Lighting plays an important role in many aspects of our lives. From artificial lighting to natural lighting, light affects how we feel, how productive we are, and how safe our environment is. Artificial lighting is used to increase visibility in dark areas, to supplement natural lighting, and to create moods and ambiance. Many businesses, such as restaurants, hotels, and stores, use various types of artificial lighting to create a specific atmosphere. Lights can be used for tasks such as reading or cooking, or to provide additional safety. LED lighting is becoming more popular due to its energy-saving, long-lasting and efficient feature. Natural lighting can also have a significant effect on our well-being. Direct sunlight can help give us an energy boost, and natural light can even be used to improve health. Natural lighting can be used to achieve higher productivity levels in certain workplaces; for example, some offices have been designed to allow for maximum light intake from outside. Lighting is a powerful tool that can be used to create a more enjoyable and productive environment. From artificial lighting to natural lighting, light can make a big difference in our day-to-day lives.
