An important property of light fixtures is the luminous efficacy or wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the surroundings.
Pendant lights are fixed to the ceiling with a pole or chain that allows the bulb and shade to hang down. The chain or pole will tend to be silver in color but can also be bronze or even black. This type of contemporary lighting can be found in a single light fixture or one that includes many bulbs.
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.
