Yeelight sunflower is a wireless, smart, scene lighting system. It can be installed into your home Wi-Fi network, and all the bulbs form a system with control box automatically. You may control the bulb to change their color and brightness with smart device such as smart phone or pad, also you may save the setting to a scene and recall it at next time. Now the app supports iOS version 5.0+ and Android 2.3.3+.
For the starter pack, there are 3 yeelight bulbs and 1 control box; it is the base lighting system.
The yeelight sunflower bulb is a LED lighting bulb, in which there is a wireless sending/receiving component working via Zigbee signals. The bulb receives signals from control box and changes color and brightness to what you want.
The control box is a LAN (local area network) to Zigbee Bridge, which transforms the smart phone control commands (Wi-Fi signals) to Zigbee signals. The control box has one LAN socket, with which it can be connected to your home Wi-Fi AP. When it boots up, an IP address will be assigned and your smart phone can search and connect to it via Wi-Fi.
