The compact fluorescent lamp comprises a bulb shaped outer envelope enclosing a discharge tube having a coiled configuration and a ballast unit for controlling the current in the tube. The lamp further comprises at least one joint mechanical support and starting aid means for positioning the discharge tube and the ballast unit and reducing a breakdown voltage path of the discharge tube. The at least one mechanical support and starting aid means is made of an electrically conducting material and connected electrically to at least one of the electrodes. The neck portion has a retaining member, and the mechanical support and starting aid means is supported by the retaining member and clamped on the discharge tube at least at a location in a vicinity of a middle section of the arc path. The mechanical support means further comprises at least one support section to provide support against an apex of the outer envelope, and at least one fixing section for fixing of the discharge tube.
