There is currently a significant challenge in the lighting industry to reduce electrical energy use while also delivering high quality illumination. It is well known that improved energy efficiency can be achieved by altering the spectral power distribution of electric light sources, but this often leads to an unacceptable reduction in the perceived lighting quality. The spectral power distribution that offers the optimal compromise between energy use and human well-being is not known, since the human perception data is missing, and this data is missing largely because there does not exist a light source that makes it possible to present project participants with different spectral power distributions.

目前，照明行业面临着一个重大挑战，即如何在提供高质量照明的同时减少电能消耗。众所周知，通过改变电光源的光谱功率分布可以提高能效，但这往往会导致感知的照明质量降低到不可接受的程度。在能源使用和人类福祉之间提供最佳折衷的光谱功率分布是未知的，因为人类感知数据缺失，并且该数据缺失的主要原因是不存在能够向项目参与者呈现不同光谱功率分布的光源。
