480 Watt LED UFO High Bay | 76800 Lumens | 5000K | 100-277V

Product Overview

The 480 Watt LED UFO High Bay delivers 76,800 lumens at 5000K, designed for high-ceiling commercial and industrial interiors requiring maximum light output. This fixture is built for large-scale spaces where legacy 1500W metal halide units are being replaced or upgraded. Typical mounting heights range from 30 to 50 feet, supporting applications such as warehouses, manufacturing plants, and gymnasiums.

The fixture features a robust die-cast aluminum housing, polycarbonate lens, and a standard 60° beam angle for focused, high-intensity illumination. It operates on 100-277V input, supporting a wide range of facility electrical systems. Eye-hook mounting is standard, providing a secure and straightforward installation method for overhead structures.

Core Performance and Output

This high bay produces 76,800 lumens at 480 watts, achieving an efficacy of 160 lumens per watt. The 60° beam angle delivers concentrated light suitable for tall, open spaces, with optional 10° and 30° optics available for even tighter distribution. The fixture maintains a CRI of 70+, supporting general visibility and color recognition in industrial environments.

Electrical performance includes a power factor of 0.93 and maximum THD of 20%. The fixture is dimmable via 1-10V controls. At mounting heights below 25 feet, output may be excessive and increase glare. Uniformity can decrease at mounting heights above 50 feet without careful layout and optic selection.

Adjustability and Control Options

Standard 1-10V dimming is supported, allowing integration with compatible dimming systems for energy management or task tuning. The fixture is available with 60° beam angle as standard, with optional 10° and 30° optics for applications requiring more focused light distribution.

No onboard motion or daylight sensors are included. Controls integration is limited to external dimming systems. The fixture is not field-adjustable for color temperature or wattage.

Longevity and Reliability

L70 rated life is 244,000 hours, supporting long-term operation in demanding environments. The fixture is UL listed and DLC Premium qualified, with a 5-year warranty covering manufacturing defects and performance.

IP66 and IK08 ratings provide protection against dust, water ingress, and moderate impact. Integrated 4kV surge protection is included for electrical reliability in facilities with variable power quality.

Build Quality and Physical Characteristics

The fixture uses a die-cast aluminum housing for thermal management and durability. The polycarbonate lens resists impact and chemical exposure common in industrial settings. The fixture measures 17.7 inches in diameter and 9.5 inches in height, with a total weight of 24 lbs.

Standard mounting is via eye-hook, compatible with most overhead structures. The fixture is finished in black and includes a 5-foot power cord and 8-inch dimming cord for straightforward installation.

Where This Product Fits Best

This fixture is designed for large, high-ceiling indoor environments requiring high-output, focused illumination. It is suitable for both new construction and retrofit projects replacing high-wattage HID fixtures. The fixture?s optical options and robust construction support use in demanding commercial and industrial interiors.

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

IP66 and IK08 ratings allow use in dusty or damp environments and areas with moderate risk of impact. The fixture is not suitable for low ceilings or environments requiring NSF or food-grade certification.

Installation and Long-Term Use

Eye-hook mounting supports direct suspension from structural beams or trusses. The fixture?s weight and size require secure mounting points and may need two-person handling during installation. The 5-foot cord provides flexibility for connection to overhead power drops.

Routine maintenance is minimal due to the sealed housing and long LED life. Periodic inspection of mounting hardware and electrical connections is recommended, especially in high-vibration or dusty environments. The fixture?s design supports straightforward replacement if required.

How This Fixture Is Commonly Used

Typical mounting heights range from 30 to 50 feet, with fixture spacing determined by required light levels and beam angle selection. In open warehouse or gymnasium layouts, fixtures are often spaced 20 to 30 feet apart for uniform coverage. Aircraft hangars and convention centers may require wider spacing or tighter optics for specific tasks.

Higher output reduces the total fixture count but may increase glare if installed too low or without proper optics. Layouts should consider both horizontal and vertical illumination requirements for the intended activity.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. It carries an IP66 rating for water and dust ingress and an IK08 impact rating. Integrated 4kV surge protection is included. The product is covered by a 5-year warranty.

All certifications and ratings are documented for code compliance and facility standards. No additional safety accessories are required for standard installations.
