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.
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.
