Our color sensor is True Color Sensor (MTCSiCF) from MAZeT with a filter function based on the color standard CIE 1931/DIN 5033. It was designed with measuring LED lights in mind. This is copied directly from the sensor's data sheet regarding the led measuring:
"LED lighting control management for solid-state lighting (SSL), LED spotlights, cabin lighting, day-light management / Human and Color Centric Lighting (HCL and CCL), Color Light Output (CLO), ambient light color detection / correction, (O)LED display control, and dynamic display color balancing, portable light color measurement, and digital light projection (DLP)".
This sensor is also stable over the entire product lifetime and resistant to external influences, such as temperature or aging drifts. Every Lumu Power is calibrated individually before it's packaged and no calibration is needed after that, due to the special interference filter technology the sensor is using.
