Pendant Lights: A pendant light is a smaller fixture suspended from the ceiling by a cord, chain or metal rod. Pendant lights traditionally include only one lightbulb, so they don’t cover as much ground; several are often used to cover more space. There are many styles of these lights, including drum pendants and globe pendants, making it easy to find one that will fit your decor. They work well when you’re trying to showcase a smaller, specific area, such as a kitchen island or a dining room table.
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.
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.
Extensive luminaire photometric designing calls for consideration of the amount of functional light present, the energy expended, as well as the aesthetic impact supplied by the lighting system. Some buildings, like surgical centers and sports facilities, are primarily concerned with providing the appropriate amount of light for the associated task. Some buildings, like warehouses and office buildings, are primarily concerned with saving money through the energy efficiency of the lighting system.
