Abstract
A compact screw-base discharge lamp having an electrical stabilization ballast which occupies a central position in the lamp. The discharge vessel surrounds the ballast. To dissipate the heat generated by the ballast during operation to the environment of the lamp, a thin-walled heat sink of a heat-conductive material is provided between the ballast and the discharge vessel, and bears on the ballast. This body has a collar which extends to the exterior of the lamp.
