Performance & Light Output

The SYLVANIA 66439 delivers scalable illumination from 26,250 to 33,000 lumens, achieving up to 150 lumens per watt — providing up to 73% energy savings over traditional 250W–400W 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 120–347V universal 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 commercial environments, the luminaire features a durable white steel housing with an 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.
