155 / 180 / 210 Wattage Adjustable High Bay Linear | 22880 to 31000 Lumens | 4000K / 5000K Adjustable | 100-277V or 277-480V | 1 Foot 2 Inches

Product Overview

This linear high bay fixture delivers selectable output from 22,880 to 31,000 lumens across three wattage settings: 155W, 180W, and 210W. At 150 lumens per watt, the fixture is designed to replace 400W or 1000W metal halide systems in high-ceiling industrial and commercial environments.

Color temperature is field-adjustable between 4000K and 5000K. Two voltage configurations are available: 100-277V and 277-480V. The fixture measures 14 x 11.5 x 2.1 inches, weighs 7 pounds, and ships in a white finish with a polycarbonate lens and 90-degree beam angle.

Construction is die-cast aluminum housing with 10kV surge protection. The fixture operates from -40°F to 122°F, carries a CRI of 80+, and is rated for 50,000 hours at L70. Dimming is supported via 0-10V protocol.

Where This Product Fits Best

This fixture is intended for indoor industrial and commercial spaces with existing metal halide high bays in the 400W to 1000W range. The compact 14-inch form factor and 7-pound weight allow it to fit into tighter structural layouts or between existing infrastructure where larger fixtures would not clear.

The operating temperature range of -40°F to 122°F supports use in cold storage entryways, unheated warehouse bays, and facilities with elevated ambient temperatures from machinery or processes. The 10kV surge rating provides protection in environments with electrical noise from motors, compressors, or welding equipment.

Two voltage versions accommodate both standard 100-277V commercial service and 277-480V industrial distribution, which determines fixture selection based on the site''s available supply.

Performance and Functional Considerations

The three-step wattage selector allows output to be matched to mounting height and task requirements. At 155W, the fixture produces 22,880 lumens. At 180W, output is 26,570 lumens. At 210W, output reaches 31,000 lumens. All three settings maintain 150 lumens per watt.

The 90-degree beam angle and polycarbonate lens produce broad, even distribution suited to open floor areas. This is a fixed optic?there are no interchangeable reflectors or lenses.

Color temperature is adjustable between 4000K and 5000K. The 4000K setting produces a neutral white appearance. The 5000K setting produces a cooler, daylight-balanced output. Both settings maintain 80+ CRI for accurate color rendering across general industrial tasks.

Installation and Long-Term Use

Mounting options include chain or cable suspension as standard, with pendant and surface mounting also supported. The fixture ships without a cord, so field wiring is required. At 7 pounds, the fixture can typically be supported by standard high bay mounting hardware.

The die-cast aluminum housing manages heat dissipation and provides structural rigidity. The 50,000-hour L70 lifespan establishes the expected duration before output declines to 70% of initial lumens. Power factor is 0.90 with THD at 20% max, which supports electrical compatibility on shared circuits.

An optional emergency backup battery is available. A motion sensor is also available; a remote control is required to change default sensor behavior and one remote is typically needed per project.

How This Fixture Is Commonly Used

The wattage and color temperature adjustments are typically set during installation based on ceiling height, task type, and visual preference. Once configured, these settings remain fixed unless the fixture is accessed again for adjustment.

Facilities replacing metal halide systems often use the wattage selector to dial in output after install, increasing or decreasing brightness based on actual conditions rather than relying solely on pre-installation calculations. The color temperature switch allows matching to adjacent fixtures or adjusting to worker preference without replacing the unit.

The 0-10V dimming input allows integration with external control systems for scheduled dimming or occupancy-based response. Where motion sensing is installed, the fixture responds to presence and returns to standby levels after the configured hold period.

Safety, Certifications, and Warranty

This fixture is UL listed and DLC Premium qualified. The 10kV surge protection rating supports deployment in environments with transient electrical events. Operating temperature range is -40°F to 122°F.

We provide a 5-year warranty on this fixture.
