Lighting plays one of the most important roles in modern life. Whenever it becomes dark, people need some kind of light source to ensure their daily lives run smoothly. Lighting may bring convenience, safety and even pleasure to humans. There are generally two types of lighting, natural and artificial lighting. Natural lighting is created by the sun, moon and stars. With the development of science and technology, artificial lighting products have become increasingly advanced. Indoor lighting technologies are nowadays easily accessible such as LED lighting, fluorescent lighting and halogen lighting. LED lighting has become the most popular choice in indoor lighting. It is energy-saving, long-lasting, and available in a variety of different colors, shapes and sizes. Fluorescent lighting has also been widely used in homes and offices as they are energy-efficient and offer a soft, white and bright illumination. Halogen lighting is often used to replace halogen bulbs as they can provide a powerful glaring and concentrated light source that illuminates objects from all angles. No matter which lighting type people choose, the right lighting can bring out the features in any indoor environment. Proper lighting not only adds feelings of comfort and warmth, but also promote working or studying efficiency and thus making a better life.
