175 / 195 / 225 Watts Adjustable Linear LED High Bay | 26250 to 33750 Lumens | 4000K / 5000K Adjustable | 100-277V | 3 Foot 8 Inches

Product Overview

This 3-foot-8-inch linear LED high bay delivers field-adjustable output from 175 to 225 watts, producing 26,250 to 33,750 lumens at 150 lumens per watt. The fixture replaces 400-watt and 1000-watt metal halide systems and operates on 100-277V input at 50/60 Hz.

Color temperature is selectable between 4000K and 5000K. The fixture includes a frosted lens with a 120-degree beam angle and supports 0-10V dimming. CRI is rated at 80+.

Construction is die-cast aluminum with a white finish. The fixture measures 44.3 x 12.6 x 3 inches and weighs 11 pounds. Standard mounting is chain-cable suspension. No cord is included.

Where This Product Fits Best

This linear high bay is built for spaces currently running 400-watt or 1000-watt metal halide fixtures where a direct reduction in energy use and maintenance frequency is needed. The adjustable wattage range allows the same fixture to serve varying mounting heights or light level requirements across a facility.

The operating temperature range of -40°F to 113°F supports use in cold storage entries, unheated warehouses, and temperature-controlled manufacturing areas. The 6kV surge protection handles electrical transients common in industrial electrical environments.

Facilities using 0-10V dimming infrastructure can integrate this fixture directly. The 100-277V input range covers standard commercial and industrial electrical systems without requiring transformers or voltage matching.

Performance and Functional Considerations

Output ranges from 26,250 lumens at 175 watts to 33,750 lumens at 225 watts. Efficiency holds steady at 150 lumens per watt across all wattage settings. This consistency allows adjustments based on actual light level needs without sacrificing efficiency.

The 120-degree beam angle from the frosted lens produces broad, even light distribution suited to open floor areas. Color rendering at 80+ CRI supports general industrial tasks and visual inspection work where accurate color perception matters.

Power factor is rated at 0.90 with total harmonic distortion at 20% maximum. Rated lifespan is 100,000 hours at L70, meaning the fixture retains 70% of initial output at that point.

Installation and Long-Term Use

The fixture ships without a cord and mounts using chain or cable suspension as standard. At 11 pounds, it handles like typical linear high bays during installation. Physical dimensions are 44.3 inches long, 12.6 inches wide, and 3 inches deep.

Wattage and color temperature are adjustable on the fixture, allowing settings to be confirmed or changed at installation or during future maintenance without replacing hardware. The die-cast aluminum housing supports long-term use in demanding environments.

A motion sensor is available. Adjusting motion sensor settings requires a remote control, with one remote needed per project. The fixture connects to 0-10V dimming systems for integration with building lighting controls.

How This Fixture Is Commonly Used

Facilities use the wattage selector to match output to actual conditions once the fixture is in place. A space with higher ceilings or darker surfaces may run at 225 watts, while the same fixture in a lower bay or lighter-finished area can be set to 175 watts. This adjustment happens on the fixture itself.

The color temperature switch allows crews to select 4000K for areas where a warmer tone is preferred or 5000K where a cooler, higher-contrast appearance is needed. Both settings are accessible without tools after installation.

When connected to 0-10V dimming, the fixture responds to building automation or manual dimmers for scheduled dimming, daylight response, or energy management routines. The motion sensor option adds occupancy-based control for areas with intermittent traffic.
