摘要：
A quartz arc tube for a metal halide lamps and its method of making are described. The quartz arc tube has a cylindrical design which promotes a nearly symmetric longitudinal surface temperature profile during operation. The profile has a maximum temperature of about 900° C. which allows for longer operating life at high average wall loadings.
