Ambient Light Intensity; Multisensor Light Scale - Motorola MC4000 Quick Start Manual

Ambient Light Intensity

The built-in ambient light intensity sensor measures light in lux. Values
above 1200 lux are extrapolations.
The sensor will indicate a number from 0 to 10. The chart below
indicates the corresponding lux value. The MultiSensor is most
responsive to yellow light, and less responsive to blue and red light.
