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.
Bathroom: Cast a flattering light in your bathroom vanity area by suspending an eye-catching hanging lamp or cluster of pendants near eye level and about 18 inches from the center of your sink. This unconventional lighting style will eliminate those pesky shadows under your chin, cheeks and eyes. Ceilings Higher Than Eight Feet: If you have ceilings taller than eight feet, be sure to add on three inches for each additional foot of ceiling height.
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.
Pendant Lights: A pendant light is a smaller fixture suspended from the ceiling by a cord, chain or metal rod. Pendant lights traditionally include only one lightbulb, so they don’t cover as much ground; several are often used to cover more space. There are many styles of these lights, including drum pendants and globe pendants, making it easy to find one that will fit your decor. They work well when you’re trying to showcase a smaller, specific area, such as a kitchen island or a dining room table.
