An exemplary system comprises a power regulator and an emitting apparatus. The emitting apparatus is typically attached to or integrated with a display object, such as a merchandise package or container. A support structure, such as a point of purchase display, typically contains or supports one or more power regulators and display objects. The power regulator comprises a controller and a primary inductor, and the controller is adapted to provide a voltage or current to the primary inductor to generate a first primary inductor voltage. The emitting apparatus comprises an illumination source and a secondary inductor coupled to the illumination source. The illumination source is adapted to emit visible light when the power regulator is in an on state and when the secondary inductor is within a predetermined distance of the primary inductor. In exemplary embodiments, the first and second inductors are substantially planar.
