Lighting is an essential factor in our daily life that influences our outlook and wellbeing. Proper lighting can make a tremendous difference in the feel of a room and in how we perceive work, rest, and play. From the most basic incandescent bulb to the most sophisticated illumination and lighting control system, lighting has come a long way in terms of both technology and design. Lighting technology has made it possible for us to use energy more efficiently, to create light effects that highlight certain areas of a room, and to use lighting to enhance the overall atmosphere of a space. Today, lighting is used to create atmosphere in a range of settings; from businesses, where it can set the tone and speed of work, to residential spaces, where it can promote relaxation and a sense of wellbeing. Lighting can be used to create moods, to focus attention on certain areas or objects, or to provide functional illumination. With advances in LED technology, energy-efficient lighting is now being used in all types of environments, from commercial buildings to residential homes, to help save on energy costs. Lighting has come a long way over the years, and today it plays an integral role in modern life. Whether used to create a certain atmosphere, provide illumination or simply add a touch of style, lighting can have a profound effect on our environment, our moods, and how we go about our daily lives.
