Abstract: A high-pressure discharge lamp may include an elongate ceramic discharge vessel, at the ends of which an electrode system with an electrode tip pointing towards the discharge is mounted in a seal, the seal being tubular, the discharge vessel having an aspect ratio of at least 1.5, the discharge vessel having a metal halide fill and a wall load of more than 25 W/cm2, wherein the lamp is configured for operation with longitudinal acoustic modulation, the specific rated power of the entire outer surface area of the discharge vessel lying between 17 and 22 W/cm2, while at the same time the wall load in a subregion of the surface area, which extends between the tips of the electrodes, lies in the range of between 28 and 40 W/cm2.
