Light Intensity and Hanging Height
Light Intensity: Will the chandelier provide sufficient lighting for the specific room? For a dining room or living room, you'll need more light than in a bedroom, for example. You definitely don't want to be guessing what's on your plate during dinner. Keep in mind that the intensity of the lighting should correspond to the size of the room and the activities that take place there.
Hanging Height: The chandelier should hang high enough not to obstruct movement, but also low enough to properly illuminate the space. The ideal height above a dining table is 75–90 cm from the table's surface. In a living room, the recommended clearance height (the distance from the bottom of the chandelier to the floor) is 220 cm.
