The usage of LED bulbs is steadily increasing each year. This increase causes the transition from the use of conventional light bulbs to LED bulbs. This research is done in response to the low number of research in Indonesia regarding the acceptance of LED light bulb. This specific research is conducted in order to discover the influence of physical parameters from CRI, CCT, and iluminance from LED samples towards the subjective perception of Indonesian citizens, which are colorfulness, brightness, impression, and comfort. The respondents results of the perception, preference, and performance test questionnaire used in this research is statistically processed using the Analysis of Variance (ANOVA) method. According to the statistical analysis, there are some perception evaluation results which are affected by a few physical parameters of CCT, iluminance, and CRI. From the test results, it is found that CRI influences brightness (F=7.52; p=0.00), colorfulness (F=3.02; p=0.01), and visual comfort (F=2.93; p=0.00). CCT influences brightness (F=59.87; p=0.00), colorfulness (F=32.10; p=0.00), visual comfort (F=27.09; p= 0,00), and impression (F=142.9; p=0.00). Iluminance influences colorfulness (F=5.94; p=0.00), brightness (F=63.2; p=0.00), and visual comfort (F=4.07; p=0.00). Lastly, on the performance test, the results of HSB test is influenced by CRI (F=18.71; p=0.00), CCT (F=11.04; p=0.00), and iluminance (F=11.72; p=0.00). Results of acuity test is influenced by CCT (F=3.22; p=0.04). The preferred CRI value is 88.1, and the preferred CCT value is 6500K, while the preferred iluminance value is 350lux.
