We have a ceiling fan light. One swith controls the fan, the other the light. When I turn on the light switch, there is a noticable delay (like a full second) before the light comes on. Is it a wiring issue? I notice no blinking, no other problems, just the delay.
This is one of those problems that you just have to work out systematically, don't be swayed by logic.
Also don't rule out the fan. I've installed one fan that had a rather large capacitor on the light circuit. Not sure of the reason of the capacitor but that light had a small delay when turned on.
I had this problem with an dimmer switch designed for use with LED and CF bulbs. I was using incandescent bulbs. I returned the dimmer switch to home depot and got a regular "for incandescent only" dimmer switch and the problem went away.
I had the same issue with a combination switch with a Hunter fan. My delay for the light to come on was several minutes and then sometimes the light would flash like a strobe light. After reading comments from this site I decided to purchase another Hunter fan and see what happens. I connected the fan and light. It now comes on instantly without any delay. I have another fan/light combo in another room. The delay is only a couple of seconds but no other problem. My suggestion is to purchase a new light/fan if you are having the same problems that I was. Not sure if it is safe to keep using it like mine was operating. Apparently there was some regulation about delays that I have read in some other sites.
It could be a defective light bulb. It is very odd.
