A method of determining the power consumption of a lighting device, the lighting device comprising a lamp unit for emitting illumination to illuminate a space, and a powering device which supplies an electrical power signal to power the lamp unit to emit said illumination. The method comprises: storing power consumption data of a plurality of types of powering device under different lamp unit loading conditions; at the lamp unit, determining a type of the powering device to which the lamp unit is coupled; at the lamp unit, determining an operating status of the lamp unit; determining the corresponding power consumption of the powering device from the stored power consumption data, based on the determined type of powering device, and the operating status of the lamp; and calculating the total power consumption of the lighting device as the sum of the power consumption of the powering device and the lamp unit.
