LT134 Long-Life Zero-Crossing Photocell

Municipal-Grade Photocontrol for Street & Area Lighting

The LT134 photocell is a long-life, zero-crossing electronic photocontrol specifically developed for municipal tender projects in Central and South America. Designed to comply with stringent electrical, environmental, and safety standards, LT134 fully meets the requirements of ANSI C136.10-2017 and UL 773, ensuring smooth approval and reliable performance in regulated markets.

Engineered for durability and stability, LT134 is widely used in street lighting, roadways, parking lots, security lighting, and commercial outdoor lighting systems. Its advanced zero-crossing technology effectively reduces inrush current, making it especially suitable for modern LED luminaires and large-scale municipal lighting networks.

By automatically switching lighting ON at dusk and OFF at dawn, LT134 helps municipalities reduce energy consumption, extend luminaire life, and ensure consistent lighting performance under varying environmental conditions.
