Light creates images and as such the quality of any image will be greatly determined by the volume of light it can absorb and reflect. Every form of light has their unique capacities and effects on the images the fall upon. The sun for instance is a light source that both produces light as well as heat. The sun can generate more than one form of energy because of it's uniqueness amongst others in the community of lights.
Light reveals, and the color of light determines what is revealed, for some reason all lights are not equal in illumination, even the Holy Bible teaches that the stars differ in glory, and there is one glory of the sun, another of the moon and stars
