Direct Wire-in Photocontrol

Longjion Intelligence's JL-1 series is a thermally activated mechanical photocontroller that complies with the UL 773A standard. It features diverse designs and voltage coverage ranging from 120V to 277V. Based on ambient light intensity, it autonomously regulates lighting and is equipped with a delay function to prevent accidental triggering. The JL-4 series, on the other hand, adopts an electronic design with a wide voltage range, also adhering to UL 773A. It utilizes red, white, and black wires for connection, facilitating easy installation and testing, while offering a rapid response. With a broad voltage range and a preset delay to avoid misoperations, both series have passed multiple certifications, ensuring quality. They are suitable for passageway and entrance lighting, providing intelligent lighting solutions tailored to customer needs.
