ABSTRACT:
A lamp member is adapted for use in a lighting unit having a light transmitting cover. The lamp member comprises a base, a tungsten-halogen capsule supported within the base, a first envelope, and a filament structure axially oriented with the first envelope. The lamp member further includes spacer means for maintaining the lamp member and the cover in a spaced-apart relationship when the lamp member is in the spring-biased position within the housing. The spacer means is secured to the lamp member and is in operative contact with the cover. One example of the spacer means is a cylindrical cap made of a ceramic material, the cap being disposed at the top of the capsule and secured thereon. The cylindrical cap is dimensioned so that the size of the replacement lamp is substantially the same size as prior incandescent lamps of which the invention is designed to replace.
