Product Overview

This is a 300 Watt LED linear high bay designed for commercial and industrial applications requiring high-output lighting. The fixture delivers 40,800 lumens at 136 lumens per watt and is built to replace 1000 Watt metal halide systems.

Color temperature is selectable between 4000K and 5000K. The fixture operates on 277V to 480V input and supports 0-10V dimming. The standard beam angle is 110°, with a frosted lens for glare control.

The housing is galvanized rolled iron, finished in white. The fixture measures 46.5 inches by 18.9 inches by 2.2 inches and weighs 18 pounds.

Mounting options include chain-cable as standard, with pendant and surface mounting available. The fixture does not include a cord.

Where This Product Fits Best

This fixture is suited for large indoor spaces with high ceilings, such as warehouses, manufacturing plants, and distribution centers. It is designed for environments where legacy 1000 Watt metal halide fixtures are being replaced.

The 277V-480V voltage range supports compatibility with common industrial electrical systems. The fixture operates reliably in ambient temperatures from -22°F to 113°F.

Color temperature selection between 4000K and 5000K allows adaptation to different visual tasks or user preferences. The 110° beam angle provides broad, even coverage in open areas.

The galvanized iron housing and UL listing support use in demanding commercial and industrial settings.

Performance and Functional Considerations

The fixture provides 40,800 lumens at 300 Watts, supporting high-illumination requirements. The 80+ CRI supports accurate color rendering for most industrial and commercial tasks.

0-10V dimming is supported for integration with compatible dimming controls. The power factor is .98, and total harmonic distortion is 20% max.

The frosted lens reduces glare and helps distribute light evenly. The fixture is color adjustable between 4000K and 5000K, selectable at installation.

L70 rated lifespan is 200,000 hours, supporting long-term use with minimal maintenance requirements.

Installation and Long-Term Use

Standard mounting is chain-cable, with pendant and surface mounting options available. The fixture does not include a cord and requires field wiring during installation.

The housing is galvanized rolled iron for durability in industrial environments. The fixture weighs 18 pounds and measures just under 4 feet in length.

Operating temperature range is -22°F to 113°F, allowing use in both cold storage and heated facilities. The fixture is designed for indoor use where UL listing is required.

Long-term maintenance is minimized by the 200,000-hour L70 lifespan and robust construction.

How This Fixture Is Commonly Used

Once installed, you can select either 4000K or 5000K color temperature to match the visual needs of your space. This is set during installation and remains fixed during operation.

The 0-10V dimming feature allows you to adjust light output using compatible dimming controls, supporting energy management or task-specific lighting levels.

The frosted lens helps reduce glare for personnel working below the fixture, making it suitable for areas with frequent foot or forklift traffic.

Routine operation is hands-off, with no lamp changes or frequent maintenance required due to the long LED lifespan and durable housing.
