LT655B Heavy-Duty 480V 15A Receptacle — Pair with Photocell Controllers for Reliable Automatic Lighting Control

High-Durability External Socket for NEMA Photocell Controllers & Outdoor LED Lighting

The LT655B External-Mount Photocell Receptacle is a BS5972-compliant, heavy-duty socket designed for outdoor luminaires requiring quick installation, high-voltage operation, and long-term reliability. Unlike traditional receptacles that must be built inside the lamp body, LT655B’s external-mount design allows manufacturers to upgrade any luminaire with a NEMA interface—without redesigning internal structures, making it ideal for both new fixtures and retrofit projects.

Built with anti-UV, impact-resistant polycarbonate (PC) and engineered for harsh climates, the LT655B supports 480V / 15A max load, excellent insulation performance, and stable connection to photocell controllers, ensuring precise dusk-to-dawn automation.
