Product Overview

This 300 Watt UFO High Bay delivers 45,000 lumens at 5000K, designed for high-mount applications where strong, uniform illumination is required. The fixture is built with a die-cast aluminum housing and a tempered glass lens for durability in demanding environments.

It is available in three voltage configurations: 100-277V, 277-480V, or 127-300VDC. The standard beam angle is 120°, providing broad coverage. The fixture supports 1-10V dimming and operates at 50/60 Hz with a power factor of 0.90 and maximum THD of 20%.

The fixture measures 16 x 8 inches and weighs 21 lbs. It comes standard with an eye-hook mount, with pendant and surface mounting options available. The cord length is 5 feet, and the dimming cord is 8 inches.

This high bay is UL listed and DLC Premium qualified. It carries an IP65 rating for water and dust resistance and an IK08 rating for impact resistance. The rated lifespan is 164,000 hours (L70). A 5-year warranty is provided by LED Lighting Supply.

Where This Product Fits Best

This fixture is suited for large indoor spaces with high ceilings, such as warehouses, manufacturing plants, and distribution centers. It is designed to replace 1000 Watt metal halide fixtures, offering a direct LED alternative for high-output requirements.

The IP65 rating allows use in areas exposed to dust and water spray, including industrial environments where washdowns or airborne particulates are present. The IK08 rating supports installation in locations where fixtures may be subject to moderate physical impact.

Multiple voltage options support compatibility with a range of electrical systems, including standard commercial voltages and DC power sources. The fixture is appropriate for facilities operating on 100-277V, 277-480V, or 127-300VDC.

Mounting flexibility allows use in both new construction and retrofit projects, with eye-hook as standard and pendant or surface mounting as alternatives.

Performance and Functional Considerations

The fixture outputs 45,000 lumens at 150 lumens per watt, providing high efficiency for large-area lighting. The 5000K color temperature delivers a neutral white light suitable for task visibility and general illumination.

The 1-10V dimming capability allows integration with compatible dimming controls for adjustable output. The CRI of 70+ supports basic color rendering needs in industrial and commercial settings.

The tempered glass lens protects the LEDs while maintaining optical clarity. The die-cast aluminum housing manages heat effectively, supporting the long rated lifespan of 164,000 hours (L70).

The fixture operates at either 50 or 60 Hz, accommodating global power standards where supported by the specified voltage range. Power factor is 0.90, and total harmonic distortion is limited to 20% maximum.

Installation and Long-Term Use

The fixture is supplied with an eye-hook mount for suspension from ceiling structures. Pendant and surface mounting options are available for alternate installation requirements. The 5-foot cord provides flexibility for connection to overhead power sources.

At 21 lbs and 16 x 8 inches, the fixture requires secure mounting points and may need two-person handling for installation at height. The 8-inch dimming cord supports connection to external dimming controls if required.

The IP65 rating allows installation in areas subject to dust and water spray, reducing maintenance concerns in harsh environments. The IK08 rating provides resistance to moderate impacts, supporting use in active industrial spaces.

Routine cleaning of the tempered glass lens and inspection of mounting hardware are recommended for long-term reliability. The die-cast aluminum housing resists corrosion and supports heat dissipation over the fixture?s service life.

How This Fixture Is Commonly Used

After installation, this fixture provides consistent, high-output lighting for large spaces. The 1-10V dimming feature allows you to adjust light levels as needed for different tasks or occupancy patterns, provided compatible controls are in place.

The broad 120° beam angle delivers wide, even coverage, minimizing shadowing and reducing the number of fixtures needed in open areas. The fixture?s neutral white light supports visibility for detailed work and general movement.

Once mounted, the fixture requires minimal interaction beyond periodic cleaning and inspection. The robust housing and lens construction help maintain performance in environments with dust, moisture, or occasional impacts.

The fixture?s long rated lifespan reduces the frequency of replacements, supporting uninterrupted operation in facilities where access for maintenance is limited or costly.
