Artificial lighting can come from a variety of sources such as lamps, lightbulbs, and candles. The invention of lighting has had far-reaching effects on society. It has allowed people to work better and longer and usher in a new era of production and development.

Modern lighting technologies allow us to maximize the potential of light, to increase visibility and to create a desired atmosphere.
