100 / 120 / 150 / 200 Watt Adjustable LED UFO High Bay | 15000 to 30000 Lumens | 5000K | 100-277V | White Housing

Product Overview

This 240 watt LED UFO high bay delivers 36,000 lumens at 5000K, operating on 277-480V input. The fixture replaces 1000 watt metal halide systems and produces 150 lumens per watt. A 120-degree beam angle with polycarbonate lens optics provides broad coverage from a compact housing measuring 12.8 x 9.1 inches.

The die-cast aluminum housing is IP65 rated for protection against dust ingress and water jets, and IK10 rated to withstand heavy physical impact. Operating temperature range spans -40°F to 113°F. The fixture includes a 5-foot power cord and an 8-inch dimming cord for 0-10V control connections.

This fixture is UL listed and DLC Premium qualified. Total weight is 8 lbs.

Where This Product Fits Best

The 277-480V input voltage makes this fixture appropriate for commercial and industrial facilities with higher voltage electrical distribution. Warehouses, manufacturing plants, and distribution centers commonly operate on these voltage systems.

IP65 and IK10 ratings allow installation in environments with airborne particulates, occasional washdown exposure, and risk of physical contact from moving equipment or material handling operations. The -40°F to 113°F operating range supports use in cold storage transitions, loading docks, and unconditioned industrial spaces.

At 36,000 lumens, this output level addresses spaces previously served by 1000 watt metal halide fixtures. Facilities replacing aging HID systems on 277-480V circuits can maintain or improve light levels while reducing connected load.

Performance and Functional Considerations

The 5000K color temperature produces a cool white appearance suited to task-intensive work environments where visual clarity supports safety and productivity. CRI of 80+ provides adequate color rendering for general industrial and commercial applications.

The 0-10V dimming capability allows integration with building automation systems or manual dimmer controls. Power factor is rated at 0.90, with total harmonic distortion held to 20% maximum. The 4kV surge protection helps the fixture tolerate electrical transients common in industrial power environments.

Rated lifespan is 50,000 hours at L70, meaning lumen output is projected to remain at or above 70% of initial output through that operating period.

Installation and Long-Term Use

Mounting options include hook or pendant configurations. The 5-foot power cord provides flexibility for connection to junction boxes positioned above the mounting point. The 8-inch dimming cord allows access to 0-10V control wiring when dimming integration is required.

The fixture weighs 8 lbs, which is manageable for single-person installation in most ceiling access situations. Die-cast aluminum construction and the IK10 impact rating reduce concern about damage during installation or from incidental contact over time.

The 50,000-hour rated lifespan supports extended intervals between replacements in facilities where access to high bay mounting locations requires lifts or scheduled shutdowns.

How This Fixture Is Commonly Used

Facilities typically use the hook mount when suspending the fixture from chain or aircraft cable, and the pendant option when a rigid drop is preferred. The mounting method selected usually depends on ceiling structure and access requirements for future maintenance.

The 0-10V dimming cord allows connection to external controls when light level adjustment is needed. In spaces with variable occupancy or daylight contribution, operators use dimming to reduce output during periods when full brightness is not required.

A motion sensor is available for this fixture. When used, the sensor enables automatic response to occupancy, reducing energy use in areas with intermittent activity.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The IP65 rating allows use in locations exposed to dust and directed water spray. The IK10 rating allows use in locations where physical impact from equipment, materials, or personnel is possible.

Surge protection is rated at 4kV, addressing transient voltage events on industrial electrical systems. The operating temperature range of -40°F to 113°F supports installation in both cold and warm environments within those limits.

We provide a 5-year warranty on this fixture.
