Labeling of household appliances in terms of energy consumption has been considered as one of the efforts to increase people awareness on energy saving. Recently, light emitting diode (LED) lamps have been widely utilized for lighting, replacing the conventional compact-fluorescent (CFL) and incandescent lamps, due to its low-energy consumption. Because LED lamps work with switching procedures, it may produce distortion to the electrical power system. Furthermore, so far there are no rule or technical guidelines in Indonesia on labeling and grouping of the LED lamps. This study firstly aimed at classifying the LED lamps through measuring the level of efficacy and power quality parameters, including power factor (PF) and total harmonic distortion of current (THD-I) generated by LED lamps and grouped it based on efficacy and power quality. A numerous test of 2-13 W LED lamps available in the market was performed, following the procedure of Indonesian national standard (SNI) that adopted IEC 62612:2016. We proposed two types of label that use in energy efficiency marking. We refer the related ministerial regulation to indicate the efficacy level and propose the new procedure to label the power quality level. The results were then grouped for labeling using the number of stars 1, 2, 3 and 4. We found that the efficacy level of the most measured LED lamps (85%) was in the range 63-104 lm/W with PF and THD-I of 0.21-0.86 and 33%-189%, respectively.
