    (54) High-pressure gas discharge lamp


    (57) The high pressure discharge lamp has a discharge vessel (6) within an outer bulb (1). A portion of a current supply conductor (11) is enveloped by an insulator (12) at the area where said conductor issues from the seal (2) of the outer bulb (1). An adjacent current lead (8) is enveloped by an insulator (13) which is fastened to the discharge vessel (6) where said conductor leaves the discharge vessel. Flash-over within the outer envelope upon the application of a high voltage to re-ignite the lamp in the hot state is thereby counteracted.
