Energy-saving lamps, incandescent, fluorescent lamp which power factor the highest
Incandescent lamp is purely resistive, it is in operation, will not produce current shift phase AC, voltage and current is always conservative in phase
They will save a lot on the line with the use of components, will lead to lower power factor, usually only 0.92 or so.
Early use of inductive ballast, the inductor will cause the current phase to lag
The power factor is a measure of the efficiency of the power supply for the power supply.
