1. A power regulation apparatus for an electrical system having an AC power source and a load having a combination of resistive and reactive impedances, the apparatus comprising:

  • switching circuitry coupled to the AC power source and to the load; and

    control circuitry operable to control the switching circuitry in a power savings mode to modify a waveform applied to the load, said load waveform being characterized by substantially the same peak value of an AC power source waveform and a substantially lower RMS value than the AC power source waveform.
