80 / 100 / 150 Watt Adjustable LED UFO High Bay | 12000 to 22500 Lumens | 4000K / 5000K Adjustable | 100-277V | Black or White Housing

Product Overview

This adjustable UFO high bay delivers 8,400 to 14,000 lumens at 5000K color temperature with a CRI of 80+. The wattage is field-selectable between 60, 80, and 100 watts, allowing output to be matched to actual site conditions without fixture replacement. Efficacy holds at 140 lumens per watt across all settings.

The fixture accepts 100-277V input at 50 or 60 Hz, with a power factor of 0.90 and THD capped at 20%. It supports 1-10V dimming and includes a 5-foot power cord and 8-inch dimming lead. The standard beam angle is 120 degrees through a polycarbonate lens.

Construction is aluminum alloy with a black finish. The fixture measures 9.2 x 7.1 inches and weighs 3.5 pounds. It mounts via an integrated eye-hook and is built for a rated lifespan of 170,000 hours at L70.

Where This Product Fits Best

This fixture replaces 150 to 250 watt metal halide systems. It suits spaces where load requirements vary between areas or where future adjustments may be needed as layouts change. The wattage selector accommodates different ceiling heights and task lighting demands within the same facility.

The IP65 rating allows use in areas exposed to dust accumulation and water spray from any direction. The IK08 impact rating supports installation in environments where incidental contact with objects is possible. Operating temperature range spans -22°F to 122°F, covering cold storage entries, loading docks, and process areas with elevated ambient heat.

Built-in 4kV surge protection addresses transient voltage events common in industrial electrical systems. This fixture is appropriate for manufacturing floors, warehouses, workshops, and maintenance bays where environmental exposure and electrical noise are present.

Performance and Functional Considerations

The 120-degree beam angle provides broad coverage suitable for general area lighting in open floor plans. Output scales linearly with wattage selection: 60 watts produces 8,400 lumens, 80 watts produces 11,200 lumens, and 100 watts produces 14,000 lumens.

The 1-10V dimming interface integrates with standard building automation and dimming controls. The 8-inch dimming cord keeps wiring compact at the fixture head. At full output, the fixture draws less than one amp at 277V.

The polycarbonate lens is impact-resistant and maintains optical clarity under UV exposure. The 5000K color temperature supports visual acuity in task-heavy environments and maintains consistent color rendering across mixed fixture installations.

Installation and Long-Term Use

The eye-hook mount accepts pendant drops, chains, or direct attachment to structure. The 5-foot cord provides working length for junction box placement above ceiling obstructions. At 3.5 pounds, the fixture can be supported by standard mounting hardware without additional reinforcement.

Wattage selection is made at the fixture using an onboard switch. This allows output to be adjusted during commissioning or later if space use changes. Once set, the fixture operates at the selected output without further intervention.

The aluminum alloy housing dissipates heat passively with no active cooling components. The IP65 seal protects internal electronics from washdown and airborne particulates. Expected service life of 170,000 hours at L70 reduces relamping frequency compared to legacy HID systems.

How This Fixture Is Commonly Used

Facilities typically set the wattage during initial installation based on measured light levels or layout requirements. In spaces with varying ceiling heights or aisle widths, different wattage settings can be applied to individual fixtures to balance coverage without adding fixture types.

The 1-10V dimming input is connected to building controls where occupied and unoccupied modes are managed centrally. In simpler installations, the dimming leads can be capped if dimming is not required.

A motion sensor is available as an accessory. If installed, default behavior and timing can be adjusted using a separate remote control. One remote is typically used per project to configure all sensors consistently.

Safety, Certifications, and Warranty

This fixture is ETL listed and DLC Premium qualified. We back this product with a 5-year warranty covering defects in materials and workmanship under normal use conditions.

The IP65 rating confirms the fixture resists dust ingress and water jets from any angle. The IK08 rating confirms resistance to moderate mechanical impact. Surge protection is rated at 4kV.
