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.
Architectural lighting design focuses on three fundamental aspects of the illumination of buildings or spaces. The first is the aesthetic appeal of a building, an aspect particularly important in the illumination of retail environments. Secondly, the ergonomic aspect: the measure of how much of a function the lighting plays. Thirdly is the energy efficiency issue to ensure that light is not wasted by over-illumination, either by illuminating vacant spaces unnecessarily or by providing more light than needed for the aesthetics or the task.
Bathrooms can also make use of the contemporary ceiling lights with ease. These lights are usually flush mounted to the ceiling and may or may not include a fan in their design. They can be found with the sleek stainless steel fixture that holds onto a clear or white shade. There are also ceiling lights sold that are semi flush in design.
As these light sources change so does the practice of lighting Design. By the early 18th century, ornate cast ormolu forms with long, curved arms and many candles were in the homes of many in the growing merchant class. Neoclassical motifs became an increasingly common element, mostly in cast metals but also in carved and gilded wood. Chandeliers made in this style also drew heavily on the aesthetic of ancient Greece and Rome, incorporating clean lines, classical proportions and mythological creatures. Developments in glassmaking later allowed cheaper production of lead crystal, the light scattering properties of which quickly made it a popular addition to the form, leading to the crystal chandelier. During the 18th century glass chandeliers were produced by Bohemiens and Venetian glassmakers who were both masters in the art of making chandeliers.
