Overview

The Sylvania 64439 SUPER METALARC 175W Metal Halide Lamp is engineered for commercial and industrial lighting applications where high-intensity, consistent illumination is essential. Producing 15,000 lumens at a color temperature of 4200K, this lamp delivers a neutral white light that supports accurate color perception in workspaces such as warehouses, manufacturing floors, and retail environments. The BT28 bulb shape paired with a mogul base ensures compatibility with a wide range of standard high-bay and flood light fixtures.

Designed exclusively for horizontal burn orientation, this lamp is optimized for fixtures mounted in that position, which is common in many industrial ceiling-mount and wall-mount applications. It operates on an M57/E ballast circuit, making it a straightforward replacement in existing metal halide systems. While metal halide technology requires a brief warm-up period to reach full output, the SUPER METALARC line from Sylvania is known for reliable performance and consistent lumen maintenance throughout the lamp's service life.
