Modern lighting sources like light emitting diode (LED) lamps and compact fluorescent Lamps (CFLs) have high efficiency and very low power consumption compared with traditional lighting sources like fluorescent and incandescent lamps. On the other hand, these modern lamps like any other nonlinear loads are considered a source of harmonic generation and a low power factor compared with incandescent lamp. In this paper, Total harmonic distortion of current (THDI) of various combinations of LED lamps and CFLs are experimentally evaluated and compared in different cases. Then, a reactor is connected, in series, to the same combinations of LED lamps and CFLs. Moreover, THDI and power factors of these combinations of lamps, before and after using the reactor, are compared to show the impact of using the reactor. The results show that CFLs and LED lamps produce very high level of harmonics; these harmonics decrease when using a mixed combination of LED lamps and CFLs and using the reactor improves the power quality of the lamps. Measurements were taken by Chauvin Arnoux C.A 8336 power quality analyzer.
