Product Overview
The Sylvania 54066 is a metal halide lamp in the HMI 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 750 hours of average life, this lamp should only be installed in equipment that explicitly calls for the Sylvania 54066 or its HMI 1200 W/GS ordering abbreviation.
Compatible Applications
- Professional fixtures and equipment specified for the Sylvania 54066 (HMI 1200 W/GS)

Before Ordering – Verify
- Confirm your equipment specifies the Sylvania 54066, ordering abbreviation HMI 1200 W/GS
