Its basic only one or two years of life, work principle is in the state of a liquid lens material to add a transparent color factor, the factor with '300 ~ 450 nm wavelength ultraviolet (uv) and part of visible light and slow change color intensity, pervious to light degree is usually influenced by environmental temperature.
