Abstract: An illumination system includes several controllable lights and a mobile remote control for adjusting illumination properties of the lights, wherein the remote control includes a radio transmitter for transmitting control signals. The lights each have a radio receiver. Control signals sent from the radio transmitter of the remote control are receivable directly by radio receivers of the lights. The lights are controllable by their radio receivers involving the control signals transmitted by the radio transmitter of the remote control. The illuminating properties and/or the radiation characteristics of the lights are adjustable and controllable directly by the remote control in that the radio receivers of the lights receive control signals directly from the remote control and in that the lights are controlled by their radio receivers by the transmitted control signals.
