The duality of light measurement. Whether it’s about directional or diffuse measurements – the Light Sensor Dual handles both! The challenge should not be underestimated. To obtain usable information about the light 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 control. And for this purpose, the STEINEL Light Sensor Dual is simply perfect.
