The JL-242 Smart Dimming Photocontrol is designed to automatically control dimmable LED street lighting (0-10V) based on ambient natural lighting levels. Featuring microprocessor circuits with IR-filtered phototransistor technology, this product ensures reliable performance in various lighting conditions.
A heavy-duty surge arrester (MOV) provides protection against inrush current and lightning impulses, while a preset 10-second time-delay prevents excessive operation from spotlights or lightning during nighttime. The relay offers exceptional reliability with a work life exceeding 10,000 cycles, extendable with the optional sandwich cover.
This photocontrol features twist lock terminals meeting ANSI C136.41 requirements and is UL listed under ANSI/UL773 standards for plug-in, locking type photocontrols used with area lighting.

It is an intelligent photocontrol that supports 0-10V dimming, constant illumination control, midnight energy-saving mode, and real-time fault detection for outdoor and public lighting systems.
It senses ambient light in real time and outputs a 0-10V analog signal to adjust brightness automatically, keeping the illuminated area at a stable brightness level for energy efficiency and uniform lighting.
It automatically dims the lights to a lower brightness level during late-night hours, reducing power consumption while maintaining basic safety lighting for roads, passages and communities.
It continuously detects lamp working status, including lamp failure, short circuit, voltage abnormality, and dimming failure, and sends timely alarm feedback for quick maintenance.
It is widely used in street lighting, garden lights, corridor lighting, campus lighting, residential area lighting and other scenes needing intelligent dimming and fault monitoring.
