240 Watt LED UFO High Bay | 36000 Lumens | 5000K | 277-480V

Product Overview

The 240 Watt LED UFO High Bay delivers 36,000 lumens at 5000K, designed for high-ceiling commercial and industrial interiors. This fixture is intended for mounting heights typically ranging from 25 to 40 feet, providing a direct replacement for 1000W metal halide high bays. The compact UFO form factor allows for efficient installation in open areas where robust, high-output lighting is required.

It operates on 277-480V, supporting a wide range of facility electrical systems. The fixture is suitable for demanding environments such as warehouses, manufacturing plants, and distribution centers, where consistent, high-output illumination is critical for safety and productivity.

Core Performance and Output

This fixture outputs 36,000 lumens at 240 watts, achieving 150 lumens per watt. The 120° beam angle provides broad, uniform coverage suitable for open floor layouts and large interior spaces. Color temperature is 5000K, supporting high-visibility tasks and accurate color rendering with a CRI of 80+.

0-10V dimming is standard, allowing for integration with lighting controls and occupancy sensors. At mounting heights below 20 feet, output may be excessive and increase glare. At heights above 40 feet, uniformity and target light levels may decrease without careful layout planning.

Adjustability and Control Options

The fixture supports 0-10V dimming for integration with building lighting control systems. An optional motion sensor is available for occupancy-based control, supporting energy savings in intermittently used spaces. The wide beam angle is fixed, with no field-adjustable optics.

Standard mounting options include hook and pendant. Surface mounting is available as an accessory, providing flexibility for different ceiling structures. No tilt or aiming adjustment is provided; the fixture is designed for direct downward illumination.

Longevity and Reliability

L70 rated life is 50,000 hours, supporting long-term operation in commercial and industrial environments. The fixture includes a 5-year warranty. Die-cast aluminum housing and polycarbonate lens provide impact resistance and thermal management.

IP65 and IK10 ratings protect against dust, water jets, and mechanical impact. Surge protection is rated at 4kV, supporting reliability in facilities with variable power quality. Operating temperature range is -40°F to 113°F, suitable for most indoor environments.

Build Quality and Physical Characteristics

The fixture housing is die-cast aluminum with a black finish. The polycarbonate lens is impact-resistant and designed for high-bay environments. Dimensions are 12.8 inches wide by 9.1 inches high, with a total weight of 8 lbs.

Standard cord length is 5 feet, with an 8-inch dimming cord for control wiring. The fixture is UL and DLC Premium listed. All mounting hardware is designed for secure installation in high-ceiling applications.

Where This Product Fits Best

This 240W UFO high bay is suited for large, open indoor spaces with high ceilings and demanding light level requirements. It is commonly installed in environments where durability, high output, and broad coverage are required for safety and operational efficiency.

• warehouse lighting
• manufacturing facility lighting
• distribution center lighting
• gymnasium lighting
• aircraft hangar lighting
• basketball court lighting
• indoor sports facility lighting
• pole barn lighting

IP65 and IK10 ratings support use in dusty or damp locations and areas with potential for mechanical impact. The fixture is not intended for low-ceiling spaces or environments requiring specialized optics or hazardous location ratings.

Installation and Long-Term Use

Standard installation is by hook or pendant mount to structural ceiling members. Surface mounting is available for flat ceilings or where pendant/hook mounting is not feasible. The fixture?s 8 lb weight and compact size simplify handling at height.

5-foot cord supports connection to overhead power drops. 0-10V dimming and motion sensor wiring require additional low-voltage runs if controls are used. Routine cleaning of the lens and housing is recommended in dusty environments to maintain output.

Long-term maintenance is minimal due to solid-state design. No lamp or ballast replacements are required. Ensure mounting hardware remains secure during periodic facility inspections.

How This Fixture Is Commonly Used

Typical mounting heights range from 25 to 40 feet, with fixture spacing determined by target light levels and layout. In open warehouse or manufacturing areas, fixtures are often spaced 15 to 25 feet apart in a grid pattern. For sports or gymnasium applications, layout may be adjusted to minimize glare and maximize uniformity.

Higher output allows for wider spacing and reduced fixture count, but may increase glare if installed too low or without shielding. Motion sensors are used in areas with intermittent occupancy to reduce energy use.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. IP65 and IK10 ratings are standard. Surge protection is rated at 4kV. The fixture is covered by a 5-year warranty from the date of installation.

All electrical connections must comply with local codes and be performed by qualified personnel. The fixture is suitable for use in dry, damp, and dusty indoor environments. Not rated for hazardous locations or continuous submersion.
