240 / 270 / 310 Watt Adjustable LED UFO High Bay | 34800 to 45000 Lumens | 4000K / 5000K Adjustable | 100-277V

Product Overview

This 2-foot linear LED high bay delivers 19,500 to 24,750 lumens across three selectable wattage settings: 130W, 140W, or 165W. At 150 lumens per watt, it serves as a direct replacement for 400-watt metal halide fixtures in warehouse, manufacturing, and distribution environments.

Field-adjustable color temperature allows selection between 4000K and 5000K to match existing lighting or specific task requirements. The fixture operates on 100-277V input and includes 0-10V dimming capability for integration with building lighting controls.

Die-cast aluminum construction supports an L70 rated lifespan of 100,000 hours. The fixture includes 6kV surge protection and operates across a wide ambient temperature range from -40°F to 113°F.

Where This Product Fits Best

This fixture suits high-ceiling commercial and industrial spaces where 400-watt metal halide fixtures are currently installed or specified. The 120-degree beam angle with frosted lens optics provides broad, diffused coverage appropriate for general area illumination in open floor plans.

The operating temperature range accommodates unconditioned spaces including cold storage entries, loading docks, and facilities without climate control. Chain or cable mounting is standard, making this fixture appropriate for suspended ceiling applications at typical high bay mounting heights.

Voltage compatibility across 100-277V at 50/60Hz supports standard commercial electrical systems. The 0-10V dimming input allows connection to compatible building automation or dimming controls where present.

Performance and Functional Considerations

Lumen output scales with wattage selection: 19,500 lumens at 130W, 21,000 lumens at 140W, and 24,750 lumens at 165W. This range allows adjustment based on mounting height, spacing, and required light levels without changing fixtures.

CRI of 80+ supports visual tasks where accurate color rendering matters, including quality inspection, inventory identification, and general material handling. The frosted lens reduces glare and harsh shadows common with clear optic high bays.

Power factor of 0.90 and THD under 20% meet typical commercial electrical requirements. The 6kV surge protection rating provides resilience against transient voltage events common in industrial electrical environments.

Installation and Long-Term Use

The fixture measures 23.2 x 12.6 x 3 inches and weighs 6.75 pounds. No power cord is included; direct wiring is required. Chain or cable mounting hardware supports suspended installation from structure or ceiling supports.

Wattage and color temperature adjustments are made at the fixture. Once set, these configurations remain fixed until manually changed. The white fixture housing blends with standard commercial ceiling environments.

At 100,000 hours L70 rated life, this fixture supports extended service intervals. The operating temperature range from -40°F to 113°F allows installation in spaces with significant ambient temperature variation across seasons.

How This Fixture Is Commonly Used

In day-to-day operation, this fixture runs at the wattage and color temperature selected during installation. Most facilities set these once based on light level requirements and leave them unchanged unless layout or use changes significantly.

Where 0-10V dimming controls are connected, the fixture responds to external signals for scheduled dimming, daylight harvesting, or occupancy-based reduction. Without external controls, the fixture operates at full output for the selected wattage setting.

A motion sensor is available as an option. If installed, a separate remote control is required to adjust sensor settings from their defaults.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The 5-year warranty is provided by LED Lighting Supply.

The fixture includes 6kV surge protection. Operating temperature range is rated from -40°F to 113°F.
