Energy-Efficient Street Lighting with Zhaga Photocell Technology
The ALR 11000 Digital Photocell is a smart street lighting solution that combines on/off functionality with energy-saving dimming. It automatically dims lights during preset hours, reducing energy consumption and lowering costs. Compatible with the Zhaga-D4i ecosystem, it integrates seamlessly with Zhaga-D4i-certified luminaires and uses the Zhaga Book 18 interface for easy installation. The compact design enhances both aesthetics and sealing, while digital communication and advanced algorithms ensure optimal lighting control based on ambient light levels. It can work as a standalone control device or with a Zhaga-D4i motion sensor. The device monitors ambient light levels to switch the driver’s output on, off, and dim using the D4i protocol. Ideal for smart city applications, the ALR 11000 delivers efficient, cost-effective lighting solutions.
