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.
Dining Table: The pendant should be suspended about 30 to 36 inches above the table. This will allow for ample illumination while reducing glare at the same time. Bar or Raised Counter:: The bottom of your pendant light should float about 30 inches above the counter surface. For desks, bring the light in closer to the work surface by allowing your pendant lamp to float about 16 inches from the surface. However, this can change depending on the height of you and your family. Foyer: Illuminate your space without encroaching on head space by suspending your hanging lamp about seven feet from the floor.
An important property of light fixtures is the luminous efficacy or wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the surroundings.
