100 / 120 / 150 / 200 Watt Adjustable UFO High Bay | 14000 to 28000 Lumens | 5000K | 100-277V | Black

Product Overview

This is an adjustable wattage LED UFO high bay fixture designed for high ceiling commercial and industrial spaces. The fixture supports selectable outputs of 100, 120, 150, or 200 watts, delivering up to 28,000 lumens at 5000K. Typical installations include warehouse, manufacturing, and distribution environments with mounting heights from 15 to 35 feet. The fixture is ETL and DLC Premium listed, IP65 rated for dust and water ingress, and features a robust aluminum alloy housing with IK08 impact protection.

Standard mounting is via eye-hook, with optional pendant mounting available. The fixture includes a motion sensor with configurable settings and supports 1-10V dimming. This model is commonly used as a direct replacement for 250W or 400W metal halide high bays in both retrofit and new construction projects.

Core Performance and Output

The fixture provides selectable output levels of 14,000, 16,800, 21,000, or 28,000 lumens, with a system efficacy of 140 lumens per watt. The 120° polycarbonate lens delivers wide, uniform coverage suitable for open floor layouts and racked spaces. Color temperature is fixed at 5000K with a CRI above 80 for accurate color rendering in task-critical environments.

Power factor is 0.90 with a maximum THD of 20%. The fixture operates on 100-277V input at 50/60Hz. At lower mounting heights, the 200W setting may produce excessive brightness and glare; at higher mounting heights above 35 feet, uniformity may decrease without supplemental fixtures or tighter spacing.

Adjustability and Control Options

Wattage is field-selectable via onboard controls, allowing adjustment between 100, 120, 150, and 200 watts to match required light levels or energy targets. The fixture supports 1-10V dimming for integration with lighting controls or building management systems.

An integrated motion sensor is included, with default settings of 100% detection area, 3-minute hold time, 5-minute standby period, and 50% standby dimming. A remote control (required for changes) allows adjustment of sensor parameters. This supports occupancy-based energy savings and flexible scheduling.

Longevity and Reliability

The fixture is rated for 170,000 hours (L70) at typical operating conditions. The aluminum alloy housing and polycarbonate lens provide resistance to impact and environmental stress. The fixture includes 4kV surge protection for electrical reliability in industrial settings.

Operating temperature range is -22°F to 122°F, supporting deployment in both conditioned and unconditioned spaces. The IP65 rating ensures protection against dust and water spray, suitable for most indoor industrial environments.

Build Quality and Physical Characteristics

The fixture measures 11.02 inches in diameter by 7.72 inches in height and weighs 5.5 lbs. The housing is black powder-coated aluminum alloy for corrosion resistance and durability. The lens is impact-resistant polycarbonate, rated IK08 for mechanical protection.

Standard cord length is 5 feet, with an 8-inch dimming cord for control wiring. Mounting is via eye-hook as standard, with pendant mounting available as an option. The fixture is designed for quick installation and long-term serviceability.

Where This Product Fits Best

This adjustable UFO high bay is suited for large, open indoor spaces with mounting heights from 15 to 35 feet. It is commonly deployed in environments requiring robust construction, high output, and flexible control options.

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

The fixture is suitable for locations exposed to dust, humidity, and moderate impact. Not intended for environments with corrosive chemicals or continuous wet conditions.

Installation and Long-Term Use

Standard installation uses the included eye-hook for suspension from ceiling structure or unistrut. Pendant mounting is available for rigid conduit installations. The fixture?s compact size and light weight allow for single-person handling in most cases.

All wiring is accessible via the top of the fixture. The IP65 enclosure does not require additional gasketing for typical indoor use. Routine maintenance is limited to periodic cleaning of the lens and inspection of mounting hardware. Sensor settings can be adjusted with the remote as needed for occupancy or scheduling changes.

How This Fixture Is Commonly Used

Typical mounting heights range from 15 to 35 feet, depending on output setting and target light levels. Spacing is generally 12 to 20 feet on center for open layouts, with closer spacing in racked or task-intensive areas. The fixture is often deployed in grid patterns for uniform coverage.

Higher output settings reduce fixture count but may increase glare in low-ceiling applications. Sensor-based control is used to reduce energy use during periods of low occupancy. Adjustability allows tuning after installation to meet changing operational needs.

Safety, Certifications, and Warranty

This fixture is ETL listed and DLC Premium qualified. It is rated IP65 for dust and water ingress and IK08 for impact resistance. Surge protection is 4kV. The product includes a 5-year warranty covering manufacturing defects and performance.

All safety and certification markings are present on the product label. The fixture is suitable for use in commercial and industrial environments meeting these standards.
