I needed some lights for my vanity , however did not want anything that I would need an electrician to install for me. These lights are amazing , I read one review where it said to be careful while applying foundation/makeup because of the glow of the light. I have to disagree, I needed these lights specifically for applying my makeup in the morning, and to me the lighting is perfect. "Now as for the dimming" not so much dimming in my opinion , I mean its either bright or dark lol , either way I still give these 5 stars and would recommend to anyone. BTW it fit my mirror perfect , not sure of the dimensions of my mirror , but I was able to wrap the entire light set around my mirror, I did not need extra , nor did i have to cut off any strips. "my mirror is pretty much the size of the picture. also very easy to install!! Great Product thanks :) Its been a week since I have had them hopefully they continue working great!
