Abstract

An electric lamp whose envelope 60 has at least two sections 62, 64 which are hermetically joined together, in which the envelope preferably has a coating 67 of a visible light transmissive and infrared reflective material thereon and in which the sections can be optically treated to accept and enhance the effectiveness of the coating. A method is also disclosed for making lamps using the multi-section envelope in which the envelope sections are hermetically sealed together after the envelope is exhausted or sealed in an environment the same as that to be contained within the envelope. <IMAGE>
