The simplehuman sensor mirror lights up automatically. Its tru-lux light system simulates natural sunlight, allowing you to see full color variation, so you'll know when your makeup is color-correct and flawless. Unlike traditional vanity makeup mirrors' bulb lighting, simplehuman's long-lasting LEDs won't burn out or diminish. The mirror folds down flat and stores easily in its travel case. Recharges with a standard Usb port (cable included), and one charge lasts up to 5 weeks. The distortion-free mirror has 10x magnification - ideal for close-up work like tweezing or eyeliner and lipstick application. It folds up and stores easily in the included padded travel case.
