1. A layered structure for use with a high power light emitting diode system, comprising:

  • an electrically insulating intermediate layer interconnecting a top layer and a bottom layer;

    the top layer, the intermediate layer, and the bottom layer forming an at least semi-flexible elongate member having a longitudinal axis and a plurality of positions spaced along the longitudinal axis, the at least semi-flexible elongate member being bendable laterally proximate the plurality of positions spaced along the longitudinal axis to a radius of 6 inches, twistable relative to its longitudinal axis up to 10 degrees per inch, and bendable to conform to localized heat sink surface flatness variations having a radius of 1 inch; and

    the top layer being pre-populated with electrical components for high wattage, the electrical components including at least one high wattage light emitting diode at least 1.0 Watt per 0.8 inch squared.
