An electrodeless low-pressure discharge lamp has a tube of synthetic material in a cavity in the discharge vessel, which tube surrounds a core of magnetic material and is itself surrounded by an electric coil. The tube is bipartite, extends to outside the cavity, and has a flange which is fastened to a mounting plate and is coupled to the discharge vessel. A heatpipe extending inside the tube has a second flange clamped between the flange of the tube and the mounting plate.
