A chandelier (/ˌʃændəˈlɪər/; also known as girandole, candelabra lamp, or least commonly suspended lights) is a branched ornamental light fixture designed to be mounted on ceilings or walls. Chandeliers are often ornate, and normally use incandescent light bulbs, though some modern designs also use fluorescent lamps and recently LEDs. Chandeliers evolved from candelabra and were invented during the medieval period. They originally used, as their source of light candles, which remained in use until the 18th century, when gas lights, later superseded by electric lights, were invented.
