Architectural lighting design focuses on three fundamental aspects of the illumination of buildings or spaces. The first is the aesthetic appeal of a building, an aspect particularly important in the illumination of retail environments. Secondly, the ergonomic aspect: the measure of how much of a function the lighting plays. Thirdly is the energy efficiency issue to ensure that light is not wasted by over-illumination, either by illuminating vacant spaces unnecessarily or by providing more light than needed for the aesthetics or the task.
In the mid-19th century, as gas lighting caught on, branched ceiling fixtures called gasoliers (a portmanteau of gas and chandelier) were produced, and many candle chandeliers were converted. 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.
Chandeliers: Chandeliers have multiple lightbulbs combined in one unit to create a larger, more dramatic statement piece. Unlike pendants, they produce a stronger glow and therefore can often stand alone. Chandeliers are traditionally more elegant and more expensive than other indoor lighting fixtures, and therefore are used less frequently — you may see one in an entryway or a formal dining room.
