Lighting is the purposeful use of light to achieve a practical or aesthetic effect. It can be both natural and artificial and has been used since the earliest times to brighten caves, make complex tasks feasible and to create artistic effects. Natural lighting includes sunlight, which can be seen in many buildings during the day, as they often have large windows that allow natural light to enter and brighten the room. This light can also be managed through the use of external awnings, shades, window blinds or curtains. Artificial lighting is used to extend the range of lighting beyond the natural daylight available and for tasks that require more light. This can be accomplished through a variety of fixtures including: wall sconces, track lighting, recessed lighting, pendants, chandeliers, table lamps, and floor lamps. Each fixture has a particular use and meaning, making artificial lighting extremely useful for creating atmosphere, visual tasks, and setting the mood. Lighting also has many functional uses, from providing visibility in dark areas to alerting people to potential hazards. As energy costs continue to rise, it is important to recognize the importance of using energy efficient lighting, including LED and Compact Fluorescent bulbs. In short, Lighting is essential for everyday life. It provides light to see our way, it helps make tasks easier and is essential for creating atmosphere, performing visual tasks, and setting the mood. By using energy efficient lighting, we can reduce costs both financially and for the environment. A well thought out lighting plan benefits everyone.
