When hanging a light over a table or a kitchen island 28 to 34 inches is the recommended distance from the bottom of the light to the surface of the table or island. However the size of the light makes a difference. In general a smaller light can be moved lower and a larger light can be moved higher.
Crystal remains a popular choice for lighting fixtures and is used across the style spectrum. In this contemporary bathroom the crystal chandelier has a modern presentation drawing attention to the underlit wave ceiling.
Another important ceiling-based light source is the pendant or chandelier. The line between these two can be blurry as a chandelier is essentially just a large (and often more decorative) pendant light. Chandeliers also are more likely to have multiple bulbs (which help create more layers) but what is or is not a pendant is still a gray area especially with more modern fixtures like the one here.
