Abstract: A lamp structure having a sealed enclosure provided with a source of radiant energy. An annular resilient electrically conductive base member adapted to yield upon insertion into an electrical socket. The base member having a peripheral configuration which is substantially symmetrical with respect to its central vertical axis. At least one series of circumferentially spaced openings in the base member. The base member having an upper annular edge and a lower annular edge. At least one of the upper and lower annular edges being secured directly to a portion of the remainder of the lamp structure. An upper electrical insulator element secured to the sealed enclosure. A lower electrical insulator element separating the lower annular edge and a lower lamp contact element. Circuit means connecting the radiant energy source with the lower lamp contact element and the annular base member.
