A gas discharge lamp is disclosed which has a generally straight, tubular configuration and exhibits an approximately constant irradiation power along a greater portion of its length than previous lamps. This feature is achieved by forming the radiation body of the lamp into three sections along its length, a central sectors and two end sectors, wherein the central sector has different cross section than the two end sectors. In one embodiment, the central sector has a larger cross section than either of the end sectors.
