Do you find that you forget to turn on certain lights at dusk or to turn them off during the day? Timers can be helpful in scheduling lights to turn on and off at regular times, but they can be difficult to install and program. For easy installation and control, the Dusk to Dawn Photocell Light Control screws into a lamp base, and its built-in photocell will automatically turn the attached light on at dusk and off at dawn. No additional wiring is required. The Dusk to Dawn Photocell Light Control is for use with candelabra-base bulbs, sold separately. Ideal for compact coach lanterns or post lights, the Dusk to Dawn Photocell Light Control will turn on incandescent candelabra-type bulbs up to 60 watts. The ratcheting base allows the photocell to be aimed toward the light for the best on/off performance. The Dusk to Dawn Photocell Light Control can be used indoors or outdoors in enclosed applications.
