Measured characteristics of compact fluorescent lamps (CFL's) and incandescent lamps with diode-type devices have low power factor (47 to 67%) and/or high total harmonic distortion (100% THD). There is little effect on a building's power quality if the CFL's comprise less than 10% of the buildings' load. Even if the CFL is as high as 26% of the building's load, the voltage distortion is less than 5%. Circuits and their estimated costs are presented to correct for power factor and suppress the harmonics.
