Lighting plays an important role in our daily life. In cities, it is lighting that brightens up the night, enabling us to work, shop, play, and enjoy a night out with friends. We may not think much of it, but we rely on lighting to have a safe and comfortable lifestyle. Lighting also serves other practical and aesthetic purposes. Lighting up buildings helps them stand out in the night, making them a beacon of advancements and progress. Indirect lighting can create ever-changing shadows that decorate our walls, providing an interesting and dynamic living environment. Moreover, efficient lighting in hallways and stairwells helps us get to our destinations faster and safer. More importantly, lighting has improved our quality of life over the years. Recent advancements in LED and energy efficient lighting have cut down our electricity bills, while cleverly designed lights have enabled us to save energy. This doesnt just benefit our wallets, but also helps us reduce our environmental footprints. Lighting is ubiquitous in our daily life, providing us with the convenience of extended day and decoration. And it will continue to improve our lives as it evolves into newer, better technology.
