Abstract
The invention relates to a light control system () for controlling a lighting system (). The light control system () is arranged to receive a power reduction parameter (alpha). The light control system comprising a light controller () arranged to receive a measured light value from a light sensor (), to determine a light channel level value depending on the measured light value and a calibrated setpoint value if no power reduction parameter has been received, and to determine a light channel level value depending on the measured light value and a scaled calibrated setpoint value if the power reduction parameter has been received, the scaled calibrated setpoint value being equal to the calibrated setpoint value multiplied by the power reduction parameter. A load controller () is arranged to receive the light channel level value from the light controller, to determine an output level signal depending on the light channel level value if no power reduction parameter has been received and to determine a scaled output level signal if the power reduction parameter has been received, the scaled output level signal being equal to the output level signal multiplied by the power reduction parameter, and to send the output level signal or the scaled output level signal to drivers of light sources of the lighting system.
