HappyLighting is a free Android app developed by qh-tek that allows you to control your Bluetooth lamps. With this app, you can match the colors of your HappyLighting Bluetooth lights, control their timing, set the lighting mode, and even change the color of the light according to the music you're playing.

It's worth noting that HappyLighting only supports Bluetooth lamps that start with "Triones, BRGlight, Dream, Light" in the Bluetooth list. If your Bluetooth lamp doesn't meet this requirement, then this app won't be useful for you.

Overall, HappyLighting is a great app for those who want to control their Bluetooth lamps with ease and convenience. With its simple and user-friendly interface, you can easily adjust the settings of your lamps according to your needs.
