Lighting refers to the use of artificial light in our life, such as indoors in the office or at home, outdoor in the park, or even on the street. Lighting is an essential part of any physical environment that is lived in. Studies have found that the quality of lighting has an effect on mental and physical health, productivity, safety and security. Good lighting designs can facilitate improved moods, alertness and focus. In modern times, lighting has become an important aspect of interior design, allowing people to show their personality to others. By providing well-designed lighting as part of the living space, people can create a home that is both comfortable and pleasant to be in. Outdoor lighting also plays a vital role in providing security, safety and visibility. Effective outdoor lighting can prevent burglaries, reduce accidents and increase visibility. It can also set the mood and make the outdoors more enjoyable and safe while holding more true to its aesthetic design. Lighting can also be used to conserve energy. Incandescent lights and fluorescent lights are the two main types of artificial lighting used, and their use can be chosen to maximize energy efficiency and reduce power bills. The use of timers, motion sensors, and other efficient lighting options make it easy to keep power bills to a minimum. Lighting has become an important part of our lives as it enhances the space that we live in and helps us with our everyday activities. Whether for indoors or outdoors, lighting can improve the safety, security and comfort of the space we live in. It is essential to have the right lighting choices to maximize benefits and conserve energy.
