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.
Track Lighting: Like a chandelier, this interior lighting source includes several lightbulbs in one fixture, but instead of being grouped together, the bulbs are strung along a horizontal track. Tracks are a more casual way to get a lot of illumination in one space, and therefore they look good in less formal settings, such as a hallway, an office or a kitchen. Most of them can be positioned to highlight specific areas, which makes them great for showcasing artwork.
Chandeliers: Chandeliers have multiple lightbulbs combined in one unit to create a larger, more dramatic statement piece. Unlike pendants, they produce a stronger glow and therefore can often stand alone. Chandeliers are traditionally more elegant and more expensive than other indoor lighting fixtures, and therefore are used less frequently — you may see one in an entryway or a formal dining room.
