Product Overview

The GE 43829 (MVR400/C/U) Coated Multi-Vapor® Metal Halide Lamp is a powerful 400-watt HID solution delivering an impressive 40,000 initial lumens. This version features a diffuse coating on the ED37 bulb, which effectively masks the intense arc tube to reduce direct glare and provide a more uniform, softened light distribution. The 3700K cool white light is ideal for large indoor spaces where visual comfort and high light levels are equally important.

Engineered for versatility, this lamp supports a universal burn position, making it compatible with any fixture orientation. With a robust 20,000-hour rated life and standard E39 mogul base, it serves as a dependable, long-lasting replacement for industrial high-bay systems, retail environments, and warehouse facilities operating on ANSI M59 ballasts.
