Incandescent light bulbs became the most common source of lighting for modern chandeliers in the 20th century, and a variety of electrical lights such as fluorescent light, halogen. LED lamp are also started to be used in the later part of the 20th century. Many antique chandeliers not designed for electrical wiring have also been adapted for electricity. Modern chandeliers produced in older styles and antique chandeliers wired for electricity usually use imitation candles, where incandescent or LED light bulbs are shaped like candle flames. These light bulbs may be dimmable to adjust the brightness. Some may use bulbs containing a shimmering gas discharge that mimics candle flame.
