The delay is very short but noticeable Maybe a second possibly 2 seconds.
No its not being used for an incadescent load. The light bulbs and fixtures are all standard lighting. The dimmer is a lutron from Home Depot. Its happening on more than 1 light I don't think its the dimmer unless the dely is a built in feature of the dimmer.
I'm checking Lutron C.L Dimmer incadescant halogen 120 volt dimmerable cfl/led.
