Lens & Optics

The Field-Adjustable optical system provides interchangeable aisle and open-area optics on the job site without tools or rewiring:

• 90x90° Standard Optic: Delivers broad, uniform beam distribution for open warehouse floors, staging areas, and general open-ceiling commercial layouts.
• 45x110° Aisle Optic: Concentrates beam distribution for narrow racking aisles, focused task areas, and elevated mounting heights.

Optics are swapped by simply rotating the lens assembly 180 degrees.

Smart & Control Features

The RBAY15S features an integrated low-voltage control receptacle supporting modular sensing and automated facility lighting control:

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

Compatible plug-and-play sensors and the MSR1 remote are 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) <10%. Integrated 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.

Operating current and amp draw across input voltages for branch circuit and breaker loading calculations:

Construction

Housing & Thermal: Aluminum housing engineered with radial convection cooling 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: Polycarbonate lens platform. See Lens & Optics section above for beam spreads and swap procedures.

Finish: Commercial powder-coat finish in White formulated for high resistance against corrosion and surface wear in demanding industrial facilities.

Environmental Sealing: IP20 rated and UL Listed for damp locations, providing a barrier against solid objects. Ambient operating temperature range: -40°F (-40°C) to 122°F (50°C).

Dimensions & Weight: 14.125" L × 10.625" W × 2.125" H. Fixture weight: 4.4 lbs.

Installation & Mounting

Standard Hardware: Ships standard with V-hooks for chain suspension installation.

Mounting Options: Compatible with rigid pendant mounting and direct surface mounting via dedicated bracket accessories.

Wiring: Includes pre-wired 0–10V dimming leads.
