About Photocells

Photocells control outdoor lighting automatically by responding to ambient light levels. When daylight drops below a set threshold, the photocell triggers the connected fixture to switch on; it switches off again at dawn. This keeps parking lots, wall packs, canopy lights, and area fixtures running only when needed, without manual scheduling.

QuickShipLights stocks the most common configurations: twist-lock NEMA sockets for standard outdoor fixtures, button-style photocells for direct mounting, and integrated assemblies built into specific fixture types. Twist-lock photocells pair with the NEMA receptacle found on most commercial outdoor fixtures, making replacement straightforward.

Key specs to match: voltage (120V, 240V, or 277V), ampere rating, and wire lead length for direct-wire models. Some photocells offer adjustable turn-on thresholds to avoid nuisance switching in environments near artificial light sources.

Pair photocells with LED Wall Packs and LED Parking Lot Lights for a complete outdoor control solution. For movement-activated control, see Motion Sensors. Switches and dimmers are in Wiring Devices.
