Ushio 175W Metal Halide Bulb

The Ushio UMH-175/U/MD is a 175W metal halide lamp built for commercial and outdoor fixtures that require high-intensity discharge lighting. It delivers 14000 lumens at a 4000K colour temperature with a CRI of 65. The ED17 envelope fits standard E26 medium-base sockets.

Ballast ANSI Code M57/E

This lamp is rated for the M57/E ballast code, which dictates its electrical characteristics and mandates use in enclosed fixtures only. Installing it on any other ballast type will cause immediate failure or unsafe operation. Verify the fixture ballast label matches M57/E before purchase.

14000 Lumens and 10000-Hour Life

At full output the bulb suits large-area lighting such as warehouses, parking lots or high-bay retail spaces where 4000K neutral white is specified. Output will gradually decline over the 10000-hour rated life. It is not suited for applications needing high colour fidelity or instant restrike.

Questions about this item

How bright will the 14000 lumen output actually be in a real fixture?

The lamp delivers 14000 initial lumens at 4000K with a CRI of 65, providing high-intensity cool-white light suitable for large indoor or outdoor areas when operated on a compatible M57/E ballast in an enclosed fixture.

What does the M57/E ballast code mean for installation?

M57/E identifies the ANSI ballast type required; the bulb must be paired with an M57/E-rated ballast and used only in enclosed fixtures to meet its 10000-hour rated life and safety listing.

Will the ED17 bulb with E26 base fit my existing socket and housing?

It uses a standard E26 medium screw base and an ED17 envelope shape, so it fits medium-base sockets designed for ED17 metal halide lamps in enclosed fixtures.
