Gives methods for exposing specimens to laboratory light sources in order to assess changes produced by such exposure using xenon arc lamp, enclosed carbon arc lamp, and open-flame carbon arc lamp plus means of determining radiation dosage. The xenon arc, when correctly filtered and maintained, yields a spectrum most closely approximating to that of daylight but carbon arc sources are considerably different from daylight and their use is decreasing. Includes correlation of the effects of exposure to artificial light sources and natural daylight, use of blue dyed wool standards to measure light dosage, spectral distribution of simulated solar radiation and information concerning exposure to the light from fluorescent tube lamps.
