100 / 120 / 150 / 200 / 240 Watt Adjustable LED UFO High Bay | 20000 to 45600 Lumens | 5000K | 100-277V | High Performance

Product Overview

This is an adjustable wattage LED UFO high bay designed for high ceiling commercial and industrial spaces. The fixture supports selectable outputs from 100 to 240 watts, delivering up to 45,600 lumens at 5000K. It is suitable for mounting heights from 18 to 40 feet, commonly replacing 400W to 1000W metal halide high bays in large open areas.

The fixture is built for demanding environments, with a die-cast aluminum housing, IP65 wet location rating, and IK08 impact resistance. Typical installations include warehouses, manufacturing facilities, and distribution centers where high output and durability are required.

Core Performance and Output

This UFO high bay provides five selectable wattage settings: 100W, 120W, 150W, 200W, and 240W. Output ranges from 20,000 to 45,600 lumens, with a maximum efficacy of 200 lumens per watt. The fixture supports both 4000K and 5000K color temperatures and maintains a CRI above 80 for accurate color rendering.

Standard beam angle is 120°, with optional 60° and 90° optics for controlled distribution. 1-10V dimming is included. At lower mounting heights, the highest output settings may create excessive brightness or glare. For mounting above 35 feet, narrower optics improve uniformity and reduce light loss.

Adjustability and Control Options

Wattage can be field-adjusted using an onboard selector, allowing tuning of light levels to match the application or energy requirements. The fixture is compatible with 1-10V dimming controls for integration with lighting management systems.

An optional motion sensor is available. Default sensor settings are 100% detection area, 3-minute hold time, 5-minute standby period, and 50% standby dimming. Sensor adjustments require a remote control (one per project recommended).

Longevity and Reliability

L70 rated life is 134,000 hours, supporting long-term operation in continuous-use environments. The fixture includes 4kV surge protection and is designed for ambient temperatures from -22°F to 122°F.

All components are housed in a sealed enclosure to prevent dust and water ingress. The polycarbonate lens and die-cast aluminum body provide impact resistance and thermal stability for demanding industrial use.

Build Quality and Physical Characteristics

The fixture measures 14.7 inches in diameter and 7.32 inches in height, with a total weight of 12 lbs. The housing is finished in black and constructed from die-cast aluminum for durability and heat dissipation.

IP65 and IK08 ratings ensure suitability for wet locations and areas with moderate mechanical impact risk. The fixture includes a 5-foot power cord and an 8-inch dimming cord for flexible installation. Mounting options include eye-hook (standard), pendant, or surface mount.

Where This Product Fits Best

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

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

Environments with high ceilings, open floor plans, and exposure to dust or moisture are suitable. The fixture?s IP65 rating supports use in locations where occasional washdown or airborne particulates are present.

Installation and Long-Term Use

Standard installation uses the included eye-hook for suspension from ceiling structure or unistrut. Pendant and surface mounting kits are available for alternate mounting requirements. The fixture?s 12 lb weight and compact form factor simplify handling during installation.

Long-term maintenance is minimal due to the sealed housing and long LED life. Motion sensor settings can be adjusted with a remote if occupancy control is required. Ensure mounting hardware is rated for the fixture?s weight and local seismic or vibration conditions.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 40 feet, with fixture spacing determined by output setting and required light levels. For 240W operation, wider spacing is possible, but glare control may be needed in visually sensitive areas.

Fixtures are often laid out in grid patterns for open areas or aligned with racking in warehouses. Higher output settings reduce fixture count but may require narrower optics to maintain uniformity and minimize spill light.

Safety, Certifications, and Warranty

This fixture is ETL listed and DLC Premium qualified. It carries an IP65 wet location rating and IK08 impact rating. Surge protection is rated at 4kV. The product is covered by a 5-year warranty from the date of installation.

All electrical and mounting work should comply with local codes and standards. The fixture is suitable for use in environments with ambient temperatures from -22°F to 122°F.

Frequently Asked Questions
