300 / 400 / 500 Watt Adjustable UFO High Bay | 44900 to 79100 Lumens | 4000K / 5000K | 100-277V

Product Overview

This UFO high bay fixture provides selectable wattage options of 300, 400, or 500 watts, delivering lumen outputs from 44,900 up to 79,100. The fixture supports both 4000K and 5000K color temperatures, with a CRI of 80+ for general industrial and commercial applications.

The fixture operates on 100-277V input and supports 0-10V dimming. It is designed to replace 1500 or 2000 watt metal halide systems. The standard beam angle is 90°, and the fixture uses a polycarbonate lens for durability.

The housing is constructed from aluminum alloy and finished in black. The fixture measures 17.7 inches in diameter and 10.6 inches in height, with a total weight of 14.5 lbs.

Color temperature and wattage are both adjustable at the fixture. The mounting method is eye-hook.

Where This Product Fits Best

This fixture is suitable for large indoor spaces requiring high lumen output, such as warehouses, manufacturing plants, and distribution centers. It is designed for environments where legacy 1500 or 2000 watt metal halide fixtures are currently used.

The IP65 rating allows use in locations exposed to dust and water jets, such as industrial production areas or covered loading docks. The fixture operates reliably in ambient temperatures from -22°F to 122°F.

The selectable wattage and color temperature provide flexibility for spaces with changing requirements or where lighting needs may evolve over time.

The 90° beam angle is appropriate for high bay mounting heights where focused, uniform illumination is required.

Performance and Functional Considerations

The fixture delivers up to 155 lumens per watt, supporting energy-efficient operation in high ceiling environments. The 0-10V dimming capability allows integration with compatible dimming controls for further energy management.

With a rated lifespan of 170,000 hours (L70), the fixture is designed for long-term use with minimal maintenance. The power factor of 0.95 and THD of 20% support stable electrical performance.

The fixture includes 6kV surge protection for added reliability in areas with electrical disturbances. The IK08 rating provides resistance to moderate mechanical impact.

The polycarbonate lens and aluminum alloy housing contribute to overall durability in demanding industrial settings.

Installation and Long-Term Use

The fixture is designed for eye-hook mounting, which is standard for high bay installations. The total weight of 14.5 lbs allows for manageable handling during installation.

All adjustments for wattage and color temperature are made at the fixture, supporting field configuration without the need for fixture replacement. The fixture is compatible with 100-277V power supplies and operates at 50/60 Hz.

The IP65 rating allows for installation in areas where exposure to dust and water jets is expected. The fixture is suitable for use in ambient temperatures ranging from -22°F to 122°F.

Routine maintenance is minimized due to the long rated lifespan and robust construction. The fixture is covered by a 5-year warranty from LED Lighting Supply.

How This Fixture Is Commonly Used

After installation, you can adjust both the wattage and color temperature directly at the fixture to match the lighting requirements of your space. This allows for on-site tuning if lighting needs change due to layout modifications or operational shifts.

The 0-10V dimming interface can be connected to compatible dimming systems for further control over light levels. This is often used in facilities where lighting schedules or occupancy patterns vary.

The fixture’s 90° beam angle provides focused illumination, which is effective for high bay applications where uniform light distribution is needed over work areas or aisles.

Once installed, the fixture operates with minimal attention required. The robust housing and lens construction support reliable use in environments with dust, moisture, or occasional mechanical impact.
