Lighting sensors reduce energy consumption and operating costs by ensuring lights run only when and where they are needed. Occupancy sensors detect motion or body heat to switch lights on automatically when a space is occupied and off after a set delay once the area clears. Photocell controls respond to ambient light levels, activating outdoor lighting at dusk and switching it off at dawn. Used together, these technologies form the foundation of an automated, energy-efficient lighting control system.

RelightDepot carries a broad selection of occupancy sensors and photocell controls for commercial, industrial, and outdoor applications. Wall-switch occupancy sensors replace standard switches and require no additional wiring, making them easy retrofits for offices, restrooms, and conference rooms. Ceiling-mounted sensors cover larger open areas such as warehouses, gymnasiums, and parking garages. Outdoor photocell controls are available in shorting cap, locking twist-lock, and adjustable sensitivity configurations for streetlight and area light automation.

Browse our dedicated subcategories for targeted selection. See occupancy sensors for indoor motion-based control or photocell controls for outdoor daylight-responsive switching. Pair sensors with dimmers for enhanced dimming control, or browse our full switches selection for manual control alternatives.
