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

Product Overview

This is an adjustable wattage LED UFO high bay designed for high-ceiling commercial and industrial interiors. Output can be set to 240, 270, or 310 watts, supporting a range of mounting heights and light level requirements. Typical installations include warehouse, manufacturing, and distribution center environments where legacy 400W or 1000W metal halide fixtures are being replaced.

The fixture supports both 4000K and 5000K color temperatures, selectable at installation. It is suitable for open floor layouts, sports facilities, and large-volume spaces requiring robust, uniform illumination. The housing is sealed to IP65 and rated IK10 for impact resistance, supporting use in demanding environments.

Core Performance and Output

This UFO high bay delivers 34,800 to 45,000 lumens depending on wattage setting, with an efficacy of 145 lumens per watt. The 110° beam angle provides wide, even coverage for open areas and high ceilings. Output levels are appropriate for mounting heights from 20 to 40 feet, supporting both general and task lighting in large spaces.

Color temperature can be set to 4000K or 5000K. 0-10V dimming is standard for integration with lighting controls. At lower mounting heights, output may be excessive and require dimming or increased spacing to control glare. At mounting heights above 40 feet, uniformity may decrease without supplemental fixtures or tighter spacing.

Adjustability and Control Options

Wattage and color temperature are field adjustable, allowing tuning for specific light levels and visual comfort. This supports changes in facility layout or usage without fixture replacement. The fixture is compatible with 0-10V dimming systems for occupancy or daylight control.

An optional motion sensor is available for automated control. Adjustability features are accessible at the fixture, supporting commissioning and future reconfiguration.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) at typical operating conditions. The die-cast aluminum housing and polycarbonate lens provide durability in industrial settings. IK10 impact rating and 4kV surge protection support long-term reliability in areas with equipment movement or electrical disturbances.

Operating temperature range is -40°F to 113°F, suitable for unconditioned warehouses and manufacturing spaces. The fixture is covered by a 5-year warranty.

Build Quality and Physical Characteristics

The fixture uses a die-cast aluminum body with a black finish and a polycarbonate lens. It measures 14 inches wide by 11 inches high and weighs 11 pounds. The housing is sealed to IP65 for dust and water ingress protection, supporting use in damp or dusty environments.

Mounting options include hook, pendant, or surface mounting. Standard cord length is 5 feet, with an 8-inch dimming cord. The fixture is UL listed and DLC Premium qualified.

Where This Product Fits Best

This UFO high bay is designed for large, high-ceiling interiors requiring robust, uniform lighting. It is commonly installed in:

• warehouse lighting
• manufacturing facility lighting
• distribution center lighting
• gymnasium lighting
• aircraft hangar lighting
• basketball court lighting
• indoor sports facility lighting
• metal building lighting

Environmental characteristics include resistance to dust, water spray, and impact. The fixture is suitable for both conditioned and unconditioned spaces with mounting heights from 20 to 40 feet.

Installation and Long-Term Use

Mounting options support hook, pendant, or surface installation on standard industrial structures. The fixture’s weight and dimensions are compatible with most truss, purlin, or unistrut mounting systems. Field adjustability for wattage and color temperature allows tuning during commissioning or future layout changes.

Routine maintenance is limited to periodic cleaning of the lens and housing. The sealed design reduces dust ingress and minimizes cleaning frequency. All wiring and adjustments are accessible at the fixture, supporting straightforward installation and service.

How This Fixture Is Commonly Used

Typical mounting heights range from 20 to 40 feet, with fixture spacing determined by output setting and required light levels. In open warehouse or manufacturing layouts, fixtures are often spaced 15 to 25 feet apart for uniform coverage. For sports or gymnasium applications, layout may be adjusted to minimize glare and optimize vertical illumination.

Higher output settings reduce fixture count but may require increased spacing or dimming to control brightness. Adjustability supports adaptation to changes in racking, equipment, or space use over time.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. It is rated IP65 for water and dust ingress and IK10 for impact resistance. Surge protection is rated at 4kV. The product is covered by a 5-year warranty from the date of installation.

All safety and certification markings are present on the fixture label. Installation must comply with local electrical codes and mounting requirements for overhead lighting in commercial and industrial environments.
