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.

is it a low energy bulb (or normal fluorescent light)? some have a delay on start up – ratchet freak Feb 4 '12 at 19:50
No, regular small fan light bulbs (incandescent) – LLA Feb 5 '12 at 0:34
Is it possibly not a standard hardwired switch? Some fans are controlled by radio remotes, and the receiving electronics could have a delay. If the switches are identical to your other typical light switches, this probably isn't it. – Shimon Rura Feb 5 '12 at 0:59
Another question. Are the switches regular switches or is it something designed for ceiling fans? – lqlarry Feb 5 '12 at 3:47
Sounds like you have lazy electrons. Or possibly a bad switch. – Tester101 Feb 5 '12 at 3:56

This is one of those problems that you just have to work out systematically, don't be swayed by logic.

  • If there is only one bulb change it.
  • Check the wiring at the light and switch - see that the connections are tight.
  • Change the switch.
  • Try wiring a test lamp to the fixture.
  • Call an electrician. You may have serious wiring issues.

+1 for not being swayed by logic -- it causes so many problems! – Chris Phillips Feb 6 '12 at 23:57

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.

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.

It could be a defective light bulb. It is very odd.
