This mirror was very easy to install. The brackets screw onto the wall at the height you want to place it, and the lip of the mirror sit on them. We were able to remove our current light fixture, because this mirror does a great job, and we also hsve a 2nd light in there if needed. You can dim this light to use as more of a nightlight as well. You can control woth the switch once you hardware it, or with touch panel on the mirror itself. I love the update this gave!
