| Abstract |
| This study investigated a learning environment that can enhance memory using LED lighting. Thus, it employed experimental verification to evaluate the effect of LED lighting's illuminance and correlated color temperature on long-term memory. The lighting environment was created under six conditions: two illuminance levels of 400 lx and 1,000 lx, and three correlated color temperatures of 3,000 K, 5,000 K, and 7,000 K. The participants of this study consisted of 30 cognitively healthy adults, with an average age of 21.7 years (SD = 1.73). The learning (memory) task used meaningless letters of only seven consonants, and the word fragment completion task measured memory retention after 20 minutes. The results of the study revealed that a relatively dim light of 400 lx, 5,000 K condition yielded the best long-term memory (Mean = 37.67, SD = 14.55), while the 1,000 lx, 5,000 K condition elicited the worst long-term memory (Mean = 25.67, SD = 12.78). |
