Light requirement is a feature of a user which is hard to predict. For example, if a sanitary standard says that the minimum light intensity recommended for a stay in a room is 200lx, there are always people who will require 500lx or more. What is more, the older a user is, the higher his light requirement is. Various demands on the intensity of light can me met in various ways. A chandelier with a higher number of bulbs whose light intensity we want to decrease can serve as an example. Such a decrease in the light intensity can be reached by: installing a double switch (the chandelier will be only partially lit), installing a dimmer (the light intensity of all lit bulbs will be gradually regulated), exchanging current bulbs for ones with a lower power.
The earliest chandeliers were very basic, almost primitive devices that involved two pieces of wood connected together to form a cross. A spike was inserted at each end to hold the candles and a rope or chain was connected to the crosspiece and then suspended from the ceiling. As a former antique dealer, Ive found that nearly all of the earliest chandeliers were destroyed and very few authentic examples remain in existence today. The chandelier found its resurgence in the eighteenth and nineteenth centuries and was found in the great palaces of Europe and America.
Between the 11th and the 15th century, the Flemish town of Dimant became famous for its chandelier brass works, and in the 16th century the Dutch brass ball chandelier became popular. Over the next couple of centuries, chandeliers became popular, particularly for the very wealthy and royals. The chandeliers changed in many ways, shapes and sizes as technology and fashion modernised and transformed. In the 17th century, the first chandeliers featuring rock crystals were manufactured. These chandeliers were the first of the more extravagant and decorative chandeliers.
