240 Watt Round LED UFO High Bay | 38400 Lumens | 5000K | 100-277V or 277-480V

Product Overview

This adjustable UFO high bay operates on 277-480V input and delivers field-selectable output across three wattage settings: 100W, 150W, or 200W. Corresponding lumen output ranges from 16,500 to 33,000 lumens at 165 lumens per watt. Color temperature is also adjustable on-site, with options for 3000K, 4000K, or 5000K.

The fixture replaces 400W to 1000W metal halide systems. It measures 11 x 6.9 inches, weighs 5 pounds, and includes a 4-foot cord. The die-cast aluminum housing is finished in black, and the polycarbonate lens provides a 90-degree beam angle. Rated lifespan is 100,000 hours at L70.

This high bay supports 0-10V dimming and operates across 50/60 Hz frequency with a power factor of .95. A motion sensor is available as an accessory. CRI is 80+.

Where This Product Fits Best

The 277-480V input makes this fixture appropriate for facilities with higher-voltage electrical infrastructure, which is common in warehouses, manufacturing plants, and distribution centers. The adjustable wattage and color temperature allow the same fixture to serve different zones or ceiling heights within a facility without requiring multiple fixture models.

IP69K and IK08 ratings support use in demanding environments. IP69K allows the fixture to withstand high-pressure, high-temperature washdown conditions. IK08 means the housing can handle moderate mechanical impact without damage. These ratings are relevant for food processing areas, cold storage, and industrial wash-down zones.

The operating temperature range of -31°F to 131°F supports both refrigerated storage and elevated-temperature industrial spaces. Surge protection rated at 6kV provides tolerance for electrical disturbances common in facilities with heavy motor loads or inconsistent power quality.

Performance and Functional Considerations

At the 200W setting, the fixture produces 33,000 lumens, which is appropriate for replacing 1000W metal halide in high-ceiling applications. The 100W setting at 16,500 lumens suits lower mounting heights or spaces where less output is needed. This range allows adjustment based on actual conditions observed after installation.

The 90-degree beam angle is a general-purpose distribution suitable for aisle lighting, open manufacturing floors, and storage areas. The polycarbonate lens is impact-resistant and maintains optical performance over time.

0-10V dimming compatibility allows integration with building automation systems or standalone dimming controls. The .95 power factor minimizes reactive power draw, which can be relevant for facilities monitoring electrical efficiency or operating near capacity on existing circuits.

Installation and Long-Term Use

The fixture mounts using an eye-hook, which is standard for chain or cable suspension in high bay applications. The 4-foot cord provides flexibility for connection to junction boxes positioned above the fixture. At 5 pounds, the fixture is manageable for single-person installation on a lift.

Wattage and color temperature selections are made on-site, typically via a switch or selector on the fixture housing. This allows installers to configure output based on ceiling height, reflectance, and task requirements observed during commissioning.

The 100,000-hour L70 lifespan reduces the frequency of lamp replacements compared to metal halide systems. The die-cast aluminum housing dissipates heat effectively, supporting long-term performance in continuous-duty applications.

How This Fixture Is Commonly Used

Facilities use the wattage selector to match output to ceiling height or daylight conditions in different zones. A fixture installed over a receiving dock might run at 200W, while the same fixture model in a lower-ceiling office area could be set to 100W. This flexibility is useful when lighting conditions vary across a single facility.

Color temperature adjustment is typically set during installation based on the type of work performed in the space. 5000K is often selected for inspection areas or task-intensive zones, while 3000K may be preferred in break rooms or customer-facing areas where a warmer appearance is appropriate.

The 0-10V dimming input allows connection to occupancy-based controls or daylight harvesting systems. Where dimming is not needed, the fixture operates at full output without additional configuration.

Safety, Certifications, and Warranty

This fixture is UL listed and rebate eligible. It carries a 5-year warranty from LED Lighting Supply.

Surge protection is rated at 6kV. The IP69K rating allows exposure to high-pressure, high-temperature water jets. IK08 indicates resistance to moderate mechanical impact.
