The first and second tube are interconnected via tube interconnection means (10; 20; 30) at a first end portion (11a, 12a;21a, 22a;31a,32a). A discharge path is formed through the tubes between two electrodes (13; 33). Each electrode is provided at a second end portion (11b; 32b) of one of the tubes (11; 32). Further second end portions (12b; 21b; 22b; 31b)are provided with respective sealed ends (12c; 21c; 22c; 31c). Bridge parts (50; 60) for interconnecting tubes (12,21; 22,31) of mutually adjacent dual-shaped lamp parts (1,2; 2,3) are provided in the proximity of the second end portions (12b,21b; 22b,31b). At least one of the sealed ends (21c) is provided with an exhaust tube (71) which is directly provided on the respective sealed end.
