This fog free, two-sided circular mirror has an 8.5-inch diameter that provides 1x and 8x magnification options to make sure every detail of your hair and makeup are in place. Both the hard-wired and plug-in models have a rotating on-off switch on the mounting plate. Illumination is by a "regular" 25-Watt incandescent bulb that works with the mirror design to yield a halo effect. The single extension arm will bring the mirror out to 13.5" from the wall and can be swiveled left-to-right quite easily as well as rotated at the mirror-base and flipped over in its yoke. Hardwired makeup mirrors should be installed by a licensed electrician. If near water both the mirror should be wired in conjunction with a GFI circuit. Overall Height - Top to Bottom: 14". Overall Width - Side to Side: 18.5". Overall Depth - Front to Back: 13.5". Overall Product Weight: 3.4 lbs.
