||The impact of flicker from fluorescent lighting on well-being, performance and physiological arousal
||Apr. 1998, Vol.41, No.4, p.433-447. Illus. 57 ref.
||35 individuals were subjected to fluorescent light powered by conventional and high-frequency ballasts in a laboratory office on two separate occasions with one week in between. Only a few general effects were observed. However, when the light was powered by the conventional ballasts, individuals with high critical flicker fusion frequency responded with a pronounced attenuation of EEG α waves and an increase in speed and decrease in accuracy of performance. These results may be understood in terms of heightened arousal in the central nervous system in response to the pronounced light modulation caused by the conventional ballasts. In order to alleviate this potential stress source, it is recommended that fluorescent lighting be powered by electronic high-frequency ballast of good quality. Topics: arousal; artificial lighting; biological effects; cognitive performance; electroencephalography; flicker; fluorescent tubes; luminance; neuropsychic stress; subjective assessment; work capacity.
