1. A lighting system with wireless power transfer comprising:

  • a source high-Q magnetic resonator coupled to a power source and generating an oscillating magnetic field;

    at least one device high-Q magnetic resonator configured to convert said oscillating magnetic field to electrical energy used to power a light coupled to the at least one device resonator; and

    at least one repeater resonator;

    wherein the repeater resonator is positioned further from the source resonator than the device resonator and improves the power transfer efficiency between the source resonator and the device resonator.
