Lightcloud

Lightcloud Blue Installed

Lightcloud Blue, RAB's wireless lighting control system, eliminates the need for a hub or controller. The app shows the fixtures nearest you first, so an area is set up in minutes, even without internet on site. Lights and schedules keep working if the Wi-Fi goes down, and a Nano adds control from anywhere.
DLC system: N1XMLOEATBA (Interior); NHCZ2BIA17L (Exterior)
