Lighting has been an essential part of our lives ever since the invention of the light bulb in 1879. In the past, lighting was used just to provide illumination in our homes and workplaces. But today, lighting has become much more than a source of illumination—its become an important part of design, style, ambiance, emotion, and even safety. Good lighting can make a room look more inviting and comfortable. It can create a special atmosphere and add a sense of warmth. Lighting can also be used to create a dramatic effect—changing the mood of an entire area. Lighting can also reduce the risk of accidents and injuries at home and work. Specialized lighting can be used to highlight areas of potential danger, such as stairs and doorways. Proper lighting can also improve visibility in low-light areas, helping to prevent trips and falls. In addition to illuminating our surroundings, lighting can also be used to enhance the safety of our home and workplace. Motion detectors and timers can ensure that lighting is only used when necessary, saving energy and money. Lighting has come a long way since the invention of the light bulb. Nowadays, it can be used in many creative ways to improve the design, safety, and atmosphere of both commercial and residential buildings.
