Smart & Control Features

The AEROBAY supports advanced automated facility lighting control via the Lightcloud Blue ecosystem:

• 0–10V Continuous Dimming (Standard): Standard dimming control compatible with commercial 0–10V dimmers.
• Lightcloud Blue Installed (Accessory): Optional factory-installed Bluetooth Mesh controller provides Luminaire-Level Lighting Control (LLLC) including wireless switching, high-end trim configuration, and occupancy sensing. Utilizes a secure Bluetooth Mesh network eliminating the need for a gateway or hub.

Electrical

Powered by a 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) <11%. Integrated 6kV surge protection protects internal electronics against transient voltage spikes. Includes pre-wired 0–10V dimming leads. RoHS compliant.

Construction

Housing & Thermal: Aluminum housing engineered to function 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 Polyethylene Terephthalate (PET) reflector.

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

Environmental Sealing: UL Listed for damp locations. Ambient operating temperature range: −4°F (−20°C) to 122°F (50°C).

Dimensions & Weight: 36.00" L × 10.00" W × 2.50" H. Fixture weight: 9.5 lbs.
