METALARC POWERBALL Ceramic T lamps meet today’s color critical needs by combining conventional metal halide pulse start characteristics, such as good efficacy and long life, with improved lamp-to lamp color consistency and high CRI. Compared to conventional quartz metal halide products, SYLVANIA ceramic arc tube metal halide lamps exhibit less color variation and higher efficacy. Their high mean lumens, excellent color characteristics and compact size allow them to be used in a wide variety of applications. METALARC POWERBALL Ceramic lamps operate on existing ANSI specified magnetic ballasts and on compatible electronic ballasts. The lamps can be used in appropriate existing fixtures designed for metal halide lamps of similar wattages and configurations.
