Where This Product Fits Best
This UFO high bay is suitable for large indoor spaces with high ceilings, such as warehouses, manufacturing plants, and distribution centers. It is intended for applications where high lumen output is required to replace 1500W or 2000W metal halide fixtures.
The adjustable wattage and color temperature allow for adaptation to different lighting requirements within the same facility. The fixture is compatible with standard 100V-277V electrical systems found in most commercial and industrial environments.
IP65 and IK08 ratings make this fixture appropriate for areas exposed to dust, moisture, and moderate physical contact. The operating temperature range of -22°F to 122°F supports use in both refrigerated and high-heat environments.
Performance and Functional Considerations
The selectable wattage feature allows adjustment of light output to match specific area requirements or energy management goals. Lumen output ranges from 44,900 to 79,100 lumens, with a consistent efficacy of 155 lumens per watt.
Color temperature can be set to either 4000K or 5000K, supporting both neutral and cool white lighting preferences. The fixture maintains a CRI of 80+ for accurate color rendering in work environments.
0-10V dimming is supported for integration with compatible lighting controls. The fixture operates at 50/60 Hz and maintains a power factor of 0.95 with total harmonic distortion at 20%.
Polycarbonate optics and a 90-degree beam angle provide focused, uniform illumination suitable for high bay applications.
Installation and Long-Term Use
The fixture is designed for eye-hook mounting, which is standard for high bay installations. The 17.7-inch diameter and 10.6-inch height allow for straightforward handling and placement.
Aluminum alloy construction and a black finish provide durability and corrosion resistance. The IP65 rating protects against water jets and dust ingress, supporting use in demanding environments.
IK08 impact protection allows the fixture to withstand moderate impacts from equipment or incidental contact. Surge protection up to 6kV is built in for electrical reliability.
The rated lifespan of 170,000 hours reduces the frequency of maintenance and replacement in continuous-use facilities. The fixture is covered by a 5-year warranty from LED Lighting Supply.
How This Fixture Is Commonly Used
After installation, you can set the wattage and color temperature to match the needs of each area. This is done before energizing the fixture, allowing for flexibility if lighting requirements change over time.
The 0-10V dimming interface allows you to connect the fixture to compatible dimming systems for further control of light levels. The fixture is typically left in place for extended periods due to its long rated life and robust construction.
Routine cleaning and inspection are straightforward due to the fixture's sealed design and impact-resistant housing. The eye-hook mount allows for easy removal or repositioning if needed during facility reconfiguration.
Once installed, the fixture provides consistent, high-output illumination for large spaces, supporting safe and efficient operations in industrial and commercial settings.
