Abstract
An improved arc tube for a horizontal burning metal halide arc discharge lamp is disclosed to avoid light output fluctuations which otherwise occur during lamp operation. The improved arc tube construction employs opposing planar pinch seal regions which are angularly displaced with respect to each other while further positioning the opposing discharge electrodes below the longitudinal central axis of the arc tube member.
