Yes, when you turn off by the wall switch, all parts of this mirror include the light will not work. It is energy saving, and there is a anti-fog button to turn off the anti-fog function.

Hi,

When the power off, the vanity mirror will off, including the light and the button can't work too.

That means if you turn off the wall switch, the buttons on the mirror and the whole light will not glow

Don't worry, this led bathroom mirror is very energy-saving.

Hope this is helpful.

Unfortunately if you turn on the wall switch again the whole light will not glow, only the button. You have to get to the mirror and touch it. If you dimmed mirror before switching the wall switch it will not keep the settings.
