Chandeliers are also known as suspension or chain-hung fixtures. Like ceiling fixtures, chandeliers are also hung from the ceiling. However, they require more space in addition to adding more pizzazz compared to regular ceiling fixtures. They provide general lighting and have at least two arms with down-lights or up-lights. They are most often used with formal dining rooms or dining tables.
Cabinet Lighting: These lighting fixtures are mounted underneath a cabinet or shelf and provide illumination for a particular task. They are most often placed in kitchen cabinets to act as pinpointed spotlights for cooking, but they can also provide accent brightness for home office or living room shelves.
Major reductions in the cost of lighting occurred with the discovery of whale oil and kerosene. The potential of electric light as a new building material was recognized in the 1920s and became a useful design tool by the mid-century. Skillful lighting allowed for theatricality, narrative, and a new emphasis on structure and space. Gas lighting was economical enough to power street lights in major cities starting in the early 1800s, and was also used in some commercial buildings and in the homes of wealthy people. The gas mantle boosted the luminosity of utility lighting and of kerosene lanterns.
Other buildings, like casinos and theatres, are primarily concerned with enhancing the appearance and emotional impact of architecture through lighting systems. Therefore, it is important that the sciences of light production and luminaire photometrics are balanced with the artistic application of light as a medium in our built environment. These electrical lighting systems should also consider the impacts of, and ideally be integrated with, daylighting systems. Factors involved in lighting design are essentially the same as those discussed above in energy conservation analysis.
