Abstract

100 hue test was conducted under a normal lighting with fluorescent lamps and under a spot lighting composing of three LED lamps with a deep hood to eliminate environment light. Fifteen subjects participated in the experiment. Each subject did 100 hue test with cataract experiencing goggles to simulate elderly eyes. All the subjects gave better score with spot lighting than fluorescent lamp lighting. Mean error score was 197 with the spot lighting, whilst it was 215 with fluorescent lighting to show that spot lighting can present a better lighting environment to elderlies than normal lighting that radiates light.
