Abstract
A metal halide lamp includes an arc tube and a surrounding tubular quartz sleeve between a wire frame. The wire frame is formed from a pair of substantially parallel wire frame members and a top section where the two frame members meet. The two frame members are mounted to a glass stem containing current supply leads. The sleeve is provided with two pairs of diametrically opposed apertures, each pair of apertures receiving an elongate wire U-clip which engages a pinched end of the arc tube inside the sleeve and the frame members outside the sleeve. A disk having a slot is inserted over a top section of the wire frame through the slot.
