Lens & Optics

The field-adjustable optical system provides interchangeable aisle and open-area optics on the job site without tools or rewiring. The built-in beam selection switch allows installers to instantly toggle between three distinct distributions:

• 55° Narrow Optic: Concentrates beam distribution for narrow racking aisles, focused task areas, and elevated mounting heights.
• 85° Standard Optic (Pre-Installed): Delivers balanced distribution for standard warehouse floors.
• 105° Wide Optic: Delivers broad, uniform beam distribution for open warehouse floors, staging areas, and general open-ceiling commercial layouts.

Smart & Control Features

The RBAY22M/480 features an integrated sensor port supporting modular sensing and automated facility lighting control:

• 0–10V Continuous Dimming (Standard): Standard dimming control compatible with commercial 0–10V dimmers.
• Sensor Compatibility (Accessory): Accepts field-installable PIR and microwave occupancy sensors via the integrated sensor port.
• Lightcloud Blue (Accessory): Compatible with Bluetooth mesh controllers for wireless group control, automated scheduling, and occupancy sensing.

Compatible plug-and-play sensors include the PIR40, MVS50, PIR40/LCB, and MVS50/LCB — sold separately. Field sensor adjustments can also be managed using an optional handheld wireless remote (catalog # MSR1, sold separately).

Electrical

Powered by a Class 1 constant current driver operating on 480V AC at 50/60Hz. Delivers high electrical efficiency with a Power Factor >0.90 and Total Harmonic Distortion (THD) <20%. Integrated 6kV + 6kV surge protection protects internal electronics against line-to-line and line-to-ground transient voltage spikes. Includes pre-wired 0–10V dimming leads. RoHS compliant.

Construction

Housing & Thermal: Die-cast aluminum housing engineered with heat-dissipating fins. The housing functions as a high-efficiency passive heatsink, dissipating heat away from LED arrays and internal driver circuits to preserve lumen maintenance across the 100,000-hour rated lifespan.

Lens & Optics: Features a durable IK10 impact-resistant polycarbonate lens.

Finish: Commercial finish in White formulated for high durability and long lasting color.

Environmental Sealing: IP66 and IP69K rated and UL Listed for wet locations, providing a sealed barrier resistant to high-pressure washdown, dust, and moisture ingress. Ambient operating temperature range: −4°F (−20°C) to 122°F (50°C).

Dimensions & Weight: 23.88" L × 12.38" W × 3.75" H. Fixture weight: 12.43 lbs.
