"Traditionally in England, candles were used in great halls, monasteries and churches of medieval times. In addition, candles were used to light cottages and shops. King Alfred of England stuck torches in walls to supply lighting. The simplest (and smelliest) candles known as rush light were made by dipping rushes in leftover kitchen fat. For many centuries, candles were considered expensive items in Europe. Town-made candles from the wax-chandler were available for those who could afford them. These candles were made of wax or animal fat and were placed in silver, wooden or pewter candlesticks."

Therefore, until the 19th century tallow candles and rushlights were the principal form of light for the poor. The slaughter of one bullock provided enough tallow for three years’ worth of candles and a well organised household could produce 300 or so at a candle making session. The Newsfinder website (click on the link above) discusses how lighting remained essentially unchanged for hundreds of years until the early 19th century. Then, "the growth of the whaling industry in the late 18th century brought the first major change in candlemaking since the Middle Ages, when spermaceti -- a wax obtained by crystallizing sperm whale oil -- became available in quantity. Like beeswax, the spermaceti wax did not elicit a repugnant odor when burned, and produced a significantly brighter light. It also was harder than either tallow or beeswax, so it wouldn't soften or bend in the summer heat. Historians note that the first "standard candles" were made from spermaceti wax."

Regency interiors were lit in several ways: spacious windows, well placed reflectors and mirrors, fireplaces, oil lamps, rush lights, and candles. Since candles were expensive, the lower classes rose with the light and worked until dark.In Light Fittings in Georgian and Early Victorian Interiors, Jonathan Taylor writes,
"Candles were used sparingly. Even in the homes of the wealthy, when the family was not entertaining guest, only the minimum number of candles were used in a room at any one time, and these were positioned close to where the light was most needed. A single candle was carried to light the way from one room to another. Everyday lighting was therefore moveable, and not part of the architectural design of the interior."
In The Transformation of Lanhydrock House, Cornwall, 1758–1829: paper presented to the CHN Conference 2002: The Country House, the authors describe the architectural parts of a house's lighting:
"The main lighting in the eighteenth century house was by ‘2 glass lanterns’ one in the Prayer Room Passage and the other on the Staircase. The Dining Room was well illuminated by a ‘pier glass with chandelier’, ‘2 girandola in white carved frames’ and candle branches over the chimney. By c.1829 Wedgwood candlesticks and glass candelabra were replacing the more traditional candle branches and Corinthian pillared candlesticks. The emphasis towards quality lighting was displayed through the use of Spermaceti candles that were running low in stock by 1802. 26 There was no evidence by 1829 of oil lighting in the house. This reflects the often slow adherence to some aspects of contemporary technology."
After the turn of the century, there was an explosion in candlemaking technology, as the Newsfinder website describes.
"In 1709 in Britain, candles were taxed and people forbidden from making their own. This punitive tax was eventually repealled in 1831, resulting in a renaissance of decorative candles.
M. Cambaceres another Frenchman devised the plaited wick in 1825. This he steeped in mineral salts to make it curve on burning, thereby obviating the need to trim wicks.
In 1834 Joseph Morgan created a candle making machine which could produce up to 1500 candles an hour. In 1850, parrafin wax appeared, shortly followed in 1857 with the combination of stearin & the plaited wick resulting in a bright affordable candle.
The nineteenth century brought the development of patented candlemaking machines, making candles available for the poorest homes. In an attempt to protect the industry, England passed a law forbidding the making of candles at home without purchase of a special licence. At this time, a chemist named Michel Eugene Chevreul made an important discovery. He realized that tallow was not one substance but a composition of two fatty acids, stearic acid and oleic acid, combined with glycerine to form a neutral non-flammable material."
By removing the glycerine from the tallow mixture, Chevreul invented a new substance called “stearine.” Stearine was harder than tallow and burned brighter and longer. It is this substance known today as stearin or stearic acid that led to the improvement of candle quality. Stearin also made improvements in the manufacture of wicks possible. It put an end to the constant round of snuffing and trimming wicks once they were lit. Instead of being made of simply twisted strands of cotton, wicks were now plaited tightly; the burned portion curled over and was completely consumed, rather than falling messily into the melting wax.
More improvements such as the addition of lime, palmatine, and paraffin developed in commercial candle manufacture. Paraffin wax was extracted from crude oil . It equalled beeswax and spermaceti candles for brightness and hardness and were cheaper. Paraffin wax is still widely used today in commercial candlemaking."
