Abstract

A light comprising a housing, a light source, a light source mounting means and a heat sink for dissipating heat generated by the light source, wherein the light is configured to transfer heat energy from the light source to the heat sink and the heat sink is disposed within the housing such that the heat sink dissipates heat energy within the housing.
