The 3x inset magnified mirror gives you all the information you need for detailed, up close grooming and the ribbon of light around the top and side of the mirror - 24" x 40" - bring task lighting exactly where you want it"¦..around your face. With a quick wave of your hand, the motion sensor under the lower right edge of the mirror turns the light on and off. Hold your hand under that same motion sensor and the tunable light around the edge and around the magnified inset will slowly change from warm white (2700 kelvin) to cool white daylight (6000 kelvin).
