Ushio 5000789 MHR-100D/L 100W Fiber Optic Metal Halide Reflector Lamp - 95V, 5200K, AMP 3-Pin

OEM-style metal halide reflector lamp for fiber optic illuminators, microscopy, and optical inspection systems.
Designed with a cold mirror dichroic ellipsoidal reflector, 5200K daylight output, and AMP Universal Mate-N-Lok 3-pin connection for reliable equipment replacement.

Product Overview

The Ushio 5000789 MHR-100D/L is a 100W fiber optic metal halide reflector lamp engineered for fiber optic illuminators, microscopy light sources, machine vision systems, and optical inspection equipment. Its 5200K daylight output supports bright, crisp illumination for applications where color differentiation and optical clarity are important.

This lamp uses a cold mirror dichroic ellipsoidal reflector that helps redirect infrared heat rearward, which can reduce heat transfer toward fiber bundles and sensitive optical components. The factory-aligned reflector design also supports consistent replacement performance in compatible OEM systems.

An AMP Universal Mate-N-Lok 3-channel plug, 95V operating specification, and M90 ballast requirement make this lamp a specialized replacement component for equipment designed around this exact configuration.
