150 / 200 / 240 Watt Adjustable LED UFO High Bay | 22500 to 36000 Lumens | 4000K / 5000K Adjustable | 100-277V | Black or White Housing

Product Overview

This is an adjustable wattage LED UFO high bay fixture designed for high-ceiling commercial and industrial interiors. The fixture supports selectable outputs of 150, 200, or 240 watts, delivering up to 36,000 lumens. Color temperature is field adjustable between 4000K and 5000K. Typical mounting heights range from 18 to 40 feet, making it suitable for large open spaces that require uniform, high-output illumination. The fixture is available in black or white housing and supports hook, pendant, or surface mounting.

Commonly deployed as a direct replacement for 400W to 1000W metal halide high bays, this model is used in environments where durability, flexibility, and consistent light levels are required. The fixture is UL and DLC Premium listed, IP65 and IK10 rated for demanding conditions, and includes integrated 0-10V dimming and motion sensor options.

Core Performance and Output

This UFO high bay provides selectable output levels of 22,500, 30,000, or 36,000 lumens, with an efficacy of 150 lumens per watt. The 120° beam angle delivers broad, even coverage suitable for open layouts and racked spaces. The fixture operates on 100-277V input and supports 50/60 Hz frequency. Color rendering index is 80+ for accurate visual tasks.

At maximum output, the fixture is best suited for mounting heights above 25 feet. Excessive output may cause glare or over-lighting in low bay or low ceiling applications. Uniformity may decrease at mounting heights above 40 feet without supplemental fixtures or narrower optics.

Adjustability and Control Options

Wattage and color temperature are field adjustable using onboard switches, allowing adaptation to changing requirements or energy targets. The fixture supports 0-10V dimming for integration with lighting controls and energy management systems. An optional motion sensor is available for occupancy-based control and further energy savings.

Adjustability supports phased upgrades or changes in space use without fixture replacement. All adjustments are accessible without opening the housing or disconnecting power.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) at ambient temperatures from -40°F to 122°F. The die-cast aluminum housing and polycarbonate lens provide impact resistance (IK10) and protection against dust and water ingress (IP65). Integrated 6kV surge protection guards against electrical disturbances common in industrial environments.

All components are designed for continuous operation in demanding commercial and industrial settings. No routine maintenance is required beyond periodic cleaning of the lens and housing.

Build Quality and Physical Characteristics

The fixture measures 12 inches in diameter by 7.8 inches high and weighs 7.5 pounds. The housing is die-cast aluminum with a durable finish in black or white. The polycarbonate lens is impact resistant and UV stable. All wiring is pre-installed with a 5-foot power cord and 8-inch dimming cord for straightforward connection.

Mounting options include hook, pendant, or surface brackets. The fixture is designed for single-point suspension or direct surface attachment to structural members. All hardware is corrosion resistant for long-term use in unconditioned spaces.

Where This Product Fits Best

This adjustable UFO high bay is intended for large, high-ceiling interiors requiring robust, high-output lighting. It is commonly used in:

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

The fixture is suitable for dusty, damp, or high-activity environments. IP65 and IK10 ratings support use in locations with airborne particulates, occasional water exposure, or risk of impact. Not intended for hazardous locations or environments requiring NSF or food-grade certification.

Installation and Long-Term Use

Installation supports hook, pendant, or surface mounting to steel structure, unistrut, or concrete. The fixture?s compact form factor and moderate weight allow single-person handling for most installations. All wiring is accessible for quick connection to existing circuits. 0-10V dimming and motion sensor wiring are pre-terminated for integration with controls.

Routine maintenance is limited to lens cleaning and periodic inspection of mounting hardware. No lamp or ballast replacements are required. The fixture is designed for continuous operation and frequent switching cycles without performance degradation.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 40 feet, with fixture spacing determined by output level and required light uniformity. In open warehouse or manufacturing layouts, fixtures are spaced 15 to 25 feet apart for general illumination. In sports or gymnasium applications, layout may be adjusted to minimize glare and optimize vertical illumination.

Higher output settings reduce fixture count but may increase glare or require careful aiming. Spacing and layout should be confirmed with a photometric plan for critical applications.

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. Integrated 6kV surge protection is standard. The fixture is covered by a 5-year warranty from date of installation.

All safety and certification markings are visible on the product label and in the installation manual. No special maintenance procedures are required to maintain certification status.
