What causes a delay in a light when I flip the switch? It is a led bulb and it is the second one in a circuit of four. I changed the light and it still does it. I also checked all the wiring to see if it was tight and had a good ground. Whats next?
Sometimes LED lights are controlled by transformers or relays. It may be that when the switch is flipped on the current will have to flow to a transformer that changes the household voltage to DC voltage.
