150 Watt LED UFO High Bay | 21700 Lumens | 5000K | 277-480V

Product Overview

This 150 Watt LED UFO High Bay is designed for high-ceiling commercial and industrial interiors requiring efficient, high-output illumination. It delivers 21,700 lumens at 5000K, supporting mounting heights typically found in warehouses, manufacturing plants, and distribution centers. The fixture operates on 277-480V, making it suitable for facilities with higher voltage electrical systems. It is a direct replacement for 400W to 1000W metal halide high bays, providing significant energy reduction and lower maintenance requirements.

The fixture features a compact, die-cast aluminum housing with a polycarbonate lens and is rated for use in demanding environments. It is UL and DLC Premium listed, IP65 and IK10 rated, and supports both hook and optional surface mounting. A motion sensor accessory is available for occupancy-based control.

Core Performance and Output

This fixture outputs 21,700 lumens at 150 watts, achieving 145 lumens per watt. The 120° beam angle provides wide, uniform coverage suitable for open floor layouts and large interior spaces. Color temperature is 5000K with a CRI above 80, supporting accurate color rendering in work environments. The fixture supports 0-10V dimming for integration with lighting controls.

Performance is optimized for mounting heights between 18 and 35 feet. At lower mounting heights, output may be excessive and increase glare. At heights above 35 feet, uniformity and light levels may decrease unless fixtures are spaced more closely. The fixture is designed for continuous operation in ambient temperatures from -40°F to 113°F.

Adjustability and Control Options

The fixture supports 0-10V dimming for integration with standard lighting control systems. An optional motion sensor is available for occupancy-based operation, allowing for energy savings in intermittently used spaces. The fixture can be installed with a standard hook mount or an optional surface mount kit, providing flexibility for different ceiling structures.

No field-adjustable wattage or CCT is provided. The fixture is compatible with most commercial dimming systems and can be grouped with other high bays for zone control. Sensor placement should be coordinated to avoid coverage gaps in large open areas.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) and includes a 5-year warranty. The die-cast aluminum housing and polycarbonate lens provide impact resistance (IK10) and protection against dust and water ingress (IP65). Surge protection is rated at 4kV, supporting stable operation in facilities with power fluctuations.

Maintenance requirements are minimal compared to legacy HID fixtures. The fixture is designed for continuous operation in demanding environments, including manufacturing and distribution spaces with elevated ambient temperatures and airborne particulates.

Build Quality and Physical Characteristics

The fixture measures 11.6 inches in diameter and 8.5 inches in height, with a total weight of 10 pounds. The housing is black die-cast aluminum with a polycarbonate lens. The fixture includes a 5-foot power cord and an 8-inch dimming cord for control wiring. Mounting is via hook as standard, with an optional surface mount kit available.

All components are sealed to IP65, supporting installation in areas exposed to dust and occasional water spray. The fixture is suitable for use in environments where impact resistance is required. The design supports both new construction and retrofit projects where legacy high bays are being replaced.

Where This Product Fits Best

This 150W LED UFO High Bay is suited for large, high-ceiling interiors requiring high-output, uniform lighting. It is commonly installed in commercial and industrial environments with mounting heights from 18 to 35 feet and where robust construction is needed.

• warehouse lighting
• manufacturing facility lighting
• distribution center lighting
• gymnasium lighting
• aircraft hangar lighting
• basketball court lighting
• pole barn lighting
• commercial shop lighting

The fixture is suitable for both new installations and retrofits in spaces with high ceilings, open layouts, and exposure to dust or occasional moisture. The IP65 and IK10 ratings support use in demanding environments where durability and ingress protection are required.

Installation and Long-Term Use

The fixture is designed for overhead mounting using the included hook or optional surface mount kit. Typical installation heights range from 18 to 35 feet, depending on required light levels and application. The 5-foot power cord supports flexible placement, and the fixture is compatible with 277-480V electrical systems.

Routine maintenance is limited to periodic cleaning of the lens and housing. The sealed design minimizes dust ingress and reduces the need for frequent servicing. When using the motion sensor accessory, ensure sensor coverage aligns with occupancy patterns to avoid false triggers or dark zones.

How This Fixture Is Commonly Used

This fixture is typically installed in grid or linear patterns to provide uniform coverage across open floor areas. Spacing between fixtures is determined by mounting height, required light levels, and the 120° beam angle. In warehouse and manufacturing settings, fixtures are often spaced 15 to 20 feet apart at 25 to 30 foot mounting heights.

Higher output allows for reduced fixture count, but may increase glare if installed below 18 feet. For sports and gymnasium applications, fixtures are positioned to minimize shadows and support even illumination across playing surfaces. Layouts should account for racking, equipment, or obstructions that may affect light distribution.

Safety, Certifications, and Warranty

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

All components are suitable for use in commercial and industrial environments with elevated ambient temperatures and exposure to dust or moisture. The fixture meets requirements for use in high-ceiling spaces where robust construction and electrical safety are priorities.
