In working environments all over the world, fluorescent tubes are by far the dominating light source. Still, there have been very few studies on the impact of the non-visible flicker from fluorescent tubes. The purpose of the study was to compare the impact on subjective well-being, performance and physiological arousal of fluorescent light powered by conventional and high-frequency ballasts. Thirty-seven healthy males and females were subjected to either condition in a laboratory office on two separate occasions with 1 week in between. Although the methodology was quite extensive, only a few general effects were observed. However, when the light was powered by the conventional ballasts, individuals with high critical flicker fusion frequency (CFF) responded with a pronounced attenuation of EEG alpha 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 ballasts of good quality.
在世界各地的工作环境中，荧光灯管是目前占主导地位的光源。然而，关于荧光灯管不可见闪烁影响的研究却非常少。本研究的目的是比较传统镇流器和高频镇流器驱动的荧光灯对主观幸福感、工作表现和生理唤醒的影响。37名健康男性和女性在实验室办公室分两次接受两种条件的测试，中间间隔1周。尽管研究方法相当广泛，但仅观察到一些一般效应。然而，当灯光由传统镇流器驱动时，具有高临界闪烁融合频率（CFF）的个体脑电图α波明显衰减，表现出速度增加但准确性下降。这些结果可以从中枢神经系统因传统镇流器引起的明显光调制而唤醒增强的角度来理解。为了减轻这种潜在的压力源，建议使用优质的电子高频镇流器为荧光灯供电。
