Product Overview
This is a 300 Watt UFO High Bay LED fixture designed for industrial and commercial spaces requiring high-output lighting. It delivers 45,000 lumens at 5000K, providing a daylight-white light suitable for large, open areas.
The fixture is built with a die-cast aluminum housing and a tempered glass lens. It is available in multiple voltage options: 100-277V, 277-480V, or 127-300VDC. The standard beam angle is 120 degrees, and the fixture supports 1-10V dimming.
It is rated for 164,000 hours (L70) of operation and is finished in black. The fixture comes with an eye-hook mount as standard, with pendant and surface mounting options available.
The fixture measures 16 inches in diameter by 8 inches in height and weighs 21 pounds. It includes a 5-foot power cord and an 8-inch dimming cord.
Where This Product Fits Best
This UFO High Bay is suited for warehouses, manufacturing plants, distribution centers, and other industrial environments with high ceilings and large open floor plans.
It is designed to replace 1000 Watt metal halide fixtures, providing a significant increase in efficiency and lifespan. The fixture is appropriate for spaces where consistent, high-output lighting is required.
With an IP65 rating, it can be used in areas exposed to dust and water jets, such as loading docks or production floors. The IK08 impact rating allows installation in locations where fixtures may be subject to moderate physical contact.
Multiple voltage options support compatibility with a range of electrical systems, including facilities operating on high-voltage or DC power.
Performance and Functional Considerations
The fixture delivers 150 lumens per watt, providing high efficiency for large-scale lighting applications. The 5000K color temperature produces a neutral white light suitable for task visibility and safety.
The 1-10V dimming capability allows integration with lighting controls for energy management or adaptive lighting strategies. The fixture operates on 50/60 Hz frequency and maintains a power factor of 0.90 with a maximum THD of 20%.
The tempered glass lens and die-cast aluminum housing contribute to durability in demanding environments. The fixture is rated for operation in temperatures from -22°F to 140°F.
The 120-degree beam angle provides wide, even coverage, reducing the number of fixtures needed in open areas.
Installation and Long-Term Use
The standard eye-hook mount supports quick installation to ceiling structures or trusses. Pendant and surface mounting options are available for alternate installation requirements.
The fixture's 5-foot power cord and 8-inch dimming cord provide flexibility for electrical connections. At 21 pounds, the fixture requires secure mounting points and may need two-person handling during installation.
The IP65 rating allows for installation in areas exposed to dust and water jets, supporting use in industrial washdown zones or partially covered outdoor spaces.
The fixture's 164,000-hour L70 lifespan reduces the frequency of maintenance and relamping compared to legacy metal halide systems.
