1. An apparatus comprising:

  • a controller to provide compatibility between a load and a secondary winding of an electronic transformer driven by a trailing-edge dimmer, wherein the controller is configured to;

    predict based on an electronic transformer secondary signal an estimated occurrence of a high-resistance state of the trailing-edge dimmer, wherein the high-resistance state occurs when the trailing-edge dimmer begins phase-cutting an alternating current voltage signal; and

    operate in a high-current mode for a period of time immediately prior to the estimated occurrence of the high-resistance state.
