Method and apparatus for reducing electrical power consumption The invention relates to a method and apparatus for reducing electrical power consumption of a plurality of electrical loads (25), wherein the method comprises a plurality of switches (20) configured to operate in an on state and an off state, the on state electrically connecting said electrical loads (25) to a power supply (26) and the off state electrically disconnecting said electrical loads (25) to the power supply (26), wherein each said switch (20) is electrically connected to at least one said electrical load (25), a processor (15) operably connected, and configured to provide respective control signals (29, 30), to each said switch (20), and wherein each said switch (20) alternatively operates in the on state for a respective first time period and in the off state for a respective second time period responsive to the respective control signals (29, 30), the respective first time period being less than the respective second time period, and wherein at least two said switches (20) do not operate in the on state simultaneously.
