Abstract The use of artificial light had positive and negative impact on humans. Improper use of artificial light can disrupt mood regulation. On the other hand, light also can be used to treat mood disorder. Some studies suggest that daylight quality in Indonesian settlements, especially in low-cost settlements did not meet the minimum required standard. Both the use of excessive light and lack of daylight exposure can cause mood problems. The advancement of lighting technology creates an opportunity to adjust artificial lighting to suit better for human needs. This paper aims to discuss the possible and effective strategies to improve occupant mood in home by studying the effect of CCT and illuminance level using desk study method. Internet search was used to search relevant articles using defined keywords. The literature found then filtered based on determined criteria for further review. Based on the literature that has been found, it is shown that CCT and illuminance level can be used to improve mood and other correlated conditions. Also, it is important to set artificial lighting according to activity and individual preference.
