230 / 260 / 300 Watt Adjustable Linear LED High Bay | 34500 to 45000 Lumens | 4000K / 5000K Adjustable | 100-277V or 277-480V | 3 Foot 8 Inches

Product Overview

This is a 230 / 260 / 300 Watt Adjustable Linear LED High Bay designed for high ceiling industrial and commercial interiors. The fixture delivers up to 45,000 lumens with selectable wattage and color temperature, supporting both 100-277V and 277-480V input. Typical use includes mounting heights from 25 to 40 feet in warehouse aisles, manufacturing lines, and distribution centers where uniform, high-output lighting is required.

The linear form factor and chain-cable mounting allow for direct replacement of legacy linear fluorescent or metal halide high bays. This model is suitable for environments where flexibility in output and color temperature is needed for changing operational requirements.

Core Performance and Output

This fixture provides selectable output at 230W, 260W, or 300W, producing 34,500 to 45,000 lumens at 150 lumens per watt. The 120° beam angle and frosted lens deliver wide, even coverage for open areas and aisles. Color temperature can be set to either 4000K or 5000K to match task or ambient needs.

0-10V dimming is standard, supporting integration with lighting controls or occupancy sensors. At lower mounting heights below 20 feet, output may be excessive and require dimming or increased fixture spacing to avoid glare. Uniformity may decrease at mounting heights above 40 feet due to beam spread limitations.

Adjustability and Control Options

Wattage and color temperature are field adjustable, allowing adaptation to changing lighting requirements without fixture replacement. The integrated motion sensor supports occupancy-based control, with default settings for detection area, hold time, and standby dimming. Sensor adjustments require a remote control (one per project).

0-10V dimming enables further control through building automation or manual dimmers. The fixture supports both standard and high voltage input ranges, simplifying deployment across different electrical systems.

Longevity and Reliability

The fixture is rated for 100,000 hours (L70), supporting long-term operation in demanding environments. The die-cast aluminum housing and 6kV surge protection provide durability against electrical disturbances and physical impacts.

Operating temperature range is -40°F to 113°F, covering most indoor industrial and commercial conditions. The fixture is UL listed and DLC Premium qualified. A 5-year warranty is provided by the manufacturer.

Build Quality and Physical Characteristics

The housing is constructed from die-cast aluminum with a white finish. The fixture measures 44.3 inches long, 12.6 inches wide, and 3 inches high, weighing 11 pounds. Chain-cable mounting is standard, supporting secure installation to trusses or ceiling structures.

The frosted lens reduces glare and diffuses light for visual comfort. No power cord is included; wiring is completed on site. The fixture is designed for high bay mounting patterns and supports standard 50/60 Hz operation.

Where This Product Fits Best

This linear high bay is intended for large, high-ceiling indoor spaces requiring high-output, uniform lighting. It is most commonly used 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 between 25 and 40 feet, where flexibility in output and color temperature is needed, are best suited for this fixture. The fixture is not intended for wet locations or environments with corrosive atmospheres.

Installation and Long-Term Use

Chain-cable mounting supports direct suspension from ceiling structures or trusses. The fixture?s weight and dimensions allow for single-person handling in most cases. Field adjustability for wattage and color temperature reduces the need for fixture changes during layout modifications.

Motion sensor settings can be adjusted with a remote control. Routine maintenance is limited to occasional cleaning of the lens and housing. The fixture?s long lifespan and surge protection minimize service interruptions in demanding environments.

How This Fixture Is Commonly Used

Fixtures are typically installed in rows along warehouse aisles or above production lines, spaced 12 to 20 feet apart depending on mounting height and required light levels. Mounting heights from 25 to 40 feet are standard for this output range.

Higher output settings reduce the number of fixtures needed but may increase glare if not properly spaced or dimmed. Layouts are often adjusted to balance uniformity, energy use, and visual comfort based on operational needs.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. Surge protection is rated at 6kV. The product is covered by a 5-year manufacturer warranty. All components are rated for indoor use in dry environments within the specified temperature range.

Standard safety practices for high bay installation and maintenance apply. The fixture supports both standard and high voltage operation, with a power factor of 0.90 and THD below 20%.
