Extensive luminaire photometric designing calls for consideration of the amount of functional light present, the energy expended, as well as the aesthetic impact supplied by the lighting system. Some buildings, like surgical centers and sports facilities, are primarily concerned with providing the appropriate amount of light for the associated task. Some buildings, like warehouses and office buildings, are primarily concerned with saving money through the energy efficiency of the lighting system.
Chandeliers are another great form of ceiling lighting. Chandeliers are used for more general lighting. They are great for spreading light over a large area. A Chandelier is used more to set a design theme and create a focal point in a room. Common areas for use are in a entry, living room or dining room. They also have become a favorite of designers to class up a larger bathroom. The have used mini chandeliers to give that boring bathroom some style and class. Pendants are another great way to create a soft light that set a design theme in a room as well. Pendants are a great way to light a kitchen, office of dining nook. Homeowners, who are searching for the perfect illumination device for their home, have ample choices.
Major reductions in the cost of lighting occurred with the discovery of whale oil and kerosene. The potential of electric light as a new building material was recognized in the 1920s and became a useful design tool by the mid-century. Skillful lighting allowed for theatricality, narrative, and a new emphasis on structure and space. Gas lighting was economical enough to power street lights in major cities starting in the early 1800s, and was also used in some commercial buildings and in the homes of wealthy people. The gas mantle boosted the luminosity of utility lighting and of kerosene lanterns.
