The compact low-pressure discharge lamp (1) has a wound tubular discharge vessel (2) with at least four straight tubes (6, 7) which are in a polygonal arrangement and, close to or at the ends of the straight tubes (6, 7), are connected by transverse connections (8, 10, 11) to form a single continuous discharge path which is closed off in a gastight manner. A coil spring (14) made from metal, which runs parallel to the tubes (6, 7) is arranged in the center of the cylindrical cavity (13) formed by the straight tubes (6, 7) of the discharge vessel (2). The coil spring (14) reduces the firing voltage required.
