Osram M175/U/MED 175W ED17 Metal Halide Hid Lamp

Product Description

The OSRAM M175/U/MED is a 175-watt metal halide HID lamp in an ED17 envelope with an E26 medium screw base. Designed for probe-start ballasts, it operates on the M57/E ANSI ballast code and runs at 132 volts. Initial lumens reach 14400 depending on operating position, with a mean output of 9300 lumens, and a color temperature of 4000 K with a color rendering index of 65. The clear glass envelope and compact METALARC design make this lamp a practical choice for commercial and industrial lighting applications. Licensed electricians and lighting contractors typically source and install this lamp in high-bay, area, and outdoor fixture systems.

This lamp is suited for a wide range of commercial and industrial environments including area lighting, canopy lighting, parking lot lighting, street lighting, warehouse lighting, retail facilities, shopping malls, and sports lighting. Its universal operating position allows vertical or horizontal mounting depending on fixture design, though rated life varies by position: 10000 hours vertical and 7500 hours horizontal. The E26 medium base fits standard HID medium-base sockets commonly found in both indoor and outdoor luminaires.

Key Features

• 175-watt probe-start metal halide lamp, ANSI M57/E ballast compatible
• Universal operating position supports vertical and horizontal mounting
• Initial output of 11400 lumens vertical and 12800 lumens horizontal
• 4000 K color temperature with 65 CRI for balanced white light rendering
• Lead-free base and lead-free glass construction
• Compact ED17 envelope supports use in smaller luminaire designs

Compatibility

Designed for use with probe-start metal halide ballasts rated to ANSI code M57/E at 132 volts. Suitable for standard E26 medium-base HID sockets in area, canopy, street, parking lot, and industrial luminaires. Confirm ballast type and ANSI code match before installation.

Installation Notes

Installation should be performed by a licensed electrician. De-energize the fixture and allow the existing lamp to cool fully before handling, as metal halide lamps retain dangerous heat after shutdown. Hot restrike requires 7 to 12 minutes after power interruption before the arc re-establishes. Warm-up time to full output is 2 to 4 minutes. Always verify that the replacement ballast matches the ANSI M57/E specification to avoid premature lamp failure or ballast damage.
