Love these, they are very well made. I purchased 3 to hang on our outside  garage lights. I almost returned them because I was not sure how to hang them (not a handy person). I just used wire and they look amazing. You just turn the lights on once to set the timer, at the time you want them to start, and it is set going forward. They are on for 6 hours and then off for 18 hours. I have received many compliments.
