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.
The shades on a contemporary light will be made of light brown, beige or classic white. The shades that cover the bulb can be square or cylinder in shape. Pendant lighting would be best used over the top of counters or bars for a dramatic affect on the area or in dining areas.
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.
Fireflies have been used as lighting sources. Candles and glass and pottery lamps were also invented. Chandeliers were an early form of light fixture. The earliest candle chandeliers were used by the wealthy in medieval times, this type of chandelier could be moved to different rooms. From the 15th century, more complex forms of chandeliers, based on ring or crown designs, became popular decorative features in palaces and homes of nobility, clergy and merchants. Its high cost made the chandelier a symbol of luxury and status.
