An electric incandescent lamp has a filament having two incandescent portions interconnected by an intermediate non-lightemitting conductor. The filament is accommodated in a single ended, pinchsealed tubular glass envelope and is supported therein in that the intermediate conductor is embedded in an inner portion of a second pinch seal.
