Abstract

A lamp with re-enforced tubular base pins is disclosed. A less expensive, high quality, high wattage lamp may be formed with re-enforced tubular base pins. The lamp comprises a lamp envelope having an enclosed means for producing light, a light transmissive envelope, and at least two electrical connections, a ceramic lamp base for holding the lamp envelope, and the two tubular pins. Each pin comprises an electrically conductive tube having an exterior surface along which a compressive coupling may be made, and an interior surface defining an internal volume. A fill cement is positioned in the internal volume of each base pin at least along the portions opposite where compressive coupling may be made to the exterior surface of the pin.
