180 / 240 / 300 Watt Adjustable LED Indirect High Bay Light | 25200 to 42000 Lumens | 4000K / 5000K | 100-277V | 3 Foot

Product Overview

This is a 3-foot linear LED indirect high bay fixture with selectable wattage and color temperature. It is designed for high ceiling commercial and industrial interiors requiring uniform, glare-controlled illumination. Typical installations include warehouse aisles, manufacturing lines, and distribution center racking areas with mounting heights from 18 to 40 feet.

The fixture supports chain-cable suspension and includes a 3-foot mounting kit. It is intended as a direct replacement for 250W or 400W metal halide high bays, offering improved efficiency and reduced maintenance in demanding environments.

Core Performance and Output

This linear high bay delivers selectable output at 180W, 240W, or 300W, producing 25,200 to 42,000 lumens at 140 lumens per watt. The indirect optical design and frosted polycarbonate lens provide a 90° beam angle for controlled aisle and open area coverage. Color temperature is field adjustable between 4000K and 5000K.

0-10V dimming is standard for integration with lighting controls. Output is suitable for mounting heights from 18 to 40 feet. Excessive output may cause glare at lower mounting heights or in low-density layouts. Uniformity may decrease if spacing exceeds recommended patterns for the selected wattage.

Adjustability and Control Options

Wattage and color temperature are both adjustable via onboard switches, allowing field selection to match application requirements or energy targets. The lens can be rotated 180° for directional control, supporting both indirect and direct/indirect lighting strategies.

0-10V dimming enables integration with occupancy sensors, daylight harvesting, or building management systems. No onboard motion or daylight sensor is included; external controls must be specified separately.

Longevity and Reliability

The fixture is rated for 150,000 hours (L70) at ambient temperatures from -22°F to 122°F. The LED driver and light engine are thermally managed for continuous operation in high bay environments.

All components are designed for long-term reliability in commercial and industrial settings. Routine cleaning of the lens and housing is recommended to maintain optical performance over time.

Build Quality and Physical Characteristics

The housing is constructed from durable materials with a white finish and measures 35.4 inches long by 11.5 inches wide by 2 inches high. The fixture weighs 7.3 lbs and is designed for chain-cable suspension only. No power cord is included; field wiring is required.

The frosted polycarbonate lens provides impact resistance and diffuses light for visual comfort. The fixture is ETL and DLC Premium certified. All hardware is suitable for typical warehouse and manufacturing environments.

Where This Product Fits Best

This linear high bay is intended for high ceiling interiors where uniform, efficient 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

Suitable for dry and damp locations with ambient temperatures from -22°F to 122°F. Not intended for wet locations or environments with corrosive airborne contaminants.

Installation and Long-Term Use

Chain-cable suspension is required for mounting. The included 3-foot suspension kit supports typical high bay installation patterns. Field wiring is necessary; no cord is supplied. The fixture is compatible with standard 100-277V circuits at 50/60 Hz.

Routine inspection of suspension hardware and periodic cleaning of the lens are recommended for long-term performance. The adjustable wattage and color temperature allow adaptation to changing facility requirements without fixture replacement.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 40 feet, depending on output setting and target light levels. Fixtures are spaced based on aisle width, racking layout, and required uniformity. Linear high bays are often installed in rows parallel to aisles or production lines for consistent coverage.

Higher output settings reduce fixture count but may increase glare if used at lower mounting heights or in open areas without racking. Spacing and layout should be confirmed based on photometric calculations for the specific environment.

Safety, Certifications, and Warranty

This fixture is ETL listed and DLC Premium certified. It meets all relevant safety and performance standards for commercial and industrial lighting. The product is covered by a 5-year warranty from the date of installation.

All installation and maintenance must comply with local electrical codes and facility safety protocols. Only qualified personnel should perform wiring and suspension work.
