Abstract: Adjustable light emitting diode lighting assembly, kit and system and method of assembling an adjustable light emitting diode lighting assembly. The adjustable light emitting diode lighting assembly comprises a mounting can adapted to be mounted in a housing and an upper locking ring adapted to be mounted to the mounting can. A lower base ring is spaced-apart from the upper locking ring. An adjustable collar coupled to the upper locking ring and the lower base ring and interposed therebetween is provided for adjustably supporting a light emitting diode module over a plurality of light distribution angles. Conductive, radiative and/or convective heat sinks are provided for removing heat produced by the light emitting diode module to maintain luminous efficiency and service life of the light emitting diode module.

Abstract: A retrofit kit for a gutted fluorescent light fixture includes a self contained source of visible radiant energy configured to replicate a light pattern generated by the gutted fluorescent light fixture but with improved luminance; where the self contained source of visible radiant energy is adapted to be coupled to a universal source of electrical energy and supported by the fluorescent light fixture without modification after the fluorescent light fixture has been gutted of its ballast, electrical sockets, fluorescent bulb and ballast cover.
