Lights at Work (03-03-14)

Dangol and colleagues have comprehensively assessed the color and intensity of lights that workers prefer.  Study participants working on office-related tasks “preferred 4000K to 6500 K at a light level of 500 lux and the light level of 500 lux over 300 lux.”  At both 4000K and 6500K, LED lighting was generally preferred to fluorescent lighting of the same color and intensity (fluorescent light was preferred at 6500K and 300 lux).
