and installed the CFL supplied bulbs. The lighting circuit is controlled only by a wall switch. The lights flicker intermittently and almost strobe, occasionally, for short periods. We purchased 2 other brands of lamps but had the same problem. I am told there may be a copy machine and/or computers on the same circuit or neutral. I'll have to check that. The fans have a remote control for the fan motors but the lamps flicker with or without the fans even being on. Any thoughts or experience with this issue??
If the fan has a remote control, it most likely has a button for the light to dim it, most I have seen you push the button and hold it to dim or brighten the lamp, if you can get a hot up to the remote in the canopy use the existing wire to switch the lamp, and get it off the remote, if the fan has a built in remote, you might have to fish a new wire down the rod through the motor to the light fixture to bring out the lamp hot, or just tell the owner to purchase dimmable CFL's, just remember they will only dim to 40% and go out, but at least they wont strobe which will shorten their life.
Oh and to adjust the lamp button back to full brightness install an incandescent and hold the button with the little lamp image on it, unless you meant that there is a wall control for the fan? if this is the case then make sure you have two switch legs going to the fan and that the light is switched separate?
