Lighting is an essential part of the human experience. Whether you're inside a residential dwelling or outside in the middle of the night, a source of light can make everything from a dark room to an unlit landscape seem both safer and more inviting. The development of light sources has been a part of human history since ancient times. Natural light sources, such as fire and the sun, were the primitive versions of what we now rely on. As electricity became readily available in the 19th century, kerosene lanterns, gas lamps, and electric bulbs could be added to the list. The potential of light has grown with the opportunities. Architectural lighting, stage lighting, and decorative lighting have become staples of indoor dwelling. Flood and traffic lights, as well as street lighting, are vital to outdoor living, providing guidance and visibility during a night commute or a midnight walk. Technological advances in light sources and performance has pushed forward the possibilities for at-home lighting users. From lamps to LED panels, each lighting source gives off a different glow that creates atmosphere as well as visibility. The emergence and popularity of remote controlled lights, connected lights, dimmers, automatic timers, and energy-saving sources have seen a crop up of light technology within home décor. The purpose of light goes beyond visibility. At its core, light serves to create an atmosphere, emotion, and warmth. Lighting architects use light to create ambiance and space as part of their design, and many people use lighting to influence their feelings of ease or excitement. Lighting is used around the world today, from major cities to small villages. It has traditionally played an important role in the lives of people who depend on it for guidance, illumination, and atmosphere. With the current advancements in lighting technologies, its clear that the power of light will stay with us for generations to come.
