4FT LED Linear High Bay Light, 165W-300W Selectable, 50,400LM, 6CCT, 0-10V Dimmable, 120-277V, IP65, DLC Premium

4FT LED Linear High Bay Light with 165W-300W Selectable Power

Designed for high-output commercial and industrial lighting applications, this 4FT LED Linear High Bay Light combines five selectable wattage settings, six selectable color temperatures, high-efficiency LED performance, and standard 0-10V dimming in one versatile G1 series fixture.

The fixture can be field adjusted to 165W, 200W, 225W, 255W, or 300W, giving contractors, facility managers, and commercial lighting professionals greater flexibility when specifying lighting for warehouses, manufacturing facilities, distribution centers, gymnasiums, workshops, and other large high-ceiling spaces.

With luminous efficacy up to 168 lm/W, the fixture delivers up to 50,400 lumens at the maximum 300W setting. Six selectable color temperatures— 3000K, 3500K, 4000K, 5000K, 5700K, and 6500K— allow the light appearance to be adjusted during installation for different commercial and industrial environments.

High-Output 50,400-Lumen Performance

With output up to 50,400 lumens and efficacy up to 168 lm/W, this 4FT linear high bay is designed for applications requiring substantially higher illumination than lower-wattage commercial high bay fixtures.

The high-output design is particularly suitable for large open floor areas, manufacturing environments, distribution facilities, storage areas, and other high-ceiling spaces where strong and broadly distributed illumination is required.

Five Selectable Wattages in One Fixture

The integrated wattage selector allows installers to choose 165W, 200W, 225W, 255W, or 300W during installation. This helps one fixture platform accommodate multiple project requirements without specifying a separate fixed-wattage model for every lighting level.

*Reference outputs for lower wattage settings are calculated using efficacy up to 168 lm/W. Actual delivered lumen output may vary by configuration and operating conditions.

6CCT Selectable for Commercial & Industrial Projects

The integrated color temperature selector provides 3000K / 3500K / 4000K / 5000K / 5700K / 6500K in one fixture, allowing contractors to select the appropriate light appearance during installation.

• 3000K: Warm white illumination.
• 3500K: Warm-neutral commercial lighting.
• 4000K: Neutral white for commercial and industrial spaces.
• 5000K: Daylight white commonly used in warehouses and work areas.
• 5700K: Cool daylight for high-visibility environments.
• 6500K: Cool white for applications requiring a brighter visual appearance.

Wide 120° Light Distribution

The 120° beam angle and 4FT linear luminous surface provide broad light distribution across large spaces. This design helps illuminate aisles, production floors, storage areas, workshops, and open commercial environments with wide coverage.

Flexible Mounting Options

Chain mounting is standard for suspended high-bay installations. Pendant and surface mounting options are also available, allowing the fixture to accommodate different ceiling structures and commercial installation requirements.
