To identify differences between older and younger consumers and to understand the impact of different fluorescent lights on perceptions of skin appearance and glare, a 2 X 2 X 2 factorial design with repeated measures was used to identify the impact of color temperature (3000K, 4100K); color rendering index (75 CRI, 85 CRI); and age (20-30 years, over 65 years). Results indicate all subjects perceived their skin as healthier under the higher color temperature and perceived the 3000K/75CRI lighting condition as less glaring. There was no difference in perceptions between age groups. Designers can benefit from the insights this study when developing retail design.
