Lighting is an essential part of modern life. It shapes the way we interact with the world, by making our environments appear more inviting, comfortable, and safe. Indoor lighting has changed drastically over the last century. Originally, homes were lit up using candles and gas lamps. Today, electric lighting is used everywhere, and it has almost completely replaced older lighting sources. LED lights have become the most popular form of electric lighting, due to their energy efficiency and bright, crisp light. LED lights can be found in virtually every room and hallway of a house, and are even used to light up gardens and other outdoor spaces. Outdoor lighting serves multiple purposes, including providing safety and visibility for pedestrians and drivers alike. Common examples of outdoor lighting include street lamps, security lights, and decorative lights. Street lamps, which are usually powered by electricity, are typically used to light up roads and pathways. Security lights are bright, powerful lights used to deter burglars and other criminals. Decorative lights are lights that can be used to make a space appear more picturesque or unique. Lighting is essential in creating a comfortable and inviting atmosphere. With the advancement of technology, lighting has continued to evolve, allowing us to enjoy brighter, more efficient lighting in our homes and outdoors.
