The comfort of any indoor space depends on the lighting. Optimal lighting produces not just a good ambience, but also comfort and calmness, whereas too bright or too dim lighting deteriorates the quality of the space and may create unease, stress, or loss of productivity. The basic considerations for good interior lighting are optimal lighting level, contrast, and light distribution. Optimal lighting levels increases the speed and accuracy in detecting or locating objects. The optimal value is relative, with any light high enough for sufficient visual performance, considered as optimal. Low luminance contrast results in a dull and flat visual scene, and high contrasts poses difficulty for the eye to adapt when changing from one visual target to the other. Well-balanced contrasts, on the other hand, offer gives satisfaction and comfort. As a rule of thumb, the optimal luminance contrast ratio, or the ratio between highest and lowest luminance in the field of view, is larger than 3 and not smaller than 1/3. Related to luminance is the glare, or the sensation produced by the brightness levels of the light. High glare results in reduced visual performance, and cause discomfort, eye strain and headache. The degree of glare depends on the quality and type of the light. The way light is distributed in indoor places determines the pattern of luminance. For instance, using ambient or diffuse lighting spreads the light evenly, and using directional or accent lighting allows concentrating light on particular areas. The use of such lights depends on the situation and the functionality of the space. For instance, ambient lighting, with ceiling bulbs or tubes is best suited for the kitchen or bathroom, to perform daily and routine tasks, in a comfortable manner. In porticos or corridors, accent lighting, which accentuates specific elements of the decor, such as architectural detail or artwork, may be more appropriate. Good lighting however goes beyond such considerations of efficiency and functionality, and serves to complement the overriding theme of the space. The lighting determines, to a large extent whether a space is cool, lively, romantic, businesslike, warm, cosy, or anything else. For this reason, there are no absolute values for the preferred lighting attributes, and the optimal values depend on the context and the purpose for which the space finds use. The tradeoff between functionality and elegance poses a perennial challenge. Which light best suits specific rooms? To what extent can the tradeoff between functionality and elegance be justified? How does the element of cost factor in the equation? The answers are open-ended.
