A laboratory based electroencephalography (EEG) study was conducted to investigate the probable temporal processes in the brain for detection of object designed under metal halide (MH) and high-pressure sodium (HPS) light sources. Participants in this study were instructed to respond to either match or mismatch condition in a match/mismatch-to-sample task. The image stimulus contained object under metal halide and high-pressure sodium lamp. The scalp topographic plots of the event related activity showed that object detection was faster under MH than HPS. Significant differences in scalp activity were also identified. This approach can be considered as future metric for assessment of lighting installation for visual acceptance designing.
