Abstract: An irradiation apparatus having a housing, a reflector and a source of ultraviolet radiation. The irradiation apparatus has a timing mechanism detachably located within the housing, the timing mechanism being an integral portion of the circuit which supplies power from a power source to the ultraviolet radiation source. The timer is adapted to be removed from the housing and attached to the housing by means of a cord having a non-standard plug to allow the lamp to be operated by means of the timer from a remote position.
