320 / 400 / 500 Watt Adjustable Linear LED High Bay Light | 48960 to 76900 Lumens | 3500K / 4000K / 5000K Adjustable | 100-277V | 3 Foot 4 Inches

Product Overview

This 175/195/225 watt adjustable linear LED high bay measures 44.3 inches long by 12.6 inches wide by 3 inches deep and weighs 11 pounds. The fixture replaces 400 to 1000 watt metal halide systems and operates on 100-277V input at 50/60 Hz. Output ranges from 26,250 to 33,750 lumens depending on wattage selection, maintaining 150 lumens per watt across all settings.

Wattage and color temperature are field-adjustable. Wattage options are 175, 195, and 225 watts. Color temperature options are 4000K and 5000K. The fixture uses a frosted lens with a 120-degree beam angle and delivers 80+ CRI. Dimming is 0-10V compatible.

Construction is die-cast aluminum with a white finish. The fixture includes 6kV surge protection and operates in ambient temperatures from -40°F to 113°F. Rated lifespan is 100,000 hours at L70. Standard mounting is chain or cable suspension. The fixture ships without a power cord.

Where This Product Fits Best

This linear high bay fits applications where 400 to 1000 watt metal halide fixtures are currently installed or specified. The 26,250 to 33,750 lumen output range and adjustable wattage allow a single fixture to address varying ceiling heights and light level requirements within a facility.

The 100-277V input handles standard commercial and industrial electrical systems. The -40°F to 113°F operating range supports cold storage entries, unconditioned warehouses, and manufacturing spaces with elevated ambient temperatures. The 6kV surge protection is appropriate for environments with electrical noise from motors, compressors, or other industrial loads.

At 44.3 inches long, the linear form factor works in aisle-oriented layouts and spaces where directional coverage along a run is more useful than radial distribution from a compact source.

Performance and Functional Considerations

Lumen output scales directly with wattage selection: 175 watts produces 26,250 lumens, 195 watts produces 29,250 lumens, and 225 watts produces 33,750 lumens. Efficacy remains constant at 150 lumens per watt regardless of setting. This allows output adjustment without efficiency loss.

The 120-degree beam angle from the frosted lens provides broad coverage suited to general area lighting. CRI of 80+ is adequate for most warehouse, manufacturing, and distribution environments where color accuracy is a secondary consideration to light level and uniformity.

Power factor is 0.90 and total harmonic distortion is 20% maximum. These values are typical for commercial LED high bays and should not create issues with standard building electrical systems.

Installation and Long-Term Use

The fixture mounts using chain or cable suspension as standard. At 11 pounds and 44.3 inches in length, two-point suspension is typical for stability. No power cord is included, so field wiring is required.

Wattage and color temperature adjustments are made at the fixture. This allows output and color to be set during installation based on actual conditions rather than predetermined at time of order. Adjustments can also be made later if space use or requirements change.

The 100,000-hour L70 lifespan reduces relamping frequency compared to metal halide systems. Die-cast aluminum construction and 6kV surge protection support long-term reliability in demanding environments.

How This Fixture Is Commonly Used

In day-to-day operation, this fixture is typically set once during installation and left alone. The wattage and color temperature selections are made based on ceiling height, task requirements, and preference. Most facilities set it and do not revisit the adjustment unless space use changes significantly.

The 0-10V dimming input allows integration with building controls or standalone dimmers where variable output is needed during different shifts or operations. A motion sensor is available as an accessory for occupancy-based control.

Facilities replacing metal halide systems often adjust wattage upward in areas with higher ceilings or more demanding visual tasks, and downward in areas where full output is unnecessary. The ability to make this decision after the fixture is in place avoids the need to predict exact requirements in advance.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. We provide a 5-year warranty.

The operating temperature range of -40°F to 113°F defines the ambient conditions the fixture is rated to tolerate. The 6kV surge rating indicates the fixture can withstand transient voltage spikes up to that level without damage.
