Osram M100/U/MED 100W ED17 Metal Halide Hid Lamp E26

Product Description

The OSRAM M100/U/MED is a 100-watt pulse-start metal halide HID lamp built for demanding commercial and industrial lighting applications. The lamp features an ED17 bulb shape, an E26 medium screw base, and operates at 100 volts with a universal burn position. Initial output is 8,500 lumens, dropping to a mean of 4,675 lumens over rated life. Color temperature is 4000 Kelvin with a Color Rendering Index of 75, producing a clean, neutral white light suited to high-ceiling and area lighting environments. The METALARC PRO-TECH design incorporates a glass shroud for optical containment and UV reduction, allowing use in both open and enclosed fixtures.

This lamp is specified for industrial and retail facilities, lobbies, atriums, malls, parking lots, security lighting installations, and general floodlight applications. The pulse-start ignition method supports reliable cold starting and reduces electrode wear versus probe-start designs. The E26 medium base allows direct retrofitting into standard mogul-style sockets already wired for compatible M90/E ballasts. Licensed electricians and lighting maintenance contractors typically install and replace this lamp type in commercial fixtures across new construction and renovation projects.

Key Features

• Pulse-start ignition for reliable starting and extended electrode life
• METALARC PRO-TECH glass shroud provides UV reduction and containment in open or enclosed fixtures
• 8,500 initial lumens with a rated lamp life of 12,000 hours
• 4000 Kelvin neutral white output with a CRI of 75
• Universal operating position for flexible fixture mounting
• Retrofits into standard E26 medium base sockets without rewiring
• Warm-up time of 2 to 4 minutes; hot restrike time of 5 to 7 minutes

Compatibility

Compatible with M90/E rated ballasts. Suitable for use in both open and enclosed fixtures. Per NEC 2005 and later revisions, new construction and major renovations require open-rated lamps to be used with exclusionary sockets in open fixtures, or in suitably enclosed fixtures with a lens.

Installation Notes

Installation and replacement should be performed by a qualified electrician or licensed lighting contractor with the circuit de-energized and the fixture allowed to cool fully before handling. Verify ballast compatibility with the M90/E ANSI code prior to installation. Handle the outer glass envelope with clean gloves to prevent contamination that can reduce lamp life or cause thermal stress. Comply with all applicable NEC requirements and local electrical codes governing HID luminaire installations.
