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

Product Overview

This 3-foot 8-inch linear LED high bay delivers selectable output from 34,500 to 45,000 lumens at 230, 260, or 300 watts. Field-adjustable wattage and color temperature allow configuration to match specific space requirements without fixture substitution. Output reaches 150 lumens per watt across all settings.

The fixture replaces 1000-watt metal halide systems and operates on 100-277V input at 50 or 60 Hz. Color temperature adjusts between 4000K and 5000K. A frosted lens distributes light across a 120-degree beam angle. CRI is 80 or higher.

Construction uses die-cast aluminum housing with a white finish. The fixture measures 44.3 by 12.6 by 3 inches and weighs 11 pounds. Chain or cable mounting is standard. No cord is included.

Where This Product Fits Best

This fixture is sized for high-ceiling industrial and commercial spaces where linear form factor and high output are required. The 1000-watt metal halide replacement class positions it for retrofit in warehouses, manufacturing bays, and distribution facilities running legacy HID systems.

Operating temperature range spans -40°F to 113°F, supporting installation in cold storage entries, loading docks, and unconditioned warehouse zones. The 100-277V input covers standard commercial and industrial service without transformer requirements.

The linear housing works well in aisle-oriented layouts or where fixtures need to align with structural bays and racking systems. At 11 pounds, chain or cable suspension handles the load without specialized hardware.

Performance and Functional Considerations

Three wattage settings produce distinct lumen outputs: 230 watts at 34,500 lumens, 260 watts at 39,000 lumens, and 300 watts at 45,000 lumens. Efficacy remains constant at 150 lumens per watt regardless of selected output. This allows adjustment based on mounting height or task requirements without efficiency loss.

Color temperature selection between 4000K and 5000K affects visual appearance. 4000K produces a neutral white suitable for general warehouse use. 5000K shifts cooler and may improve contrast in inspection or assembly areas. Both settings maintain 80+ CRI.

The fixture includes 0-10V dimming capability for integration with building management systems or manual dimmers. Power factor is 0.90 with total harmonic distortion at 20% maximum. Rated lifespan reaches 100,000 hours at L70.

Installation and Long-Term Use

Standard mounting uses chain or cable suspension. The fixture ships without a power cord, so field wiring is required. At 44.3 inches in length and 11 pounds, two-person handling during installation is practical but not always necessary depending on lift equipment.

Wattage and color temperature adjustments are made at the fixture. Once configured, settings remain fixed unless manually changed. The 6kV surge protection rating provides resilience against electrical transients common in industrial electrical environments.

Die-cast aluminum housing supports heat dissipation over the rated 100,000-hour lifespan. The operating temperature range of -40°F to 113°F accommodates seasonal temperature swings and facilities without climate control. A motion sensor is available and requires a remote control to adjust settings from factory defaults.

How This Fixture Is Commonly Used

Once installed, facility operators typically set the wattage based on ceiling height and desired light levels, then leave it. The three output levels let you tune brightness during commissioning rather than accepting a fixed output that might over-light or under-light the space.

Color temperature is usually selected during initial setup based on the type of work being done. Manufacturing and inspection areas often run at 5000K for sharper visual contrast. General storage and circulation spaces tend toward 4000K for a more neutral appearance.

The 0-10V dimming input allows the fixture to respond to external controls if the building uses an energy management system or occupancy-based dimming strategy. In facilities without centralized controls, the fixture operates at the selected wattage continuously.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The 6kV surge protection rating allows installation in environments with electrical noise from motors, compressors, and switching equipment.

We provide a 5-year warranty on this fixture.
