240 Watt LED UFO High Bay | 36000 Lumens | 5000K | 277-480V

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 from the polycarbonate lens provides broad coverage without supplemental optics.

The die-cast aluminum housing measures 12.8 x 9.1 inches and weighs 8 pounds. A 5-foot power cord and 8-inch dimming cord are included. The fixture supports 0-10V dimming and is compatible with available motion sensor accessories.

Where This Product Fits Best

The 277-480V input makes this fixture appropriate for commercial and industrial electrical systems commonly found in warehouses, manufacturing floors, and distribution facilities. The higher voltage range eliminates compatibility with standard 120V or 208V circuits.

IP65 and IK10 ratings allow installation in spaces with airborne dust, occasional washdown exposure, and physical impact risk from equipment or material handling. The operating temperature range of -40°F to 113°F supports use in cold storage entries, unheated warehouse bays, and climate-controlled production areas.

Performance and Functional Considerations

At 36,000 lumens, this fixture provides output appropriate for high-ceiling applications where 1000 watt metal halide lamps were previously specified. The 5000K color temperature produces a cool white output commonly used in industrial and logistics environments where visual clarity and color distinction matter.

CRI of 80+ supports accurate color rendering for inspection tasks, product identification, and general work visibility. The 120-degree beam angle distributes light across a wide area, which typically reduces the number of fixtures needed compared to narrower optics.

The 50,000-hour L70 lifespan indicates the point at which output is expected to decline to 70% of initial lumens. Power factor of .90 and THD at 20% max reflect electrical performance within standard commercial power quality expectations.

Installation and Long-Term Use

Mounting options include hook or pendant configurations. The 5-foot cord length provides flexibility during rough-in, and the 8-inch dimming cord allows connection to 0-10V control circuits without field splicing in most installations.

The 4kV surge protection rating reduces the risk of driver failure from transient voltage spikes common in industrial electrical environments. Die-cast aluminum construction and IK10 impact resistance support long-term durability in high-activity facilities where fixtures may be struck by forklifts, racking systems, or moving equipment.

IP65 ingress protection allows the fixture to tolerate dust-laden air and water spray from cleaning operations or condensation in humid environments. The black finish minimizes visible soiling in industrial settings.

How This Fixture Is Commonly Used

Facilities replacing aging metal halide high bays often use this fixture as a direct swap where 277V or 480V circuits are already in place. The hook mount allows reuse of existing suspension points in many cases, while pendant mounting suits structured ceiling systems or chain drops.

The 0-10V dimming input connects to building automation systems or standalone dimmers to reduce output during low-activity periods or to meet occupancy-based control requirements. A motion sensor accessory is available for installations requiring occupancy-based switching or dimming without a separate control system.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The 5-year warranty covers defects in materials and workmanship under normal use conditions.

Frequently Asked Questions

What voltage does this fixture require?
This fixture operates on 277-480V input only. It is not compatible with 120V or 208V circuits.

What does this fixture replace?
It is sized to replace 1000 watt metal halide high bays in similar mounting positions and ceiling heights.

Is this fixture eligible for utility rebates?
DLC Premium qualification makes this fixture eligible for rebate programs that recognize DLC-listed products. Rebate availability and amounts vary by utility.

Can this fixture be dimmed?
