The duality of light measurement. Whether it’s directed or diffuse measurements – the Light Sensor Dual handles both! The challenge should not be underestimated. To obtain valuable information about the lighting situation in a room, it is not enough to simply determine the general brightness. It is important to combine the measurement, for example, at table height with the assessment of the diffuse room brightness. This way, error influences can be eliminated for better light regulation. And that's exactly what the STEINEL Light Sensor Dual is perfect for.
