I got these lights to go around my son’s computer desk and they look so cool! They’re about 6 1/2 ft long and fit perfectly around his desk. He turns them on while he’s gaming and he likes that he can change the colors and modes with a small remote. They were simple  to attach with the small screws and clips, but I imagine it wouldn’t be as simple to attach them to sheet rock as the screws are tiny. We only have one strand so if we were to add another, it doesn’t look like they’d connect to each other so that’s something to keep in mind if you’re looking to string them together.
