Lighting, also known as illumination, is an essential part of modern life, providing us with functional, social and aesthetic benefits. Lighting sets the atmosphere of an area, both indoors and outdoors, allowing people to feel safe, cozy and even luxurious depending on the style. Since the industrial age of the 1920s, lighting technology has advanced quickly, used widely in public and private spaces. Modern indoor lighting allows us to work on projects late into the night, while outdoor lighting creates a safe haven from criminals and can provide a sense of security for people who are walking, running or biking at night or early in the morning. Light fixtures now include a variety of different options, such as LED and fluorescent lighting, that can enhance the look and feel of a space while using minimal energy, and smart light fixtures that can be manipulated from devices such as smartphones or tablets. Smoke detectors, motion sensors and other lighting components help increase safety in buildings, public spaces and on walkways, while a variety of different lamps provide functional and decorative elements to a space. The lighting industry has grown to include a vast array of different technologies, styles, sizes, shapes and colors, allowing people to find the perfect lighting for any situation. Lighting is essential to modern society, enhancing our leisure time, increasing our safety and allowing us to do more with less energy. Lighting technology is constantly evolving, and will continue to do so to meet our needs in the future.
