ECONOMIC BENEFIT

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.
