Using the Sun as their template, humans developed artificial sources of light. Each new generation of lighting technology came closer and closer to replicating the various types of light radiated by Earth’s parent star. Today, the versatility of LEDs allow them to serve as pocket suns under the complete control of their creators – and they can do much more in the future....read more>>>...
