1. A system for light management comprising:

  • a sensor configured to generate a sensor signal that indicates an amount of light detected in a lighting area by the sensor;

    a filter configured to generate a filtered signal from the sensor signal such that the filter at least partially blocks a component of the sensor signal representing light from a first light source and at least partially passes a component of the sensor signal representing light from a second light source, the first light source including a light fixture that illuminates the lighting area, the filtered signal indicating an amount of light in the lighting area received from the second light source; and

    a light management module configured to determine a target amount of light to be received from the first light source in the lighting area based on a target light level for the lighting area and on the filtered signal indicating an amount of light in the lighting area received from the second light source,wherein the light management module is further configured to cause the light fixture to be powered at a target power level at which the light fixture generates the target amount of light,wherein the light fixture included in the first light source comprises a first light fixture, and wherein the second light source comprises a second light fixture that the light management module is not configured to control.
