Abstract
A method of lighting control includes detecting, by a control device, whether an AC power is available, where the availability of the AC power is controlled by a switch. The method further includes providing, by a driver, a driver power to a light source if the driver power was not provided to the light source when the AC power was last available. The driver generates the driver power from the AC power.
