Exceptional features

The main value of Rang Dong’s smart color changing LED bulb is its ability to support both daily lighting and mood lighting.

Another important feature is Bluetooth Mesh connection. The technology allows the bulb to connect wirelessly and work with other compatible BLE devices. 

The system can be expanded with multiple smart devices, helping users build a more complete smart home lighting network. This Rang Dong product can be controlled through smartphone software compatible with Android and iOS. It also supports voice control through Google Assistant. 

Brightness can be adjusted from 10 percent to 100 percent to match different moments during the day. Users can create lighting scenes, control the lamp in real time, or set automatic schedules for switching, dimming and color changing. These features make the smart color changing LED bulb more convenient than using a traditional LED bulb.
