Product Overview
This is a linear LED high bay fixture with adjustable wattage settings of 320, 400, or 500 watts. Output ranges from 48,960 to 76,900 lumens, with a maximum efficacy of 150 lumens per watt.
The fixture supports color temperature adjustment between 3500K, 4000K, and 5000K. It is designed to replace 1500 watt metal halide systems in commercial and industrial spaces.
Voltage compatibility is 100V to 277V. The fixture measures 39.5 by 12 by 2 inches and weighs 14.6 pounds.
Standard mounting is chain-cable, with an optional surface mount configuration. The fixture housing is aluminum alloy and finished in white.
Where This Product Fits Best
This fixture is suitable for large indoor spaces requiring high lumen output and flexible configuration. Typical applications include warehouses, manufacturing plants, and distribution centers.
It is designed for environments where legacy 1500 watt metal halide fixtures are being replaced. The adjustable wattage and color temperature allow adaptation to different lighting requirements within the same facility.
The fixture operates in ambient temperatures from -22°F to 122°F, supporting use in both conditioned and unconditioned spaces.
Chain-cable mounting is standard, with surface mounting available for locations where overhead suspension is not practical.
Performance and Functional Considerations
The fixture delivers up to 76,900 lumens at the highest wattage setting. Lumen output and color temperature can be set during installation to match application needs.
It provides a 120° beam angle for wide area coverage. The CRI is 80+, supporting accurate color rendering in work environments.
1-10V dimming is supported for integration with compatible dimming controls. The power factor is 0.90 and total harmonic distortion is 20% maximum.
The rated lifespan is 100,000 hours (L70), supporting long-term operation with minimal maintenance.
Installation and Long-Term Use
The fixture is designed for chain-cable mounting as standard, with an optional surface mount configuration. No cord is supplied, so field wiring is required during installation.
At 14.6 pounds, the fixture can be handled by a single installer for most mounting scenarios. The aluminum alloy housing provides durability in demanding environments.
Operating temperature range is -22°F to 122°F, allowing use in a wide range of facility conditions. The fixture is suitable for both new construction and retrofit projects.
Routine maintenance is limited to periodic cleaning and inspection, as the LED system is rated for extended service life.
How This Fixture Is Commonly Used
After installation, you can set the wattage and color temperature to match the lighting requirements of each area. This allows the same fixture to be used in different zones with varying light levels or color preferences.
The wide 120° beam angle provides uniform illumination across open floor areas, minimizing shadowing and dark spots. The fixture supports 1-10V dimming, so you can adjust light output as needed for energy management or task-specific needs.
Once installed, the fixture operates with minimal attention. The aluminum housing and high-rated lifespan reduce the need for frequent service or replacement.
In day-to-day use, the fixture maintains consistent output and color quality, supporting safe and productive work environments.
