This research examines the reduction of exposure of museum exhibits to incident radiant power without reducing the level of visual satisfaction for museum visitors. Many types of museum exhibits are susceptible to damage caused by exposure to light. Current recommendations for museum lighting include avoidance of non-visible radiant power (UV and IR), limitation of light level, and restriction of exposure duration. However, these recommendations do not distinguish between the potential of incident radiant power in the visible spectrum to stimulate the sense of brightness (illuminance) and its potential to cause damage (irradiance).
This research was made possible through Grant MT-2210-7-NC-14 from the National Center for Preservation Technology and Training (NCPTT).
