Sylvania 64469 M1000/U/BT37 1000W 3800K E39 Metal Halide Lamp

The Sylvania 64469 M1000/U/BT37 Metalarc 1000W Metal Halide Lamp is a high-output HID replacement bulb engineered for large-scale industrial, commercial, and outdoor lighting systems requiring ANSI M47/E ballast compatibility. This probe-start metal halide lamp features a durable BT37 bulb shape, E39 mogul screw base, and delivers powerful cool white illumination for demanding high-mount applications including stadium lighting, warehouse high-bays, parking lot fixtures, floodlights, and manufacturing facilities. Designed for use in enclosed luminaires, the lamp provides dependable startup characteristics, strong lumen maintenance, and broad operating position flexibility for maintenance-intensive commercial environments.

ADL Supply Expert Application & Replacement Guide

The Sylvania M1000/U/BT37 is widely used in commercial high-bay fixtures, outdoor pole lights, sports complex floodlighting systems, industrial manufacturing facilities, airport lighting infrastructure, and large-area warehouse luminaires operating on ANSI M47 magnetic ballast systems. Its universal burn position allows installation in vertical, horizontal, or angled fixture orientations without compromising arc stability or operating performance.

This lamp is commonly specified as a maintenance replacement for legacy 1000W metal halide systems where facility managers require high lumen output without performing full LED fixture conversions. Contractors servicing older HID systems should inspect capacitors, ignitors, mogul sockets, and ballast housings for heat damage or voltage irregularities prior to relamping to prevent premature lamp cycling or startup failure.

The probe-start ignition design eliminates the need for an external ignitor while maintaining compatibility with standard M47 core-and-coil magnetic ballast configurations. When replacing aged lamps in gymnasiums, parking lots, or industrial facilities, replacing lamps in complete fixture groups is recommended to maintain consistent lumen output and uniform color appearance throughout the lighting layout.

Operation, Safety & Mounting Compliance

Warm-Up & Restrike Operation

This metal halide lamp requires approximately 5 to 10 minutes to achieve full lumen output and color stabilization after startup. Following power interruption, a hot restrike cooldown period of approximately 7 to 12 minutes is required before the lamp can successfully restart.

Fixture Ventilation & Thermal Conditions

The M1000/U/BT37 must be operated in properly ventilated enclosed fixtures designed for 1000W HID systems. Excessive fixture temperatures or inadequate airflow may negatively impact arc tube stability, lumen maintenance, and overall service life.

Mounting & Burning Position

This lamp supports universal operating positions, making it suitable for vertical base-up, base-down, horizontal, and angled mounting applications commonly found in sports lighting arrays and outdoor floodlighting systems. Always verify mogul socket integrity and fixture clearance dimensions before installation.

Environmental & Recycling Compliance

This lamp contains mercury and must be disposed of in accordance with local, state, and federal environmental regulations. Commercial recycling programs are strongly recommended for large-scale maintenance relamping projects and facility retrofit operations.
