1. A lighting apparatus, comprising:

  • a housing;

    a thermally-conducting circuit board located within the housing and having two opposing sides and an electrically-insulating layer on at least one of the two opposing sides;

    at least one LED light source thermally coupled to the circuit board to conduct heat from the LED light source to the circuit board during operation, wherein the LED light source is connected to the circuit board to receive electrical power from the circuit board;

    a compound configured to allow transmission of at least a portion of light output of the LED light source, the compound being located in a space between an interior surface of the housing and the circuit board and configured to provide mechanical contact with the circuit board, the LED light source and the housing such that heat is conducted from the circuit board to the compound during operation;

    at least one spacer located within an interior portion of the housing, wherein the at least one spacer is configured to absorb mechanical shock introduced into the lighting apparatus; and

    a power supply circuit for providing electrical power to energize the LED light source.
