Abstract: A lamp socket assembly (18) that can be used with a replaceable incandescent lamp (22) in applications where it is desirable or necessary to limit outgassing of the socket assembly. The socket assembly (18) comprises a plastic socket made from polyetherimide, with the socket having an opening (50) to receive a press-sealed end (40) of the incandescent lamp (22). A plurality of electrical contacts (34) are located in the opening (50) and the socket (18) also includes a plurality of terminals (36), each of which is electrically connected to one of the contacts. The socket (18) includes at least one flexible retaining member (52) located at the opening (50) to engage the press-sealed end (40) of the incandescent lamp (22) and thereby retain the lamp within the opening. The socket (18) comprises a housing (30) and a separate body (32) integrally attached to the housing, with both the body and housing being made from the polyetherimide.
