A 40 cm lit mirror that runs six hours off its own battery. Switch between warm, daylight and cool white so your makeup matches the light you will actually be seen in. Three colour temperatures: Warm at 3000K, daylight at 4500K and cool at 6500K, so you can apply makeup under daylight and check how it reads under warm evening light. 6 hours cordless: A 5000 mAh battery runs a full session and beyond, or plug it in and use it corded, so it works on a dressing table or in a hotel room with no socket nearby. Memory function: Comes back on at the brightness and tone you last used, so you are not resetting it every morning. 360 degree rotation: Turns to any angle, so you can tilt it for close work or angle it toward a window without moving the whole mirror. Specifications Diameter: 40 cm Battery: 5000 mAh, up to 6 hours Charging: USB rechargeable, also works plugged in Colour temperatures: 3000K warm, 4500K daylight, 6500K cool Controls: Touch, dimmable, memory function Rotation: 360 degrees Use the 4500K daylight setting for applying makeup, since it comes closest to natural light and is the best guide to how the result will look outdoors. Set it on a dressing table or take it away with you, and switch tones to match the light you will be seen in.
