These lights look great and have good light. There are no problems. But now I've looked at 4 different recommended light switches posted on the Revain page and none of them can get rid of the hum. I've watched countless YouTube videos on how to do it right and get rid of the noise. But no matter which switch I set, it didn't go away. It's too late to return as I don't have the box, but I ended up getting another product in another room that didn't buzz. You may need to treat yourself and call an electrician as replacing 6 lightbulbs can be costly. Spring. It was worth trying.
