Westek SLC4CG Gray Automatic Photocell Sensor Control
Westek SLC4CG 150W Screw-In Light Controls sense light levels and automatically turn lights on at dusk and off at dawn. Put an end to coming home to a dark house with this light switch that simulates home occupancy and deters intruders. No seasonal adjustments are required (as is the case with timers). Plus, since lights are on when needed, light controls help save money and energy too.
