ABSTRACT:
A spud made of refractory metal wire in the shape of a ring with a loop on each side radially aligns and provides electricity to a filament in a double ended tungsten halogen lamp. The spud has a leg extending from the end of each loop, one of which is attached to the filament and the other forming part of an inlead assembly. This spud is particularly useful with relatively small size double ended tungsten-halogen lamps having an infrared reflecting coating on the surface of the vitreous filament chamber.
