Our resulting scenes look like they were lit with sophisticated rigs, or in an environment that allotted far more natural light than was actually available.
The colour depends on the properties of the semiconductor, and these can be tuned to produce light that is similar to natural daylight but with virtually no ultraviolet or heat.
About 93 percent of 3, 040 large U.S. hospitals used one or more day lighting or lighting conservation features, including tinted window glass (80 percent), reflective window glass (39 percent), external overhangs or awnings (47 percent), skylights or atriums designed to provide light (57 percent), automatic controls or sensors that increase or reduce lighting in response to the level of natural light (14 percent), and occupancy sensors that reduce lighting when rooms are unoccupied (46 percent).
