I bought these for fan use and they fit perfectly. They came with easy to follow instructions. You need to download their app and connect the light to your wifi and then you can connect to Google Home or Alexa. For some reason they wouldn't connect to the wifi, it took about 5 tries for each bulb to connect and it kept saying "timed out" then finally it suddenly connected for no reason. This part was a bit disappointing because there didn't seem to be any reason why they were having connection issues. Also, one of the lights has a delay, the other two lights change color or dim, then one delays about a second before continuing. You don't notice it unless you look at it directly, so it's not a problem, just wanted to mention it. 5 stars because overall they were easy to install, took a while to connect and worked great with my Google home. Very easy to set up and great price.
