Performance & Light Output
The SYLVANIA 66445 delivers scalable illumination from 51,000 to 60,000 lumens, achieving up to 150 lumens per watt — providing significant energy savings over traditional 1,000W–1,500W HID sources. The Opti-Select design lets installers toggle between three distinct light distribution patterns (90x90°, 45x100°, or 65x95°), making it easy to switch between wide open-area lighting and narrow aisle lighting directly on the job site. LEDs deliver a CRI greater than 80 and an L70 rated life of 100,000 hours.
Electrical & Controls
This fixture operates on a 277–480V high-voltage AC driver at 50/60Hz with standard 0–10V dimming. Power factor exceeds 0.9 and total harmonic distortion (THD) is below 20%. All fixtures ship with a pre-wired sensor base ready to accept an optional screw-in motion/daylight sensor (sold separately) or field-installable LEDVANCE LINK Bluetooth Mesh network components for advanced lighting controls.
Construction & Durability
Engineered for demanding industrial environments, the 27.6-inch luminaire features a durable white steel housing with a polycarbonate lens and IK09 impact rating. The cULus Damp Location listing ensures reliable operation in ambient temperatures from –40°C to 50°C (–40°F to 122°F) — suitable for cold storage, loading docks, and outdoor-adjacent spaces.
