150 Watt LED UFO High Bay | 21700 Lumens | 5000K | 277-480V

Product Overview

This 150 watt LED UFO high bay delivers 21,700 lumens at 5000K with a color rendering index of 80 or higher. The fixture operates on 277-480V input and replaces 400 watt or 1000 watt metal halide fixtures. Efficacy is 145 lumens per watt.

The housing is die-cast aluminum with a black finish. A polycarbonate lens provides optical coverage at a 120-degree beam angle. The fixture measures 11.6 by 8.5 inches and weighs 10 pounds. A 5-foot power cord and 8-inch dimming cord are included.

This fixture supports 0-10V dimming and includes a motion sensor. Mounting options are hook or surface. Rated lifespan is 50,000 hours at L70.

Where This Product Fits Best

The 277-480V input voltage makes this fixture appropriate for commercial and industrial electrical systems commonly found in warehouses, manufacturing plants, and distribution facilities. It is not compatible with 120V or standard 208V circuits.

IP65 rating allows installation in spaces exposed to dust accumulation and water spray from any direction. This includes washdown areas, food processing zones, and facilities with high airborne particulate levels. IK10 impact rating supports use in environments where the fixture may be struck by equipment, forklifts, or debris.

The operating temperature range of -40 degrees Fahrenheit to 113 degrees Fahrenheit accommodates cold storage applications as well as unconditioned warehouse spaces that experience seasonal heat buildup.

Performance and Functional Considerations

At 21,700 lumens, this fixture is sized for direct replacement of 400 watt or 1000 watt metal halide high bays. The 5000K color temperature produces a neutral white output commonly specified for industrial task lighting and general warehouse illumination.

The 120-degree beam angle provides broad coverage from each fixture position. Power factor is 0.90 with total harmonic distortion at 20 percent maximum. The fixture operates on both 50Hz and 60Hz systems.

Built-in 4kV surge protection helps the fixture withstand electrical transients without damage to the driver or LEDs.

Installation and Long-Term Use

The fixture mounts using either a hook or surface mount configuration. At 10 pounds, the unit can be handled by a single installer in most ceiling access situations. The 5-foot power cord provides working length for junction box connections without requiring field splices in typical drop installations.

The 8-inch dimming cord connects to 0-10V control systems where building-level dimming is present. Die-cast aluminum construction and IP65 sealing reduce the need for cleaning or relamping over the rated 50,000-hour lifespan.

How This Fixture Is Commonly Used

Facilities replacing metal halide high bays use this fixture to maintain or improve light levels while reducing connected load. The 277-480V compatibility allows direct connection to existing high bay circuits without transformer changes in most industrial buildings.

The 0-10V dimming input allows integration with building automation systems or manual dimming controls where light level adjustment is needed. A motion sensor is available for occupancy-based control in aisles, storage zones, or areas with intermittent activity.

The IP65 and IK10 ratings make the fixture suitable for environments where overhead equipment may contact fixtures or where cleaning with pressurized water occurs. Cold storage facilities benefit from the minus 40 degree Fahrenheit low-end operating range.
