Lighting is a vital part of our everyday lives. It has many uses, from providing light for us to seeing in the dark to providing atmosphere in a room. It is no doubt that lighting plays an important role in our lives. First, lighting allows us to see in the dark. As night-time approaches, it is necessary to turn on lights inside buildings and outdoors. For centuries this was provided by the natural light of the moon and stars, but now it is usually provided by electric lighting. Without lighting, many of the activities that we take for granted, such as traveling after sunset and reading late at night, would be impossible. Second, lighting provides atmosphere in a room. Different types of lighting can transform the look and feel of a room. For example, bright lights can create an energizing and invigorating atmosphere while dim lights can create a cozy and intimate atmosphere. The use of lighting can also influence the mood of a person. It can be used to create feelings of joy, warmth, relaxation, or even fear. Finally, lighting can be used to improve safety. When used correctly, lighting can help people see obstacles, identify potential threats, and alert others of their presence. This is especially useful when walking outdoors at night or in a parking lot. In conclusion, lighting is one of the most important tools we have to make our lives easier and more comfortable. Whether its providing light to see in the dark, creating atmosphere in a room, or helping us feel safe, lighting plays an important role in our lives.
