Lighting is an important factor in improving the overall environment in a room. Proper lighting can keep us stress free, provide visual comfort, and make spaces more attractive. Lighting comes in two basic categories: electric lighting and natural lighting. Electric lighting is more versatile and provides the brightness required for working and living in our everyday environment. Natural lighting is more subtle but still important in optimizing the user experience of a room. Natural lighting can also provide ecological and health benefits due to reduced energy use. When it comes to electric lighting, there are many types of lamps and bulbs available, including incandescent, fluorescent, LED, and many others. The choice of lamp will depend on the specific requirements of the room and the atmosphere desired. LED lighting is currently the most efficient of the electric lighting types and can provide the best value for money. When it comes to natural lighting, the main considerations are the type of windows and the number and size of them. Windows should be designed to maximize the amount of light coming in, but also to control the amount of heat and UV light coming in, if necessary. Lighting affects not just how a room looks, but also how it feels. So it is important to consider all aspects of lighting when designing a room. The right lighting can transform a room from dull to delightful.
