Product Overview

The Sylvania 54312 is a metal halide lamp in the HSD 4ArXS Metal Halide family, built for professional applications where this exact ordering code, wattage, and voltage are specified by the fixture or equipment manufacturer. Metal halide lamps of this type are precision components – the arc gap, base configuration, and operating position requirements are engineered for a specific fixture design and are not generally interchangeable with other wattages or ordering codes in the same family.

Operating position for this lamp is specified as Any. Rated for 6000 hours of average life, this lamp should only be installed in equipment that explicitly calls for the Sylvania 54312 or its 4ARXS HSD 150W/UL/75 ordering abbreviation.
