Zhaga Book 18 & NEMA Control Receptacles
Commercial exterior luminaires are increasingly specified with standardized ANSI C136.41 7-pin NEMA or Zhaga Book 18 sockets. This modularity permits plug-and-play installation of photocells, microwave motion sensors, and wireless mesh nodes (Zigbee, Bluetooth Mesh, Silvair) without compromising the IP66 sealed optical chamber.
