80 / 100 / 150 Watt Adjustable LED UFO High Bay | 12000 to 22500 Lumens | 4000K / 5000K Adjustable | 100-277V | Black or White Housing

Product Overview

This LED UFO high bay provides field-adjustable wattage at 80, 100, or 150 watts, delivering 12,000, 15,000, or 22,500 lumens respectively. Efficacy is 150 lumens per watt across all output settings. Color temperature is also adjustable between 4000K and 5000K.

The fixture operates on 100-277V input at 50/60 Hz with a power factor of 0.90. It replaces 250 or 400 watt metal halide fixtures. CRI is 80+, and the standard beam angle is 90 degrees through a polycarbonate lens.

Housing is die-cast aluminum, available in black or white. The fixture measures 7.7 x 10.8 inches, weighs 4.5 lbs, and includes a 5-foot power cord with an 8-inch dimming cord. Rated lifespan is 50,000 hours at L70.

Where This Product Fits Best

This fixture is sized and rated for warehouse aisles, manufacturing bays, storage areas, and similar spaces where 250 to 400 watt metal halide fixtures are currently installed. The IP65 rating allows installation in areas with dust exposure and water spray from any direction, such as wash-down zones, loading docks, or partially enclosed industrial spaces.

The operating temperature range of -40°F to 113°F supports use in cold storage environments, unheated buildings, and facilities with elevated ambient temperatures from equipment or process heat. The 6kV surge protection handles electrical transients common in industrial electrical systems.

Hook or surface mounting options accommodate chain-hung applications over open floor areas or direct attachment to structure in spaces with limited clearance.

Performance and Functional Considerations

The three-step wattage adjustment allows output to be set based on ceiling height, spacing, and task requirements at the time of installation. Selecting 80 watts provides 12,000 lumens, 100 watts provides 15,000 lumens, and 150 watts provides 22,500 lumens. All three settings maintain 150 lumens per watt.

The selectable 4000K and 5000K color temperatures allow matching to existing fixtures in the space or to preference for warmer or cooler light appearance. The 90-degree beam angle provides broad coverage appropriate for general area lighting at typical high bay mounting heights.

The 0-10V dimming input allows integration with building automation systems or wall-mounted dimmers for occupancy-based or daylight harvesting control strategies. A motion sensor is available for this fixture.

Installation and Long-Term Use

The 5-foot power cord provides flexibility for electrical connections above drop ceilings or in open structure installations. The 8-inch dimming cord keeps 0-10V wiring separate from line voltage. At 4.5 lbs, the fixture is manageable for single-person installation in most conditions.

Wattage and color temperature selections are made at the fixture before or during installation. Hook mounting allows chain suspension with standard hardware. Surface mounting provides direct attachment to junction boxes or structural members.

Die-cast aluminum housing dissipates heat effectively over the 50,000-hour rated lifespan. The polycarbonate lens resists impact in active work environments. IP65 construction eliminates the need for supplemental enclosures in dusty or wet locations within the rated exposure limits.

How This Fixture Is Commonly Used

Maintenance and facility teams use the wattage adjustment to match output to actual conditions once the fixture is in place. A space with lighter-colored walls and floors may need only 80 watts where 150 watts would be appropriate over darker surfaces or in taller bays. This adjustment is made once and does not require re-entry to the fixture during normal operation.

The color temperature switch gives installers control over light appearance without needing to specify fixtures separately for different areas. A 4000K setting is often preferred in spaces where personnel spend extended time, while 5000K is common in task-focused or inspection areas.

The 0-10V dimming input connects to standard building controls. When dimming is not required, the dimming leads can be capped. The fixture operates at full output of the selected wattage setting when no dimming signal is present.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The IP65 rating allows exposure to dust and water jets without ingress to internal components. Surge protection is rated at 6kV.

We back this fixture with a 5-year warranty.
