This study is a preliminary study to verify the effect of long-term memory on light illumination. Experimental conditions of this study were 200, 400, 1000 lx. The color temperature was set to 5000 k in all three conditions. The participants consisted of four adults aged 24 years. The illumination was on the stand type engothh-8100 and the long-term memory was measured by the WFC task. The results showed that long-term memory was superior at 200 and 400 lx, which are relatively low illuminance than high illuminance of 1000 lx. In particular, long-term memory was found to be most active at 400 lx.
