Zusammenfassung:	The electric lamp has a quartz glass lamp vessel (1) having first and second neck-shaped portions (2, 3) with first and second seals (4, 5). Current supply conductors (6, 7, 8; 9, 10, 11) consist of a metal foil (7, 10) embedded in the respective seal (4, 5), an inner (6, 9) and an outer current wire (8, 11) connected hereto. A seal ends with a closed fracture surface (14) through which an outer current wire (8, 11) extends. Favorably, the edge (13) of the fracture surface (14) has some small indentations (16) adjacent the origin of the fracture (19). The total length of the lamp is about 2 mm less than that of its conventional counterpart.
