Lighting a space is an important element in determining the beauty and comfort of the home. Good lighting can make the interiors warm and friendly, lively or restful. Good lighting increases the efficiency in work performance, minimizes eye strain, and provides safety by cutting down the accidents. Bad lighting results in dull and dreamy atmosphere. Glare in interiors can make the users restless; uncomfortable which in turn is harmful for the health. Light as an element of art and design is used for visual comfort and to achieve desirable emotional responses. Visual comforts are those, which enable us to see easily, accurately and in comfort. Emotional responses are influenced by the manner in which light has been used to communicate ideas about color, texture, shape, form and line. Without light, there would be no visible form, color or texture nor any visible enclosure of interior space.
Light has a definite emotional effect. Light is stimulating, darkness is depressing. A sunny day makes us feel good, cheerful and active. On the other hand, a cloudy day makes us feel dull.
