The orientation of a room (north, south, east, west), window size, and seasonal light changes all affect how much and what kind of artificial light is needed to maintain consistent ambiance and functionality throughout the day.
3. A client's dining room has an 8-foot ceiling. At what height should a chandelier typically be hung above the dining table surface?
