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.
Typically, they project down from the ceiling and are usually the biggest lighting piece found in the kitchen. These fixtures can also be hung over a breakfast nook or a kitchen table. There are two types of ceiling fixture; flush-mount ceiling fixture with the glass or diffuser touching the ceiling and semi-flush ceiling fixtures where the bowl projecting from the ceiling such that it hangs a couple of inches away, with indirect light reflecting from the ceiling (think of it like an upside down umbrella).
This glass they worked with was so unique, as it was soda glass (famed for its extraordinary lightness) and was a complete contrast to all different types of glass produced in the world at that time. An incredible amount of skill and time was required to precisely twist and shape a chandelier. This new type of chandelier was called "ciocca" literally bouquet of flowers, for the characteristic decorations of glazed polychrome flowers. The most sumptuous of them consisted of a metal frame covered with small elements in blown glass, transparent or colored, with decorations of flowers, fruits and leaves, while simpler model had arms made with a unique piece of glass. Their shape was inspired by an original architectural concept: the space on the inside is left almost empty since decorations are spread all around the central support, distanced from it by the length of the arms. One of the common use of the huge Murano Chandeliers was the interior lighting of theatres and rooms in important palaces.
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.
