I don't know what anyone else uses these lights for, but we used them in my husbands "man cave" or the den, as I call it. He put the app on his phone, and it was not long until these lights were changing colors, and just really cool to watch! He plays with them all the time. They were easy to put up, and trust me, if he can figure out how to work them with an app, anyone can. Really a great idea to change up any place, and make it look great.
