A 1000 watt arc discharge arc tube assembly comprises two series connected side-by-side arc discharge tubes whose combined break down voltage in sufficient for a standard 2-5 kv starting pulse to simultaneously start both arc tubes without additional structure. A standard ballast, starter and fixture can be used with the arc tube assembly whose overall length is less than 300 millimeters. The lamps are spaced sufficiently apart to preclude detrimental heat transfer effects on one another and sufficiently close to act as a single source of light in standard fixtures normally employing lamps having a single discharge tube.
