Key Features

• Dual Light Measurement: Measures both directed and diffuse light simultaneously for accurate, error-corrected brightness detection.
• Precision Sensing: Monitors room brightness and the area directly below the sensor for balanced, reliable readings.
• KNX Integration: Transmits light level data to KNX lighting management systems for automated daylight harvesting and constant-lighting control.
• Concealed Round Recessed Design: Flush-mounted round housing blends discreetly into ceilings for a clean, professional finish.
• Error Reduction: Combines multiple light measurements to minimise interference from reflections and glare.

Product Description

The Steinel Light Sensor Dual KNX Round Recessed delivers precise light measurement for intelligent KNX lighting control. Using dual photo-cell technology, it simultaneously measures directed and diffuse light, ensuring accurate detection of room brightness even in complex lighting environments.

By combining these measurements, the sensor reduces error from reflections, glare and surface variation. Integrated directly with KNX systems, it enables automated daylight harvesting, constant-lighting control and energy optimisation.

Its concealed, flush-mounted round design makes it ideal for offices, classrooms and commercial spaces where accurate ambient light measurement is essential and a discreet ceiling finish is required.
