Dusk to Dawn Lighting for Outdoor Locations

In outdoor locations that require dusk to dawn lighting, our 8483 north facing photocell is an ideal solution as it provides consistent light detection, whilst avoiding prolonged exposure to potentially damaging direct sunlight and city artificial spill.

Our 8481 ANSI/NEMA photocell and hard-wired variation (8481H) can also be easily fitted to our pole or wall mounting brackets and socket kit.

Our dusk to dawn lighting photocells deliver not only energy savings by accurately automating lighting controls, but they also offer enhanced security for outdoor locations such as street and road lighting and campuses. And our 8481 hard wired photocell can be of particular benefit to areas prone to vandalism.
