Performance & Light Output

This linear high bay provides highly scalable illumination ranging from 26,250 to 33,000 lumens, achieving an ultra-efficient efficacy of up to 150 lumens per watt to provide significant energy savings over traditional sources. The Opti-Select design allows installers to toggle between three distinct light distribution patterns (90×90 , 45×100 , or 65×95 ), making it incredibly easy to switch between wide open-area lighting and narrow aisle lighting directly on the job site. The LEDs deliver a color rendering index (CRI) greater than 80 and maintain a heavily prolonged L70 rated life of 100,000 hours.

Electrical & Controls

This fixture operates on a dedicated 277-480V AC driver with standard 0-10V dimming functionality. The electrical components maintain a power factor greater than 0.9 and total harmonic distortion (THD) below 20%. To maximize energy savings and simplify inventory management, all fixtures are shipped with a pre-wired sensor base. This base is ready to accept an optional screw-in motion/daylight sensor (sold separately) or field-installable LEDVANCE LINK Bluetooth Mesh network components.

Construction & Durability

Engineered for tough commercial environments, the luminaire features a durable white housing with an IK09 impact rating to protect against physical strikes. It carries a cULus Damp Location listing, ensuring reliable operation in ambient temperatures ranging from -40 C to 50 C (-40 F to 122 F).

Installation & Mounting

The high bay is designed for straightforward suspended mounting right out of the box, with V-hooks and 3-foot mounting chains included. For customized site applications, optional surface mounting brackets, pendant mounting brackets, and aircraft cable mounts are available (sold separately).
