Lighting is an essential part of modern life. It not only illuminates our way in the dark, but also brings us beauty and comfort. The most common form of lighting is electric lighting. We use lighting fixtures in virtually every space including home, office, street, warehouse, and hospital. Through a variety of electrically powered lamps, lighting fixtures, and electrical power supplies, we can illuminate our space in the desired color and brightness. Despite its ubiquity, electric lighting is not the only option in lighting. We also have natural light. It is the oldest form of lighting and comes from the sun. Although it is not a reliable source of lighting because light intensity varies and sun exposure is weather dependent, it is free and non-polluting. Lighting technology has advanced so much that we now have access to a plethora of lighting options. Smart, automated, and energy-efficient lighting solutions are becoming more available. LED lights, for example, are three to five times more energy-efficient than traditional lights and last longer. Solar-powered lamps are also becoming more popular and are an excellent choice for outdoor lighting. No matter what kind of lighting we choose, it is important to remember that it plays an essential role in our daily lives. It not only helps us stay safe and secure, but also brings beauty, comfort, and atmosphere to our lives.
