270 / 340 / 400 Wattage Adjustable High Bay Linear | 41600 to 56100 Lumens | 4000K / 5000K Adjustable | 100-277V | 3 Foot 8 Inches

Product Overview

This linear LED high bay fixture offers selectable wattage settings of 270, 340, or 400 watts, delivering lumen outputs of 41,600, 50,000, or 56,100 respectively. The fixture is designed to replace 1000, 1500, or 2000 watt metal halide systems in commercial and industrial environments.

It operates on 100V-277V input and supports both 4000K and 5000K color temperatures, selectable at installation. The fixture uses a polycarbonate lens and provides a standard 90° beam angle for broad, even coverage.

The housing is constructed from galvanized rolled iron and finished in white. The fixture measures 44.2 by 10.2 by 1.8 inches and weighs 10 lbs.

0-10V dimming is supported. The fixture is rated for a 70,000 hour lifespan and is designed for chain-cable mounting, with pendant and surface mounting options available.

Where This Product Fits Best

This fixture is suited for large indoor spaces requiring high lumen output, such as warehouses, manufacturing plants, and distribution centers. It is intended for use in areas where legacy metal halide systems are being replaced with LED technology.

The selectable wattage and color temperature allow for adaptation to different ceiling heights and visual requirements. The fixture is compatible with standard 100V-277V electrical systems found in most commercial and industrial facilities.

It is suitable for environments with ambient temperatures ranging from -4°F to 122°F. The fixture's construction and ratings support use in demanding operational settings.

Performance and Functional Considerations

The fixture delivers up to 150 lumens per watt, providing high efficiency for energy-conscious operations. The 0-10V dimming capability allows for integration with lighting controls to manage output as needed.

The polycarbonate lens and 90° beam angle provide uniform light distribution, reducing glare and shadowing in work areas. The CRI of 80+ supports accurate color rendering for tasks requiring visual clarity.

Selectable wattage and color temperature features allow adjustment at installation to match site-specific requirements. The power factor of 0.98 and maximum THD of 20% support stable operation on facility electrical systems.

The fixture operates at 50 or 60 Hz, accommodating both frequency standards in commercial and industrial settings.

Installation and Long-Term Use

The fixture is designed for chain-cable mounting as standard, with pendant and surface mounting options available. No cord is supplied, so field wiring is required during installation.

The galvanized rolled iron housing provides durability in high-traffic or industrial environments. The fixture's weight and dimensions allow for manageable handling during installation by a two-person crew.

Rated for operation in temperatures from -4°F to 122°F, the fixture is suitable for both conditioned and unconditioned spaces. The 70,000 hour rated lifespan supports long-term use with minimal maintenance requirements.

Color and wattage can be set at installation to match application needs. The fixture is finished in white for a clean appearance in open or exposed ceiling environments.

How This Fixture Is Commonly Used

After installation, you can adjust the fixture's wattage and color temperature to match the lighting needs of your space. This is typically set during commissioning and remains fixed during day-to-day operation.

The 0-10V dimming interface allows you to connect the fixture to compatible dimming systems or controls, giving you flexibility to manage light levels as needed for different tasks or occupancy patterns.

The 90° beam angle provides broad coverage, reducing the number of fixtures needed in open areas. The polycarbonate lens helps maintain consistent light quality over time, even in environments with airborne dust or debris.

Routine maintenance is limited to periodic cleaning of the lens and visual inspection, as the fixture is designed for long service life without lamp changes.
