This product has built-in power factor correction circuit (PF~0.9). PF of a typical CFL

lamp is around 0.5~0.6. The power factor of an AC electric power system is defined 

as the ratio of the real power to the apparent power, and is a number between 0 and 

1. Because the cost of each power line and transformer in a distribution system 

depends on the peak current it is designed to handle, a distribution system that is 

designed to handle the higher currents caused by loads with low power factor will 

cost more than a distribution system that delivers the same useful energy to loads 

with a power factor closer to 1.
