I bought these for my husband's man cave. The lighting is a bit poor because it's only a basement, but this was an easy fix. With an existing light fixture, all you have to do is screw it in like a regular light bulb. My husband ended up installing them in places that didn't already have brackets, but it was easy enough that he did it himself and didn't have to call an electrician. I love that we can change the color to suit our mood and brighten or matte as needed. The app is very user friendly which is a relief for people like me who are not very tech savvy. You can change the color or brightness and even set the routines within the app.
