Where This Product Fits Best

This adjustable LED UFO high bay is suited for large indoor spaces with high ceilings, such as warehouses, manufacturing plants, and gymnasiums. It is intended to replace 400 or 1000 watt metal halide fixtures.

The fixture is compatible with 100-277V electrical systems, making it suitable for a wide range of commercial and industrial facilities. The selectable wattage and color temperature allow adaptation to different lighting requirements within the same space.

With an IP65 rating, the fixture can be used in areas exposed to dust and low-pressure water jets. The IK10 rating supports use in locations where impact resistance is needed.

Performance and Functional Considerations

The fixture delivers up to 145 lumens per watt, providing high efficiency for large-area illumination. The 0-10V dimming capability allows integration with lighting controls for further energy management.

The color temperature can be set to either 4000K or 5000K, supporting both neutral and cooler white light preferences. Wattage adjustability enables output tuning based on the specific needs of the space.

The polycarbonate lens and 110-degree beam angle provide broad, even light distribution. The fixture operates reliably in temperatures from -40°F to 113°F.

Power factor is rated at 0.90, and total harmonic distortion is 20% max. Surge protection is built in at 4kV.

Installation and Long-Term Use

Mounting options include hook and pendant as standard, with surface mounting available. The fixture's weight and dimensions are manageable for single-person installation in most cases.

The 5-foot power cord and 8-inch dimming cord provide flexibility for connection to existing wiring and controls. The die-cast aluminum housing and polycarbonate lens are designed for durability in industrial environments.

With a rated lifespan of 50,000 hours at L70, the fixture is intended for long-term operation with minimal maintenance. The IP65 and IK10 ratings support use in challenging conditions, including areas with dust, moisture, or risk of impact.

Routine cleaning and inspection are recommended to maintain performance, especially in dusty or high-traffic areas.

How This Fixture Is Commonly Used

After installation, the selectable wattage and color temperature allow you to adjust the fixture to match the lighting needs of the space. This is useful when requirements change or when optimizing for different tasks or activities.
