The invention relates to a lamp-holding device (1) which is capable of accommodating at least one light source (2) for emitting light. The lamp-holding device comprises a receiver (6) arranged to receive at least one electromagnetic signal (5) from a wireless controller (3). The lamp-holding device further comprises means (7) for sensing the intensity of said received electromagnetic signal and means (8) for controlling said at least one light source in accordance with said sensed intensity of said received electromagnetic signal. By sensing the intensity of the electromagnetic signal of the wireless controller at the lamp-holding device and controlling the behavior of the light source in such a way that it is dependent on the sensed intensity, the position of the wireless controller directly influences the behavior of the light source.
