We renovated our master bathroom and have two of these above our vanity. We also have an LED fixture between the top of the mirrors and the ceiling, so the mirror light is not our only source of illumination. The only issue with installation is getting proper support (attaching to a stud, or setting a drywall anchor) and then leveling. The mirror is unforgiving if the support screws are not exactly level. But, once you get them on the wall, they work great. Ours have dedicated outlets for power, and have a light switch. We keep them powered, but the light turned off most of the time - so there is some phantom power use, but there is no delay with turning them on with a touch. I still use a makeup mirror with magnification, but the light from the mirror really brightens the vanity with a nice soft light.
