Description

The Steinel Light Sensor Dual DALI-2 Input Device – Surface, Square delivers precise light measurement for intelligent lighting control systems. Using dual photo-cell technology, it simultaneously measures both directed and diffuse light, ensuring accurate detection of room brightness even in complex lighting environments.

 

By combining these measurement results, the sensor effectively reduces error influences caused by reflections, glare, or varying surface conditions. Integrated as a DALI-2 Input Device, it communicates real-time light data to higher-level lighting management systems, enabling automated daylight harvesting, constant light control, and energy optimisation.

 

With its surface-mounted square design, the Light Sensor Dual is ideal for modern offices, schools, and commercial spaces where precise ambient light measurement is critical for performance and comfort.
