Smart & Control Features

The RBAY17M/E 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 120-277V 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: Low-profile, lightweight die-cast aluminum 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 polycarbonate lens and polycarbonate reflector engineered to guarantee light intensity and uniformity.

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

Environmental Sealing: IP20 rated and UL Listed for damp locations, providing a sealed barrier resistant to dust ingress. Ambient operating temperature range: 32°F (0°C) to 113°F (45°C).

Dimensions & Weight: 19.69" L × 11.81" W × 2.06" H. Fixture weight: 6.53 lbs.
