Abstract: The discharge lamp (10) comprises a casing (20) made of glass, which surrounds the discharge vessel (16). The glass material of the casing is doped with sodium in a concentration of at least 10 ppm by relation to the weight, and preferably of at least 30 ppm. The glass material of the casing may contain, in addition to sodium, other alkali metals in a maximum concentration of totaling 25 ppm by relation to the weight. The discharge lamp comprises a socket (12) and a burner (14). The burner comprises a discharge vessel, lead wires (18), and a casing. The discharge vessel and the lead wires are formed as a single-piece glass body. Electrical conductors are in the lead wires, which are connected to electrodes (22) in the interior space of the discharge vessel. By the imposition of a voltage at the connections (24), which are connected to the electrodes, a gas discharge can be induced in the interior of the discharge vessel.
