The Impact of LED Correlated Color Temperature on Visual Performance Under Mesopic Conditions

The Impact of LED Correlated Color Temperature on Visual Performance Under Mesopic Conditions

The aim of this study was to investigate the impact of correlated color temperature (CCT) of LED light source on human vision performance in mesopic region. First, six CCTs (3500, 4000, 4500, 5000, 5700, and 6500 K) were assessed using mesopic photometry model MES-2. The calculation results indicate...
