Abstract
A system and method for daylight harvesting and/or light management is provided in which a signal from a light sensor is filtered in order to determine the amount of light received from a light fixture in a lighting system and/or from an external light source, such as sunlight even if light is received from multiple light sources. By filtering the signals from the light sensor, an amount of light received from each light source may be determined, and correspondingly controlled to reach a target light level and/or a target balance of light from the multiple light sources.
