80 / 90 / 105 Watt Adjustable Linear LED High Bay | 12000 to 15750 Lumens | 4000K / 5000K Adjustable | 100-277V | 2 Foot

Product Overview

This 150 watt LED UFO high bay delivers 21,700 lumens at 5000K color temperature, operating on 277-480V input. The fixture replaces 400 to 1000 watt metal halide systems and produces 145 lumens per watt with a CRI of 80+.

The die-cast aluminum housing measures 11.6 x 8.5 inches and weighs 10 pounds. A polycarbonate lens distributes light in a 120-degree beam angle. The fixture includes a 5-foot power cord and an 8-inch dimming cord for 0-10V dimming connections.

Rated lifespan is 50,000 hours at L70. The fixture is UL listed and DLC Premium qualified.

Where This Product Fits Best

This high bay operates on 277-480V systems, which limits installation to facilities with three-phase commercial or industrial electrical service. Buildings running 120V or standard 120-277V circuits will require a different voltage configuration.

The IP65 rating allows the fixture to handle washdowns, high-humidity areas, and environments with airborne dust or particulates. IK10 impact resistance makes it suitable for spaces where accidental contact from equipment, forklifts, or overhead crane activity is a concern.

Operating temperature range spans -40°F to 113°F, supporting installation in cold storage, freezers, and facilities without climate control. The 4kV surge protection addresses electrical environments with transient spikes from motors, compressors, or variable frequency drives.

Performance and Functional Considerations

At 21,700 lumens from 150 watts, this fixture is sized as a direct replacement for 400 to 1000 watt metal halide lamps. Facilities removing legacy HID systems will see a significant reduction in connected load while maintaining comparable light output.

The 5000K color temperature produces a cool white light commonly used in industrial and warehouse applications where visual clarity and contrast are priorities. CRI of 80+ supports accurate color rendering for inspection, sorting, and general task visibility.

Power factor is rated at 0.90 with THD held to 20% max, which keeps the fixture within typical utility and facility electrical quality thresholds. The 50/60 Hz frequency compatibility covers standard North American and international power systems.

Installation and Long-Term Use

The fixture mounts via an integrated hook, which allows suspension from chains, cables, or threaded rod. The 5-foot cord length provides flexibility for junction box positioning, and the 8-inch dimming cord is included for connection to 0-10V control circuits.

At 10 pounds, the fixture is manageable for single-person installation but still requires appropriate support hardware rated for the load. The black die-cast aluminum housing resists corrosion and handles the thermal demands of continuous operation in enclosed or semi-enclosed spaces.

The 50,000-hour L70 lifespan reduces lamp replacement cycles compared to metal halide. For facilities running extended shifts or continuous operations, this translates to years of use before output degrades to 70% of initial lumens.

How This Fixture Is Commonly Used

Once installed, the 0-10V dimming capability allows output adjustment based on daylight contribution, shift schedules, or task requirements. Facilities with building automation or standalone dimming controllers can reduce output during low-activity periods without fully de-energizing the fixture.

The 120-degree beam angle provides broad coverage from each mounting point. In high-ceiling applications, this spread reduces the number of fixtures needed to achieve uniform light distribution across open floor areas.

A motion sensor is available as an accessory for this fixture. When added, occupancy-based control is possible for aisles, storage zones, or areas with intermittent traffic.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The IP65 rating allows exposure to water jets and dust ingress without damage to internal components. IK10 impact resistance protects against physical contact equivalent to heavy tool drops or equipment bumps.

Surge protection is rated at 4kV, which provides a buffer against voltage spikes common in industrial electrical environments. The operating temperature range of -40°F to 113°F covers both refrigerated and non-conditioned spaces.

We back this fixture with a 5-year warranty.
