Abstract |
Volunteers conducted a quantitative analytical task under 3 different lighting regimes: fluorescent lighting powered with alternating current at normal mains frequency (100Hz), fluorescent lighting powered by a high-frequency source (4kHz) and a mixture of natural light with normal-frequency fluorescent light. Visual fatigue was least with the high-frequency illumination and worst with the normal-frequency illumination; mixed lighting gave intermediate values of the performance criteria measured. Thus, the 100-Hz flicker of normal fluorescent lights has definitely deleterious effects. These effects are best obviated by changing the power supply (revision of lighting codes may be required), but they can be counteracted to some extent by including natural light in the illumination of the workplace. |
