Vertical lighting is a fundamental element in architectural lighting for both design and normative reasons. Under identical levels of illuminance, a vertical surface produces a higher impression of brightness than a horizontal surface because walls are in our natural field of vision. Less lighting, and thus energy, is required in illuminating walls versus the floor for a similar impression of brightness; for example, illuminating walls instead of floors with 100 lux will make a room appear three to five times brighter.
