In this study, measurements of various domestic light-emitting diode (LED) lamps were conducted to investigate the effects of varying illuminance, correlated colour temperature (CCT), and colour rendering index (CRI) on visual perception; and to determine the users' preference of those parameters under LED lamps in Indonesian context. The assessments consisted of subjective performance and preference tests. Variation of illuminance, CCT, and CRI of has been found to yield significant effect on user performance and preference. On lighting level, variation of both illuminance and CCT yields more significant effect compared to CRI. On colour appearance, variation of CCT yields more significant effect compared to CRI. Variation of CCT also yields more significant effect on colour clarity and visual comfort. The subjects preferred higher CRI value for visual comfort, also at illuminance 350 lx and CCT 6500 K; but preferred higher illuminance and CCT for good lighting level and colour clarity.
