It is more apt if the ceilings of your home are not too high. These semi-flush ceiling lights are available in a number of styles, designs & sizes. These are perfect lighting arrangements for bedrooms, living rooms etc. as they bring a sophisticated look to your room. Spot lights: These are another type of ceiling if you want a specific direction of lighting. These lights can be clustered into groups of two, four, eight etc. placed inside a bracket made of plastic, wood etc. as you feel like. You can also position it in your desired direction keeping in your mind which areas you want to get lit up.
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.
With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric people used primitive lamps to illuminate surroundings. These lamps were made from naturally occurring materials such as rocks, shells, horns and stones, were filled with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. Hundreds of these lamps (hollow worked stones) have been found in the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick.
