Product Overview

This LED high bay fixture delivers 6000 lumens at 40 watts, providing a direct replacement for 150 watt metal halide units. The fixture is available in 4000K or 5000K color temperatures and offers a CRI of 80+ for consistent color rendering in commercial and industrial environments.

Beam angle options include 10°, 25°, 40°, 90°, and 120°, allowing for targeted or wide-area illumination as needed. The fixture operates on either 100V-277V or 347V-480V input, supporting both standard and high-voltage applications.

It features a polycarbonate lens and an aluminum alloy housing finished in gray. The fixture is designed for use with either eye-hook or pendant mounting methods.

Rated for a 70,000-hour lifespan, this fixture is built for long-term operation in demanding environments. The power factor is greater than 0.95, and total harmonic distortion is less than 15%.

Where This Product Fits Best

This fixture is suited for commercial and industrial spaces where a 150 watt metal halide replacement is required. Typical applications include warehouses, manufacturing areas, and distribution centers.

The available beam angles support both focused and general lighting needs, making it suitable for high bay, task, or accent lighting. The fixture's voltage compatibility covers both standard and high-voltage installations.

With an IP66 rating and an operating temperature range from -40°F to 194°F, this fixture is appropriate for environments exposed to dust, moisture, or extreme temperatures.

Eye-hook and pendant mounting options allow for installation flexibility in a variety of ceiling structures and heights.

Performance and Functional Considerations

The fixture delivers 150 lumens per watt, supporting energy-efficient operation in retrofit or new construction scenarios. The polycarbonate lens provides impact resistance and optical clarity for consistent light output.

Multiple beam angle options allow for precise control over light distribution, from narrow spot to wide flood. The fixture does not support dimming.

Power factor above 0.95 and THD below 15% support stable operation on commercial electrical systems. The fixture operates at 50/60 Hz frequency.

Color temperature options of 4000K and 5000K allow for selection based on application requirements or user preference.

Installation and Long-Term Use

The fixture weighs 12 lbs and measures 8.5 x 12 x 8.65 inches, allowing for manageable handling during installation. Eye-hook and pendant mounting options accommodate common high bay mounting scenarios.

The aluminum alloy housing and polycarbonate lens are designed for durability in industrial settings. The IP66 rating allows for installation in areas exposed to dust and water jets.

The fixture is rated for operation in ambient temperatures from -40°F to 194°F, supporting use in both cold storage and high-heat environments.

With a 70,000-hour rated lifespan, the fixture is intended for long-term, low-maintenance operation. No dimming functionality is provided.

How This Fixture Is Commonly Used

Once installed, this fixture provides consistent, fixed-output illumination without the need for dimming adjustments. The selected beam angle determines whether the light is concentrated for task areas or spread for general coverage.

Operators can choose between 4000K and 5000K color temperatures to match existing lighting or meet specific visual requirements. The fixture's high CRI supports accurate color recognition in workspaces.

Routine maintenance is minimized due to the fixture's long rated lifespan and durable construction. The IP66 rating allows for straightforward cleaning and operation in dusty or wet environments.

Mounting method selection?eye-hook or pendant?affects how the fixture is accessed for inspection or cleaning, but both options support secure, stable installation in typical high bay settings.
