• Error reduction: Combines multiple light measurements to minimise interference and reflection errors.

• DALI-2 Input Device: Transmits sensor data to higher-level DALI-2 lighting management systems.

• Smart control integration: Enables automated adjustment of lighting levels based on ambient light conditions.

• Surface-mounted design: Square housing for easy installation in visible ceiling applications.

• Reliable performance: Designed for long-term stability and consistent measurement accuracy.

Product 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.
