Used these lights to light up my nursery closet. They do not stick on their own. I had to use gorilla duct tape. There is enough spacing in between each LED that you can put a small strip of tape to reinforce it. This works great with Alexa. The app that it works with, you can control the color but cannot control the brightness. However, you can control the brightness with the Alexa app, also put it on a schedule. Pretty cool!
