Abstract
A ceramic metal halide lamp assembly (A) includes an elongated support or member wire (70) that provides both electrical connection and centering of the arctube within the lamp assembly. The support wire has at least one bent region (80) that extends over at least ninety degrees of the inner circumference of the capsule. Preferably, the bent region is disposed between the pinch seal region and the arc chamber so that it does not adversely impact on the desired beam pattern of the lamp assembly.
