1. An apparatus for power conversion, the apparatus couplable to a first, phase-modulated dimmer switch coupled to an alternating current (AC) power source, the apparatus couplable to a solid state lighting, the apparatus comprising:

  • a switching power supply;

    a first adaptive interface circuit comprising an at least partially resistive impedance to conduct current from the first switch in a default mode; and

    a second adaptive interface circuit to create a resonant process when the first switch turns on.
