240 / 270 / 310 Wattage Adjustable Linear LED High Bay | 36000 to 46500 Lumens | 4000K / 5000K Color Adjustable | 100-277V or 277-480V | 1 Foot 9 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 36,000 to 46,500 lumens and operates at 240, 270, or 310 watts. Typical installations include warehouse aisles, manufacturing lines, and distribution centers with mounting heights from 20 to 40 feet. The fixture supports chain-cable, pendant, or surface mounting for flexible deployment in new construction or retrofit projects.

Color temperature can be set to either 4000K or 5000K to match facility requirements. The fixture is UL listed and DLC Premium qualified for performance and efficiency. It is suitable for continuous operation in demanding environments where high output and reliability are required.

Core Performance and Output

This linear high bay provides three selectable wattage settings: 240W, 270W, and 310W, with corresponding lumen outputs of 36,000, 40,500, and 46,500 lumens. Delivered efficacy is 150 lumens per watt. The 90° beam angle and polycarbonate lens provide focused aisle illumination and minimize spill light into adjacent areas. 0-10V dimming is standard for integration with lighting controls.

Fixture is available in both 100-277V and 277-480V models. Output is suitable for mounting heights from 20 to 40 feet. At lower mounting heights, output may be excessive and require dimming or increased spacing to avoid glare. Uniformity may decrease at mounting heights above 40 feet without supplemental fixtures or careful layout.

Adjustability and Control Options

Wattage and color temperature are field adjustable, allowing tuning of light levels and appearance after installation. The fixture supports both 4000K and 5000K operation. 0-10V dimming is included for integration with occupancy sensors, daylight harvesting, or manual controls.

An optional motion sensor is available for occupancy-based control. Default sensor settings include 100% detection area, 30-second hold time, 60-second standby period, and 10% standby dimming. A remote control is required to change sensor settings and is supplied per project as needed. Emergency backup battery is available for code-required egress lighting.

Longevity and Reliability

L70 rated life is 50,000 hours. The fixture uses a die-cast aluminum housing for thermal management and durability. Surge protection is rated at 10kV for protection against electrical disturbances. Operating temperature range is -40°F to 122°F, supporting use in unconditioned or temperature-variable spaces.

All components are selected for continuous commercial operation. Polycarbonate lens resists impact and yellowing. The fixture is designed for minimal maintenance over its service life.

Build Quality and Physical Characteristics

The fixture measures 20.5 inches long by 11.54 inches wide and 2.13 inches high, with a total weight of 10 lbs. Housing is die-cast aluminum with a white finish. The lens is polycarbonate for impact resistance and optical clarity. No cord is supplied; wiring is completed on site.

Mounting options include chain-cable (standard), pendant, or surface mounting. The fixture is designed for direct replacement of 1000W metal halide or similar legacy high bay fixtures in linear form factor applications.

Where This Product Fits Best

This linear high bay is intended for high ceiling commercial and industrial interiors requiring high output, uniform aisle or open area illumination, and flexible mounting. It is commonly deployed in:

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

Suitable for dry and damp locations. Not intended for environments with corrosive chemicals, direct water exposure, or hazardous locations. Performance is stable across a wide temperature range.

Installation and Long-Term Use

Chain-cable mounting is standard and supports rapid installation in retrofit or new construction. Pendant and surface mounting options are available for integration with existing infrastructure. The fixture is designed for direct replacement of legacy linear high bays, minimizing changes to layout or wiring.

Wattage and color temperature can be set during commissioning or adjusted later as needs change. Maintenance is limited to periodic cleaning and inspection. Emergency backup and motion sensor options support code compliance and energy management.

How This Fixture Is Commonly Used

Typical mounting heights range from 20 to 40 feet, with fixture spacing determined by required light levels and aisle width. In warehouse aisles, fixtures are often installed in continuous rows or staggered patterns to maximize uniformity. In open manufacturing or distribution areas, grid or linear layouts are common.

Higher output settings reduce fixture count but may increase glare if not spaced appropriately. Dimming and sensor integration are used to manage energy use and occupant comfort. Layouts should be reviewed for uniformity and compliance with facility lighting standards.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. Surge protection is rated at 10kV. Power factor is 0.90 minimum, with total harmonic distortion below 20%. The fixture is covered by a 5-year warranty from date of installation.

All components are rated for commercial and industrial use. Emergency backup and motion sensor options are available for code compliance and energy management.
