Before purchasing any chandelier, you should know several things. One of the most important is the height of the fixture, from the tip of the lowest point to the mount. This will determine how much space you need below the chandelier for clearance. You should also consider whether the chandelier is adjustable � some are, and others are not. Adjustable height fixtures allow you to lengthen or shorten the tether/chain that secures the chandelier to the ceiling mount.
The number of lights in the chandelier is also important. Choose a chandelier that will provide you with enough light output for your installation area. For instance, you would need fewer lights to illuminate a foyer than you would in a large dining room. Of course, the bulb requirements for the chandelier are also important, as this will determine maximum light emission from individual bulb, as well as power consumption.
