Abstract
An improved lighting control for a luminaire operates an LED luminaire so that its relay opens and closes at or very near the zero current cross-over point so as to reduce the in-rush current to the luminaire, and, if the relay contacts do become stuck, the photo control senses the sticking and electronically vibrates the relay to free its contacts.
