Abstract: The invention is directed at a method and system for controlling lighting in an enclosed space. A daylight harvesting apparatus for controlling an amount of light in an associated work area comprises a sensor assembly for sensing an amount of illumination in a proximity of the apparatus; a controller for receiving a value representing the amount of illumination and for determining an lamp control signal to be provided based on the amount of illumination; and an artificial light source for providing light, corresponding to the lamp control signal, to the work area.
