How is Miralight able to store and produce light?

The surface of Miralight has a material within its substrate which gathers and stores light energy on a sub-atomic level. Photons of light cause electrons in the atoms to move up to a higher orbit. In the absence of light energy, these same electrons fall from a higher energy level to a more stable energy level. When this occurs, they emit energy in the form of photons of visible light. No chemical reaction happens – it's all at the atomic level.

The wavelengths of light which are able to stimulate the electrons to a higher orbit are between 200-450nm. That is the upper part of the visible spectrum and ultraviolet. That's why light sources which contain ultraviolet light are better at charging Miralight; florescent lights, black lights and sunlight. Incandescent lights, like a typical light bulb, emit more light in the mid-to-lower range of the visible spectrum, so they are less efficient at charging. They still work, but take longer and it takes a stronger light.
