Power quality indices of Compact Fluorescent Lamps for residential use — A New Zealand study

This paper discusses the power quality indices of Compact Fluorescent Lamps (CFLs) used in residential lighting. Harmonic indices are important factors when analyzing residential power quality. Research carried out in the recent past has highlighted power quality issues relating to CFLs. The experiments performed by us confirmed the stated issues. Most brands tested had low power factor associated with high harmonic current levels. A few high power factor products with low harmonic current levels also exist and were highlighted in this research.
