A lighting system for discotheques includes a motor driven lamp unit which produces a variable direction light beam. A control device is provided remote from the lamp for controlling its operation, and in order to provide a distinctive visual effect, a control device is provided so that the lamp unit can only be moved by the motor while the lamp is de-energized.
