The system consists of up to 50 bulbs, a networking hub, and a smartphone app. After screwing in the bulbs, users connect the hub to their router via an Ethernet cable. The hub communicates with the bulbs through the ZigBee wireless transmission standard and with the owner's phone over Wi-Fi. The hub sends signals from the app to turn lights on and off, set timers, and control brightness and color. The bulbs can also relay signals to one another, which extends the hub's initial 200-foot range to cover an entire home.
