230 / 260 / 300 Watt Adjustable Linear LED High Bay | 34500 to 45000 Lumens | 4000K / 5000K Adjustable | 100-277V or 277-480V | 3 Foot 8 Inches

Product Overview

This is an adjustable linear LED high bay fixture designed for industrial and commercial spaces requiring high-output lighting. Output is selectable between 230, 260, and 300 watts, delivering 34,500 to 45,000 lumens. The fixture is engineered to replace 1000 watt metal halide systems with a 150 lumens per watt efficiency.

Color temperature is field adjustable between 4000K and 5000K. The fixture supports both 100-277V and 277-480V input ranges. It is 44.3 inches long, 12.6 inches wide, and 3 inches high, with a total weight of 11 pounds.

The housing is die-cast aluminum with a white finish and a frosted lens for glare control. The fixture is 0-10V dimmable and includes surge protection rated at 6kV. Rated lifespan is 100,000 hours (L70).

Chain-cable mounting is supported. The fixture is UL listed and DLC Premium qualified. A motion sensor is available for occupancy-based control.

Where This Product Fits Best

This linear LED high bay is suited for large indoor spaces with high ceilings, such as warehouses, manufacturing plants, and distribution centers. It is intended for applications where high lumen output and energy efficiency are required.

The adjustable wattage and color temperature allow for adaptation to different lighting needs within the same facility. The fixture is compatible with both standard and high-voltage electrical systems, supporting a range from 100V to 480V.

Operating temperature range is -40°F to 113°F, making it suitable for environments with wide temperature fluctuations. The 120-degree beam angle and frosted lens provide broad, even illumination for open areas.

Performance and Functional Considerations

The selectable wattage feature allows adjustment of light output to match specific area requirements or energy targets. The fixture delivers up to 45,000 lumens at maximum setting, with a minimum of 34,500 lumens at the lowest setting.

Color temperature can be set to either 4000K or 5000K, supporting both neutral and cool white lighting preferences. The fixture maintains a color rendering index (CRI) of 80+ for accurate color visibility in work environments.

0-10V dimming is supported for integration with lighting controls or building management systems. Power factor is rated at 0.90, and total harmonic distortion (THD) is limited to 20% maximum.

Surge protection is built in at 6kV, providing resilience against electrical disturbances. The fixture is designed for long-term operation with a 100,000 hour L70 lifespan.

Installation and Long-Term Use

The fixture is designed for chain-cable mounting, which is standard for linear high bays in industrial settings. No cord is supplied with the fixture, so field wiring is required during installation.

The die-cast aluminum housing provides durability and heat dissipation. The fixture weight is 11 pounds, which is manageable for overhead installation by a two-person crew.

Operating temperature range supports installation in both cold storage and high-heat environments. The frosted lens reduces glare and improves visual comfort for personnel working below the fixture.

Long-term maintenance is minimized by the 100,000 hour rated life. The fixture is covered by a 5-year warranty from LED Lighting Supply.

How This Fixture Is Commonly Used

After installation, the adjustable wattage feature allows you to set the fixture output to match the lighting needs of each area. This is useful for balancing energy use and light levels as facility requirements change.

The color temperature adjustment lets you select between a neutral or cool white appearance, depending on the visual tasks or preferences in the space. This can be set during commissioning or as part of a lighting upgrade.

0-10V dimming can be used to reduce light levels during periods of low occupancy or to integrate with daylight harvesting systems. The fixture can be paired with a motion sensor for occupancy-based control if desired.

Routine operation does not require user intervention. The frosted lens helps maintain visual comfort for staff working under the lights, especially in areas with reflective surfaces or high activity.
