Abstract
The electric lamp has a glass lamp vessel (1) having seals (3) from which an external metal wire (6) extends. A bare corrosion resistant contact wire (7), having a specific resistance of less than 0.8 .mu..OMEGA.m and a hardness of 50-300 HV is welded, e.g. butt-welded to the external metal wire (6). The contact wire (7) has an axial free end portion (8). An transversally extending intermediate portion (9) may be present between the seal and the free-end portion (8). The lamp allows secure electrical connections to a luminaire easily and rapidly to be made.
