A Photocell allows the user to supply power to a WAC Landscape Lighting power supply during the evening in the absence of UV sunlight. The photocell plugs into the outside of a WAC Landscape Lighting Magnetic Power Supply case, and provides voltage to the unit in the absence of sunlight while blocking voltage during the day. Use a remote photocell (9000-PCR-GY) with wire when the power supply is installed in an area that does not receive any direct sunlight.
