A lamp assembly that comprises a hollow arc discharge light source having a center arc chamber containing an arc generating and sustaining medium and first and second ends with an electrode receiving capillary extending from each end and arrayed along a longitudinal axis. The ends are cylindrical in cross-section. An electrode structure is positioned in each of the capillaries and each of these electrode structures comprises a proximal electrode end projecting into the interior of the center arc chamber, a distal end projecting exteriorly of said capillary and an intermediate section therebetween. A first area of the intermediate section is sealed to the capillary in an hermetic manner and a second area of the intermediate section is exposed to the medium. A tubular shroud surrounds the light source and is coaxial with the longitudinal axis. The shroud has two ends. A pair of spring clips, one at each end of said shroud, mount the light source within the shroud. Each of the spring clips comprises a base in a first plane and has an aperture centrally located therein, each apertur e of one of the spring clips frictionally engaging one of the cylindrical ends of the light source at a position adjacent the second area of the intermediate section. Both spring clips are electrically connected to a frame, which is electrically to one of the electrode structures.
