ABSTRACT:
An electric lamp (e.g., tungsten halogen) including an elongated envelope with at least one sealed end portion of flattened configuration. Located on the sealed end portion is a conductive base member of hollow configuration which is electrically coupled to the lamp's lead-in conductor (which projects externally from the envelope) and which is located not only substantially about the sealed end portion so as to substantially surround the end but also extends over a part of the envelope's body portion to thereby substantially prevent breakage of the sealed end portion (e.g., during lamp insertion and/or removal).
