Other buildings, like casinos and theatres, are primarily concerned with enhancing the appearance and emotional impact of architecture through lighting systems. Therefore, it is important that the sciences of light production and luminaire photometrics are balanced with the artistic application of light as a medium in our built environment. These electrical lighting systems should also consider the impacts of, and ideally be integrated with, daylighting systems. Factors involved in lighting design are essentially the same as those discussed above in energy conservation analysis.
Typically, they project down from the ceiling and are usually the biggest lighting piece found in the kitchen. These fixtures can also be hung over a breakfast nook or a kitchen table. There are two types of ceiling fixture; flush-mount ceiling fixture with the glass or diffuser touching the ceiling and semi-flush ceiling fixtures where the bowl projecting from the ceiling such that it hangs a couple of inches away, with indirect light reflecting from the ceiling (think of it like an upside down umbrella).
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.
