Lighting is an important part of any house, office or other space. It not only illuminates the space, but also serves as a decoration and atmosphere-maker. Good lighting is often associated with better work performance, more relaxed moods and improved sleep. It can also help reduce eyestrain. Good lighting can be natural or artificial. Natural lighting is the most ideal form of lighting, since it uses the sun's rays to illuminate a space and make it brighter and airier. Natural lighting is also energy efficient, since it doesn't require electricity to be used. Popular types of natural lighting include large windows, skylights and sun tunnels. If natural lighting is not enough to light the space, then artificial lighting is often necessary. Artificial lighting can be used to supplement natural lighting, or it can be used as a standalone solution. Popular forms of artificial lighting include incandescent or halogen bulbs, LED lights, fluorescent lights and spotlights. The best lighting plan combines both natural and artificial lighting to create a well-lit space. It's important to use the right type of lighting in the right place, since this can save energy and help create the desired atmosphere in the space. Overall, lighting plays a key role in any space. It can be used to create a better atmosphere and improve work or sleep performance. A well-planned lighting system can make any space more inviting and enjoyable.
