300 Watt LED Linear High Bay | 40800 lumens | 4000K / 5000K Color Selectable | 277-480V | 3 Foot 11 Inches

Product Overview

This 300 watt LED linear high bay delivers 40,800 lumens at 136 lumens per watt, replacing 1000 watt metal halide fixtures. The fixture operates on 277-480V input and includes field-selectable color temperature with 4000K and 5000K options built into the driver.

The housing is galvanized rolled iron with a white finish. Overall dimensions are 46.5 inches long by 18.9 inches wide by 2.2 inches deep, with a fixture weight of 18 pounds. A frosted lens provides 110-degree beam distribution.

Standard mounting is chain or cable suspension. Pendant and surface mounting are also supported. The fixture ships without a cord.

Where This Product Fits Best

This fixture is sized for high-output applications where 1000 watt metal halide fixtures are currently installed. The 277-480V input voltage makes it suitable for commercial and industrial electrical systems running higher voltage distribution.

The operating temperature range of -22 degrees F to 113 degrees F supports installation in cold storage environments, unheated warehouses, and spaces with elevated ambient temperatures. The linear form factor and 110-degree beam angle work well in aisle-oriented layouts and open floor areas requiring broad, even coverage.

Performance and Functional Considerations

Output is fixed at 300 watts and 40,800 lumens. Color temperature is selectable between 4000K and 5000K at installation or any time access to the fixture is available. CRI is 80 or higher.

The driver supports 0-10V dimming for integration with building management systems or manual dimmer controls. Power factor is 0.98 with THD at 20 percent maximum. The fixture operates on both 50 Hz and 60 Hz electrical systems.

Rated lifespan is 200,000 hours to L70, which defines the point at which output drops to 70 percent of initial lumens.

Installation and Long-Term Use

Chain or cable mounting is included as standard. Pendant and surface mount options are available for installations requiring different attachment methods. The fixture weighs 18 pounds and measures just under four feet in length, which affects handling during installation and the structural capacity required at the mounting point.

No power cord is included. Electrical connections are made directly to the fixture. The galvanized rolled iron housing resists corrosion in typical industrial environments.

Color temperature selection is accessible without tools or additional components. This allows adjustments during commissioning or future changes based on task requirements or occupant preference.

How This Fixture Is Commonly Used

Facilities replacing 1000 watt metal halide use this fixture to maintain or exceed previous light levels while reducing energy consumption. The 277-480V input matches the voltage infrastructure common in manufacturing plants, distribution centers, and large commercial spaces.

The 0-10V dimming input connects to existing building automation systems or standalone dimmers. This allows output reduction during low-activity periods or daylight harvesting scenarios where compatible controls are already in place.

The field-selectable color temperature lets maintenance teams or facility operators shift between 4000K and 5000K based on the visual environment. Cooler 5000K output is often used in task-heavy or inspection areas. Warmer 4000K output is common in general warehouse or retail back-of-house applications.

Safety, Certifications, and Warranty

This fixture is UL listed and rebate eligible. The 5-year warranty covers defects in materials and workmanship under normal operating conditions.
