Abstract: A multiple element lamp includes an enclosure mounted on a base with a plurality of lighting elements mounted independently within the enclosure. The lighting elements are electrically connected to a control circuit in the base which selectively supplies power to the individual lighting elements. The control circuit will disconnect a lighting element upon the detection of a decrease in lighting efficiency of the element, and turn on another of the plurality of elements.
