Light is one of the important factors in a room design. And adequate lighting will give the impression of good scenery and refreshing environment. Watching movie is an activity that is often done in daily life by elder people and youngster. This study examined the best light setting of elder people and youngster during the watching movie task. The total of the subjects are 24 people consisting of 12 elders and 12 youngsters are participated in this study. In this study are examined four different light settings through analyzing ECG and EEG were used to evaluate their physiological signal. Result showed that high color temperature will make people have more visual fatigue during watching movie. The illumination of 500 lx and color temperature of 3000K will make elder people have less visual fatigue. On the other hand, 150 lx of illumination and 3000K of color temperature will make young people have less visual fatigue
