170 Watt LED High Bay Linear | 23120 Lumens | 4000K / 5000K Adjustable | 277-480V | 2 Foot

Product Overview

This 170 Watt LED High Bay Linear fixture is designed for high ceiling commercial and industrial interiors requiring efficient, uniform illumination. It delivers 23,120 lumens with selectable 4000K or 5000K color temperature, supporting both general and task lighting needs. Typical installations include warehouse aisles, manufacturing lines, and distribution center racking, where consistent light levels and reliable operation are required at mounting heights from 15 to 30 feet.

The fixture is built for 277-480V operation and replaces 400W metal halide systems. It supports chain-cable, pendant, or surface mounting, allowing flexibility for retrofit or new construction projects. The 2-foot linear form factor fits well in racked aisles and open bays where directional control and spacing are critical.

Core Performance and Output

This fixture outputs 23,120 lumens at 170 watts, providing an efficacy of 136 lumens per watt. The 110° beam angle delivers wide, even coverage suitable for open areas and aisle layouts. Color temperature is field adjustable between 4000K and 5000K to match visual requirements or existing site standards. 0-10V dimming is standard for integration with lighting controls or energy management systems.

Uniformity is maintained at typical mounting heights up to 30 feet. At lower heights, output may be excessive for low-activity areas and may require dimming or increased spacing to avoid glare. The fixture is not intended for mounting above 35 feet, where coverage and uniformity may decrease.

Adjustability and Control Options

Color temperature can be set to either 4000K or 5000K via onboard adjustment, supporting both neutral and daylight visual environments. 0-10V dimming is included for compatibility with standard dimming systems and occupancy or daylight sensors. No onboard motion or daylight sensor is included; external controls can be integrated as needed.

Beam distribution is fixed at 110°, with polycarbonate or frosted lens options to manage glare and diffusion. No field-adjustable optics are available for this model.

Longevity and Reliability

The fixture is rated for 70,000 hours of L70 life, supporting long-term operation in demanding environments. The power factor is 0.98, and total harmonic distortion is limited to 20% maximum, ensuring stable electrical performance on 277-480V circuits. Operating temperature range is -4°F to 113°F, suitable for most conditioned and unconditioned interiors.

All components are selected for durability and consistent output over time. No user-serviceable parts are included; replacement is recommended at end of life.

Build Quality and Physical Characteristics

The housing is constructed from galvanized rolled iron for structural rigidity and corrosion resistance. The fixture measures 24.8 inches long by 15.2 inches wide and 2.2 inches high, with a total weight of 10 lbs. Lens options include polycarbonate or frosted for impact resistance and glare control.

Standard finish is white. No cord is supplied; field wiring is required. Mounting hardware supports chain-cable, pendant, or surface installation. The fixture is UL listed and rebate eligible.

Where This Product Fits Best

This linear high bay is intended for high ceiling commercial and industrial interiors where uniform, efficient lighting is required. It is most often installed in:

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

Environments with open bays, racked aisles, or large storage areas benefit from the wide beam and high output. The fixture is suitable for both new construction and retrofit projects where 277-480V power is available and mounting heights are within the recommended range.

Installation and Long-Term Use

Chain-cable mounting is standard, with pendant and surface options available for different ceiling types or retrofit conditions. The fixture is designed for direct hardwiring; no cord is included. Installation is straightforward for experienced personnel familiar with high bay layouts and 277-480V circuits.

Routine cleaning of the lens and housing is recommended to maintain output. No scheduled maintenance is required beyond periodic inspection. The fixture is not intended for wet locations or environments with corrosive airborne contaminants.

How This Fixture Is Commonly Used

Typical mounting heights range from 15 to 30 feet, with fixture spacing determined by required light levels and aisle width. In racked aisles, fixtures are often aligned parallel to shelving for optimal vertical illumination. Open areas may use grid or staggered layouts for uniform coverage.

Higher output allows for wider spacing and reduced fixture count, but may increase glare if installed below 15 feet or in visually sensitive areas. Dimming controls can be used to fine-tune light levels as needed.

Safety, Certifications, and Warranty

This fixture is UL listed and meets all relevant safety standards for commercial and industrial interior lighting. It is eligible for utility rebates where applicable. The product includes a 5-year warranty covering manufacturing defects and performance.

No additional safety features are included beyond standard electrical and mechanical protections. Installation must comply with local codes and site safety requirements.
