270 / 340 / 400 Wattage Adjustable High Bay Linear | 41600 to 54100 Lumens | 4000K / 5000K Adjustable | 100-277V | 3 Foot 8 Inches

Product Overview

This adjustable LED UFO high bay delivers 22,500 to 36,000 lumens at 150 watts per lumen efficiency, with field-selectable wattage at 150, 200, or 240 watts. Color temperature is adjustable between 4000K and 5000K. The fixture operates on 100-277V input at 50/60 Hz and includes 0-10V dimming capability.

Construction uses die-cast aluminum housing with a polycarbonate lens and a standard 120-degree beam angle. The fixture measures 12 x 7.8 inches and weighs 7.5 pounds. A 5-foot power cord and 8-inch dimming cord are included. Housing is available in black or white.

This fixture replaces 400 to 1000 watt metal halide systems. Rated lifespan is 50,000 hours at L70. The fixture is UL listed and DLC Premium qualified.

Where This Product Fits Best

The IP65 rating allows installation in spaces exposed to dust accumulation and water spray from any direction. The IK10 rating provides resistance to physical impact, suitable for environments where equipment movement or material handling creates risk of contact with the fixture.

Operating temperature range spans -40°F to 122°F, supporting installation in cold storage facilities, unconditioned warehouses, and spaces with significant seasonal temperature variation. The 6kV surge protection addresses electrical transients common in industrial environments with heavy motor loads or inconsistent power quality.

Voltage compatibility from 100V to 277V covers standard commercial and industrial electrical systems without requiring voltage-specific fixture selection.

Performance and Functional Considerations

Lumen output scales with wattage selection: 22,500 lumens at 150 watts, 30,000 lumens at 200 watts, and 36,000 lumens at 240 watts. All three settings maintain 150 lumens per watt efficiency. CRI is 80+, providing accurate color rendering for general warehouse, manufacturing, and distribution applications.

The 120-degree beam angle provides broad coverage appropriate for high-ceiling installations where wide light distribution is needed. The polycarbonate lens contributes to durability while maintaining optical clarity.

The 0-10V dimming input allows integration with compatible dimming controls and building management systems. The 8-inch dimming cord provides connection access without requiring field wiring modifications inside the fixture housing.

Installation and Long-Term Use

Mounting options include hook and pendant configurations. The 5-foot power cord length accommodates typical high bay installation scenarios where junction boxes or conduit connections are positioned above the mounting point.

At 7.5 pounds, the fixture weight is manageable for single-person installation in most hook-mount applications. The 12 x 7.8 inch footprint allows placement in standard grid patterns without interference from structural elements in most ceiling configurations.

Die-cast aluminum housing dissipates heat effectively over the 50,000-hour rated lifespan. The combination of IP65 and IK10 ratings reduces long-term maintenance exposure in demanding environments where fixtures are subject to contamination or physical contact.

How This Fixture Is Commonly Used

Facilities use the wattage selector to match output to ceiling height and task requirements after installation. A maintenance lead can adjust from 150 to 240 watts without tools or rewiring if light levels need to change due to racking reconfiguration or process changes on the floor.

The color temperature switch between 4000K and 5000K allows adjustment based on application. Operators often select 5000K for inspection areas or spaces requiring visual acuity, while 4000K suits general warehouse aisles or areas where warmer light is preferred.

The 0-10V dimming connection integrates with existing building automation or standalone dimmer switches. Facilities with daylight harvesting systems or occupancy-based controls use this input to reduce output during low-activity periods or when ambient light is sufficient.

A motion sensor is available as an accessory for installations requiring occupancy-based control. The hook and pendant mounting options accommodate different ceiling types and structural attachment points encountered across warehouse, manufacturing, and distribution environments.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The 6kV surge protection rating addresses transient voltage events. IP65 and IK10 ratings define environmental and impact resistance.

We provide a 5-year warranty on this fixture.
