155 / 180 / 210 Wattage Adjustable High Bay Linear | 22880 to 31000 Lumens | 4000K / 5000K Adjustable | 100-277V or 277-480V | 1 Foot 2 Inches

Product Overview

This is a wattage and color adjustable linear LED high bay designed for high ceiling commercial and industrial interiors. The fixture delivers selectable output from 22,880 to 31,000 lumens and operates at 155, 180, or 210 watts. Typical installations include warehouse aisles, manufacturing lines, and distribution center racking with mounting heights from 18 to 35 feet. The compact 14-inch by 11.5-inch form factor supports chain-cable, pendant, or surface mounting in new or retrofit projects.

Selectable 4000K or 5000K CCT and dual voltage drivers (100-277V or 277-480V) allow adaptation to a range of lighting requirements and electrical systems. The fixture is UL listed and DLC Premium qualified for use in regulated environments.

Core Performance and Output

This linear high bay provides three selectable output levels: 22,880, 26,570, or 31,000 lumens, with a maximum efficacy of 150 lumens per watt. The 90° polycarbonate lens delivers a wide, uniform beam suitable for open areas and aisle layouts. 0-10V dimming is standard for integration with lighting controls or occupancy sensors.

Output is appropriate for mounting heights between 18 and 35 feet. At lower mounting heights, the highest output setting may produce excessive brightness or glare. Uniformity may decrease if spacing exceeds recommended patterns for the selected wattage.

Adjustability and Control Options

Wattage and color temperature can be field-adjusted using onboard switches, allowing tuning for specific light levels or visual comfort. The fixture supports both 4000K and 5000K operation to match task or ambient requirements. 0-10V dimming is included for use with compatible controls.

Optional motion sensor and emergency backup battery are available. The motion sensor is preset for 100% detection area, 30-second hold time, and 10% standby dimming. Remote control is required to change sensor settings; one remote per project is recommended.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) and includes a 5-year warranty. Die-cast aluminum housing and polycarbonate lens provide impact resistance and thermal management. 10kV surge protection is standard for electrical reliability in industrial environments.

Operating temperature range is -40°F to 122°F, supporting use in unconditioned or temperature-variable spaces. Power factor is 0.90 and THD is 20% max, meeting commercial electrical standards.

Build Quality and Physical Characteristics

The fixture measures 14 inches long, 11.5 inches wide, and 2.1 inches high, with a total weight of 7 lbs. The housing is finished in white die-cast aluminum for corrosion resistance and durability. The polycarbonate lens is impact resistant and provides even light distribution.

Chain-cable mounting is standard, with pendant and surface mounting options available. No cord is supplied; field wiring is required. The fixture is designed for quick installation and minimal maintenance in high bay environments.

Where This Product Fits Best

This linear high bay is suited for high ceiling commercial and industrial interiors requiring efficient, uniform lighting. It is commonly installed in:

• warehouse aisle lighting
• manufacturing facility lighting
• distribution center lighting
• retail warehouse lighting
• storage facility lighting
• commercial interior high ceiling lighting

Environments with mounting heights from 18 to 35 feet, moderate to high ambient temperatures, and a need for flexible output or color temperature benefit from this fixture. The fixture is not intended for wet locations or environments with corrosive atmospheres.

Installation and Long-Term Use

Chain-cable mounting is standard and supports rapid installation in open ceilings or racking layouts. Pendant and surface mounting options are available for solid deck or finished ceilings. The fixture is compatible with both 100-277V and 277-480V electrical systems, supporting retrofit and new construction projects.

Routine maintenance is limited to periodic cleaning of the lens and inspection of wiring connections. Emergency backup and motion sensor options can be field-installed as needed. The fixture?s compact size and low weight simplify handling and overhead work.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 35 feet, with fixture spacing determined by output setting and required light levels. In warehouse aisles, fixtures are often spaced 12 to 20 feet apart along the run. In open manufacturing or storage areas, grid layouts are common for uniform coverage.

Higher output settings reduce fixture count but may increase glare if installed below 20 feet. Spacing and layout should be adjusted based on racking height, ceiling reflectance, and task requirements.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. It includes 10kV surge protection and is rated for operation from -40°F to 122°F. The product carries a 5-year warranty covering manufacturing defects and performance.

All electrical and mounting work should follow local codes and site safety procedures. Emergency backup and motion sensor accessories are available for code compliance and energy management.
