120 / 160 / 200 Watt Adjustable UFO High Bay | 19800 to 33000 Lumens | 4000K / 5000K | 100-277V | White or Black Housing | Frosted Lens

Product Overview

This adjustable UFO high bay is designed for high-ceiling commercial and industrial interiors requiring robust, efficient illumination. The fixture supports selectable wattages of 120, 160, or 200 watts, delivering up to 33,000 lumens. Typical installations include warehouses, manufacturing facilities, and distribution centers with mounting heights from 15 to 35 feet. The fixture is available in black or white housing with a frosted lens for diffused output.

It is engineered as a direct replacement for 250W or 400W metal halide high bays. The fixture supports hook, pendant, or surface mounting, and is suitable for both new construction and retrofit projects where flexibility and long-term reliability are required.

Core Performance and Output

This UFO high bay provides selectable output levels: 19,800 lumens at 120W, 26,400 lumens at 160W, and 33,000 lumens at 200W. Efficacy is 165 lumens per watt. The 120° beam angle and frosted polycarbonate lens deliver wide, uniform coverage with reduced glare. Color temperature is field-selectable between 4000K and 5000K.

1-10V dimming is standard. The fixture operates on 100-277V input and is compatible with occupancy sensors. Output is best suited for mounting heights between 18 and 35 feet; at lower heights, output may be excessive and increase glare. Uniformity may decrease at mounting heights above 35 feet without supplemental fixtures.

Adjustability and Control Options

Wattage and color temperature are field adjustable, allowing adaptation to changing requirements or energy targets. The fixture supports three wattage settings and two color temperatures. A motion sensor is available for occupancy-based control, with default settings of 100% detection area, 3-minute hold time, 5-minute standby, and 50% standby dimming.

Sensor settings are adjustable via remote (one remote required per project). 1-10V dimming enables integration with lighting control systems. The fixture can be configured for hook, pendant, or surface mounting to match site conditions.

Longevity and Reliability

L70 rated life is 134,000 hours. The fixture is designed for continuous operation in demanding environments, with an operating temperature range from -22°F to 122°F. Surge protection is rated at 6kV.

IP65 and IK08 ratings provide protection against dust, water jets, and moderate impact. The fixture is covered by a 5-year warranty. Aluminum alloy housing and polycarbonate lens resist corrosion and physical damage in typical industrial settings.

Build Quality and Physical Characteristics

The fixture housing is cast aluminum alloy with a powder-coated finish in black or white. The frosted polycarbonate lens diffuses light and minimizes glare. The fixture measures 11.8 inches in diameter and 6.6 inches in height, with a weight of 5.1 lbs.

Standard cord length is 4 feet, with an 8-inch dimming cord. The fixture supports hook mounting by default, with pendant and surface mounting options available. All components are designed for tool-accessible installation and maintenance.

Where This Product Fits Best

This UFO high bay is suitable for large, open indoor spaces with high ceilings and demanding lighting requirements. It is commonly installed in environments where durability, output flexibility, and long service life are required.

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

IP65 rating supports use in dusty or damp locations. The fixture is not intended for corrosive, hazardous, or outdoor environments. Output and beam angle are optimized for open-plan layouts and high ceilings.

Installation and Long-Term Use

The fixture is designed for single-point hook mounting as standard, with pendant and surface mounting options for alternate ceiling types. Installation requires a single electrical connection and supports 100-277V input. The fixture is lightweight for its output class, simplifying overhead installation.

Maintenance is limited to periodic cleaning of the lens and housing. Field adjustability allows for changes in output or color temperature without fixture replacement. Motion sensor settings can be modified with a remote as needed. All components are accessible for inspection and service.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 35 feet, with fixture spacing determined by output level and required light levels. For general warehouse or manufacturing use, fixtures are often spaced 15 to 25 feet apart in a grid or row pattern. In gymnasiums or sports facilities, layout may be adjusted to minimize glare and maximize uniformity.

Higher output settings reduce fixture count but may increase perceived glare at lower mounting heights. Spacing and layout should be coordinated with racking, equipment, or court lines to avoid shadowing and ensure consistent coverage.

Safety, Certifications, and Warranty

This fixture is ETL listed and DLC Premium certified. It is rated IP65 for water and dust ingress and IK08 for impact resistance. Surge protection is 6kV. The fixture is covered by a 5-year warranty from date of installation.

All electrical and mounting work should follow local code requirements. The fixture is suitable for use in dry or damp indoor locations. Not for use in classified hazardous or corrosive environments.
