This study examined North American and South Korean preferences for different lighting conditions in a hotel guestroom. A sample of 87 North Americans and 88 Koreans (N = 175) rated their preference for different intensities and color temperatures of light within a digitally generated hotel guestroom design. A mixed between-within analysis of variance (Kuehl, 1999) evaluated three dependent variables (preference, arousal, and pleasure) against three independent variables (two culture groups × two light colors × two light intensities). Findings indicated that North American subjects preferred the hotel guestroom with low intensity and warm color lighting the most, whereas the Korean group preferred high intensity and warm color lighting the most. North American participants also perceived dim lighting as more arousing than bright lighting, whereas Korean participants perceived bright lighting as more arousing than dim lighting. Overall, the findings suggest that design criteria for hotel guestroom lighting should be revised to account for distinct cultural differences.
