250 / 375 / 500 Watt Adjustable UFO High Bay | 38700 to 76800 Lumens | 4000K / 5000K | 277-480V

Product Overview

This UFO high bay fixture provides selectable wattage options of 250, 375, or 500 watts, delivering lumen outputs from 38,700 up to 76,800. It is designed for use on 277V to 480V electrical systems and supports both 4000K and 5000K color temperatures.

The fixture uses an aluminum alloy housing with a polycarbonate lens and is finished in black. It offers a 90-degree beam angle and supports 0-10V dimming. The fixture is rated for 150,000 hours (L70) and weighs 28 lbs with dimensions of 19 inches in diameter by 17 inches in height.

Mounting options include eye-hook or yoke. The fixture operates at 50/60 Hz, has a power factor of 0.95, and a total harmonic distortion of 20%.

It is equipped with 10kV surge protection and is rated for operation in temperatures from -22°F to 122°F.

Where This Product Fits Best

This fixture is suitable for large commercial and industrial spaces requiring high-output lighting, such as warehouses, manufacturing plants, and distribution centers. It is intended to replace 1500 or 2000 watt metal halide systems.

The selectable wattage and color temperature allow for adaptation to different lighting requirements within the same facility. The 277-480V compatibility supports use in facilities with higher voltage electrical infrastructure.

Its IP65 rating allows installation in areas exposed to dust and water jets, while the IK08 rating supports use in environments where moderate impact resistance is needed.

The fixture?s size and weight should be considered when planning installation, especially for overhead mounting or retrofits in existing spaces.

Performance and Functional Considerations

The fixture delivers up to 155 lumens per watt, supporting high efficiency in large spaces. The 0-10V dimming capability allows for integration with compatible dimming controls.

Color temperature can be set to either 4000K or 5000K, providing flexibility for different visual tasks or preferences. The CRI of 80+ supports accurate color rendering in work environments.

The 90-degree beam angle is suitable for general area lighting in high bay applications. The polycarbonate lens provides durability and uniform light distribution.

10kV surge protection is included for electrical reliability in facilities with power quality concerns. The fixture is designed to operate reliably in a wide temperature range.

Installation and Long-Term Use

Mounting options include both eye-hook and yoke, allowing for adaptation to different ceiling structures or retrofit conditions. The fixture?s weight and dimensions require secure mounting and may influence installation planning.

The aluminum alloy housing and IP65 rating allow for use in environments with dust and water exposure. The IK08 rating provides resistance to moderate impacts during maintenance or operation.

The fixture is rated for 150,000 hours (L70), supporting long-term use with minimal maintenance. The 5-year warranty is provided by LED Lighting Supply.

Selectable wattage and color temperature can be set during installation to match site requirements. Dimming can be implemented where compatible controls are present.

How This Fixture Is Commonly Used

After installation, you can set the wattage and color temperature to match the lighting needs of your space. This allows adjustment for changes in layout or task requirements without replacing the fixture.

The 0-10V dimming feature lets you connect the fixture to a compatible dimming system for further control over light levels. This is often used to reduce output during periods of low activity or to meet specific lighting protocols.

The fixture?s beam angle and output are suited for open areas with high ceilings, providing broad, uniform illumination. The polycarbonate lens is durable and easy to clean during routine maintenance.

Once installed, the fixture operates reliably in a range of temperatures and is protected against dust, water jets, and moderate impacts. This reduces the need for frequent servicing in demanding environments.
