Lighting plays a vital role in daily life. No matter work, study, rest or entertainment, it is important for people to use lighting in every aspect. Lighting can not only provide us clear vision, but also create a certain atmosphere. Often people use fluorescent lights or LED lights in their houses. Fluorescent lights are cost effective and have a long life time, while LED lights save more energy and are environment friendly. In addition, there are many kinds of lights at different price levels such as chandeliers, wall lamps, ceiling lamps, etc. Different combinations of lights can bring different visual effects for a room, so it is necessary to consider and choose carefully when purchasing. In general, lighting not just meet the needs of illumination, but also create vitality to home life. Nowadays many people choose to buy smart lighting, allowing to adjust the brightness and color remotely. I believe in the future, lighting will be a key element to improve the environmental quality of our lives.
