Abstract
A molded lamp base receives a press seal of a lamp. Internal walls of the base define a cavity open at one end to receive the press seal portion of the lamp. The side walls have a thickness dimension and a width dimension substantially conforming to the peripheral dimensions of the press seal portion. At least one raised bead extends inwardly from the cavity side wall and is dimensioned for a friction fit with the periphery of the lamp to hold the lamp securely in base. In one embodiment, the beads are located in semi-circular recesses disposed about the exhaust tube portion of the lamp while in another embodiment, the beads are spaced outwardly therefrom.
