Click the +/- button to select different brightness (10 levels, 10%-100%) to meet the lighting needs of different environments.Easy to Install: Using the pad double-sided adhesive included, you can stick the Hollywood makeup lamp on the mirror in minutes, simple and convenient. And since the length of the cable can be adjusted as needed, you can dress the mirror as you wish.
