Performance & Light Output
This linear high bay provides massive, scalable illumination ranging from 51,000 to 60,000 lumens, achieving an ultra-efficient efficacy of up to 150 lumens per watt to easily replace 1000W+ traditional sources. The Opti-Select design allows installers to toggle between three distinct light distribution patterns (90x90°, 45x100°, or 65x95°), 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 large 27.6-inch 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).
