Therefore, this paper reported research that comparing the illuminance level in the learning environment in UTAR and recognizing the users’ insights on the illuminance level. Lux meter and questionnaires were used for data collection. Questionnaires were administered to 312 respondents. The results show that the illuminance level in some of the tutorial rooms is too bright and left on even when the rooms are empty. From the descriptive analysis, it is found that almost all the respondents are satisfied with the illuminance level in both research venues. Based on the t-test, it is found the significance for pair 1 and pair 2 is greater than 0.05. Hence, there is no similarity between both research venues. Pair 1 is about the lighting condition preferred by the respondents, while pair 2 is about the condition in both research venues which includes the existence of glaring vision, headache, eye tiredness, and conditions that affect student performance. This paper concludes by suggesting that individual switches be provided for each of the bulbs.
