ABSTRACT:
An improved construction for a lamp cap suitable for interconnecting the elongated constricted neck of a halogen lamp to an electrode-bearing lamp holder is described. A hollow elongated deformable insert is coaxially positioned within a conventional cover disc of the lamp cap. The interior dimension of the insert is chosen to effect a secure frictional engagement with at least 30% of the length of the constricted lamp neck, and is permanently or removably affixed to the surrounding cover disc. The lamp holder may then be affixed to the composite lamp cap to complete the assembly.
