Background and aims: Human beings are exposed to various light effects. Light can be effective in Cognition, human behavior, visual comfort, health and well-being. The purpose of this study was to Comparative Survey on the effect of fluorescent lamps and LED color temperature on staffs Cognitive Performance Indicators at the office.
Methods: In this interventional study, 8 subjects including 2 men and 6 women with mean and standard deviation of 41.75 ± 5.99 years were studied. Exposure to three levels of brightness includes a fluorescent lamp with a color temperature of 6,500 Kelvin and a LED3000 K and 6,000 K at a time of one week's adaptation for each of the brightness levels, the reaction time was measured using the simple reaction timer software, Attention was measured using the SELECTIVE & DIVIDED ATTENTION TEST software and working memory by The N-BACK (WORKING MEMORY TEST) software was measured.
Results: The results of the Attention and working memory tests showed that the average of each under the conditions of the LED lamp with a color temperature of 6000K increased compared to two other lighting conditions. And this difference was significant (p<0.05).
Conclusion: The results of this study showed that increasing the color of light and the intensity of light increase the attention and working memory and reducing the reaction time leads to improvement of cognitive Performance of employees. As a result, by choosing the correct type of lighting at the workplace, not only will the person's health be safe, but also the level of staff Efficiency will rise.
