180 / 240 / 300 Watt Adjustable LED Indirect High Bay Light | 25200 to 42000 Lumens | 4000K / 5000K | 100-277V | 3 Foot

Product Overview

This 3-foot indirect LED high bay delivers upward-directed light using a frosted polycarbonate lens, producing soft, diffused illumination without the harsh glare typical of direct-mount fixtures. The fixture operates at 180, 240, or 300 watts with corresponding outputs of 25,200, 33,600, or 42,000 lumens, all at 140 lumens per watt. Wattage and color temperature are field-selectable, allowing configuration at the time of installation.

The fixture replaces 250 to 400 watt metal halide systems and accepts 100-277V input at 50 or 60 Hz. Color temperature options are 4000K and 5000K, with a CRI of 80+. A 90-degree beam angle provides broad upward distribution from the indirect orientation. The housing is white, and standard mounting is chain or cable suspension.

Where This Product Fits Best

Indirect high bays are used where visual comfort matters as much as light level. Spaces with exposed ceilings, open office layouts beneath high decks, retail environments, or areas where occupants look upward benefit from the softer distribution this fixture produces. The upward throw bounces light off ceilings or structures, reducing direct glare and harsh shadows.

The operating temperature range of -22°F to 122°F supports use in climate-controlled interiors and unconditioned spaces that stay within those limits. The 3-foot form factor fits well in linear layouts or where architectural alignment with ceiling features is needed. This fixture is not suited to environments requiring downlight focus or narrow beam control.

Performance and Functional Considerations

The three wattage settings provide flexibility during installation to match output to ceiling reflectance and space requirements. At 300 watts, the fixture produces 42,000 lumens, appropriate for higher ceilings or darker ceiling surfaces that absorb more light. Lower wattage settings reduce output proportionally and may suit spaces with lighter, more reflective surfaces.

The frosted polycarbonate lens diffuses the LED source, eliminating visible point glare from below. This is a defining characteristic of indirect fixtures and makes them appropriate for environments where occupants are sensitive to overhead brightness. The 0-10V dimming input allows integration with building lighting controls or manual dimmers for output adjustment after installation.

Rated lifespan is 150,000 hours at L70, meaning the fixture will maintain at least 70 percent of initial output through that duration under normal operating conditions.

Installation and Long-Term Use

The fixture ships without a cord and mounts via chain or cable, which is standard for suspended indirect applications. Physical dimensions are 35.4 inches by 11.5 inches by 2 inches, with a weight of 7.3 pounds. The lightweight housing simplifies rigging and reduces load on ceiling structure or support points.

Field-selectable wattage and color temperature are configured at install, allowing a single fixture to be adapted to application needs without separate models. Once installed, the fixture can be dimmed using any compatible 0-10V control signal. The 100-277V input range covers standard commercial voltages in North America without requiring transformers or voltage-specific models.

How This Fixture Is Commonly Used

Facilities typically deploy this fixture where ceiling-bounce lighting creates a more comfortable environment than direct downlighting. The field-selectable wattage lets installers tune output based on observed conditions at the site, especially where ceiling color or height varies across zones. Once set, output remains fixed unless the fixture is accessed again.

The 0-10V dimming connection allows ongoing adjustment through a building''s lighting control system or a simple wall-mounted dimmer. This is often used to reduce output during daylight hours or in response to occupancy levels. The 4000K and 5000K color options are selected based on the visual tone preferred for the space, with 4000K offering a warmer appearance and 5000K a cooler, more clinical look.

Safety, Certifications, and Warranty

This fixture is ETL listed and DLC Premium qualified. The 5-year warranty is provided by LED Lighting Supply and covers manufacturing defects under normal use conditions.
