G E Lighting 30953 400W Metal Halide Lamp ED37 Mogul

Product Description

The G E LIGHTING 30953 is a 400-watt clear multi-vapor metal halide lamp designed for high-intensity commercial and industrial lighting applications. Built in the ED37 bulb shape with a mogul base, this lamp delivers 36,000 initial lumens at a 4000 Kelvin color temperature, producing a crisp, neutral white light output suited to large spaces. The CRI rating of 65 is typical for metal halide sources used in industrial and commercial settings. Licensed electricians and facility maintenance technicians are the primary installers for fixtures using this lamp type.

This lamp is rated for universal burn position, making it flexible across fixture orientations — horizontal, vertical, or any angle. It is well suited for high-bay fixtures, warehouse lighting, gymnasium lighting, outdoor area lighting, and sports lighting. The lamp is compatible with both open and enclosed fixtures, expanding its range of viable applications. With a rated 20,000-hour lamp life and 90% lumen maintenance at 50% of rated life, this lamp reduces replacement frequency in demanding commercial environments.

Installation Notes

Metal halide lamp replacement is typically performed by a licensed electrician. Always de-energize the fixture and allow the existing lamp to cool completely before handling — operating temperatures on HID lamps are extremely high. Metal halide lamps require a compatible ballast; verify M59 ANSI ballast compatibility before installation. Allow adequate warm-up and restrike time after power is restored, as is standard for HID light sources.
