Low-pressure mercury vapor discharge lamp comprising a, preferably folded, discharge tube located within a lamp envelope and having electrodes and an electric stabilization ballast, which is partly surrounded by a thin-walled lamp base, which is connected to the envelope. In the region of the connection between the lamp base and the lamp envelope there is a metal plate for cooling the ballast, this heat sink being at the same time a mounting plate for further components in the lamp such as a starter switch.
