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

Product Overview

This is a 270 / 340 / 400 Wattage Adjustable High Bay Linear LED fixture designed for high ceiling commercial and industrial interiors. It delivers selectable output from 41,600 to 56,100 lumens and offers both 4000K and 5000K color temperature settings. The fixture is intended for use in large open spaces and aisle environments where uniform, high-output lighting is required. Typical mounting heights range from 25 to 45 feet, making it suitable for warehouse aisles, manufacturing floors, and distribution centers.

The fixture is built for demanding environments that require reliable, efficient lighting with flexible installation options. It is commonly used as a direct replacement for 1000W to 2000W metal halide or T5HO linear fluorescent high bays in retrofit and new construction projects.

Core Performance and Output

This linear high bay provides three selectable wattage settings?270W, 340W, and 400W?delivering up to 56,100 lumens at a maximum efficacy of 150 lumens per watt. The 90° beam angle and polycarbonate lens produce a wide, uniform distribution suitable for both open areas and aisle layouts. Color temperature can be set to either 4000K or 5000K to match facility requirements.

0-10V dimming is standard, supporting integration with lighting controls and occupancy sensors. Power factor is 0.98 with THD below 20%. At lower mounting heights (below 20 feet), output may be excessive and require dimming or increased spacing to manage glare and uniformity. At mounting heights above 45 feet, uniformity may decrease without careful layout planning.

Adjustability and Control Options

Wattage and color temperature are field adjustable via onboard switches, allowing tuning of output and appearance during installation or future reconfiguration. This supports changes in facility use or lighting requirements without fixture replacement. The fixture supports 0-10V dimming for integration with advanced lighting controls, daylight harvesting, or occupancy-based systems.

Multiple mounting options?chain-cable (standard), pendant, or surface?allow adaptation to different ceiling structures and retrofit conditions. No cord is supplied; field wiring is required.

Longevity and Reliability

Rated for 70,000 hours of L70 life, this fixture is designed for long-term operation in demanding environments. The LED driver and light engine are thermally managed for consistent performance across the full wattage range. The fixture operates reliably in ambient temperatures from -4°F to 122°F.

Maintenance requirements are minimal compared to legacy HID or fluorescent systems. The polycarbonate lens and sealed housing reduce dust ingress and simplify cleaning in industrial settings.

Build Quality and Physical Characteristics

The housing is constructed from galvanized rolled iron for durability and corrosion resistance. The fixture measures 44.2 inches long by 10.2 inches wide and 1.8 inches high, with a total weight of 10 lbs. The white finish provides a clean appearance in commercial interiors.

All mounting hardware is compatible with standard chain-cable, pendant, or surface installations. The fixture is designed for direct hardwiring; no power cord is included. The polycarbonate lens is impact resistant and suitable for environments with moderate vibration or incidental contact.

Where This Product Fits Best

This linear high bay is intended for large, high-ceiling environments where high-output, uniform lighting is required. It is most commonly installed in:

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

The fixture is suitable for dry, indoor locations with ambient temperatures between -4°F and 122°F. It is not rated for wet or corrosive environments. The form factor and output are optimized for open areas and aisles with mounting heights from 25 to 45 feet.

Installation and Long-Term Use

Chain-cable mounting is standard and supports installation on open trusses or solid ceilings. Pendant and surface mounting options are available for facilities with specific structural requirements. The fixture is designed for direct connection to 100-277V circuits and supports both new construction and retrofit projects.

Routine maintenance is limited to occasional lens cleaning and inspection of mounting hardware. Field adjustability of wattage and color temperature allows adaptation to changes in facility layout or lighting needs without fixture replacement. The fixture?s low profile and light weight simplify handling during installation.

How This Fixture Is Commonly Used

Typical mounting heights range from 25 to 45 feet, with fixture spacing determined by required light levels and aisle width. In warehouse aisles, fixtures are often installed in continuous rows to provide uniform vertical and horizontal illumination. In open manufacturing or distribution spaces, grid or staggered layouts are used to balance coverage and minimize shadowing.

Higher output settings reduce the total fixture count but may require increased spacing or dimming to control glare. Adjustability supports tuning after installation to match operational needs or changes in racking and equipment layout.

Safety, Certifications, and Warranty

This fixture is UL listed and meets all relevant safety standards for commercial and industrial lighting. It is eligible for utility rebate programs where applicable. The product is covered by a 5-year warranty from the date of installation.

All components are rated for continuous operation within the specified temperature range. The fixture is suitable for use in code-compliant commercial and industrial facilities.
