By the 1890s, with the appearance of electric light, some chandeliers used both gas and electricity. As distribution of electricity widened, and supplies became dependable, electric-only chandeliers became standard. Another portmanteau word, electrolier, was formed for these, but nowadays they are most commonly called chandeliers. Some are fitted with bulbs shaped to imitate candle flames, for example those shown below in Epsom and Chatsworth, or with bulbs containing a shimmering gas discharge. The world's largest English Glass chandelier,(Hancock Rixon & Dunt and probably F. & C. Osler) is located in the Dolmabahçe Palace in Istanbul. It has 750 lamps and weighs 4.5 tons. Dolmabahçe has the largest collection of British and Baccarat crystal chandeliers in the world, and one of the great staircases has balusters of Baccarat crystal. More complex and elaborate chandeliers continued to be developed throughout the 18th and 19th centuries, but the widespread introduction of gas and electricity had devalued the chandelier's appeal as a status symbol.
