Using sound to control the light bulb has been widely used in various corridors. It can be turned on for a while at night as long as there is a sound. Hey, the light is an LED bulb that can interpret digital sound. It uses sound as the control mode. It uses a sound with a duration of less than 1 second, like chirping, chirping and birdsong. It is encoded into dozens of different instructions. It sounds like each sound is not different, but it is different instructions, such as switching, lightening, darkening, color switching and other operations. The bulb that can be controlled without WiFi/Bluetooth/Zigbee is what users really need.

Packaging

The front side of the package of HEILIANG is LOGO, and the light bulb is painted very vividly. The main body adopts black color because the light is white, which represents light, and highlights the role of the light.
