A compact recessed lighting system is provided. The lighting system includes a light source module, a heat sink, a lens, a set of electrical contacts, and a set of trims. Each of these elements of the lighting system may be coupled to an integrated interface module. The recessed lighting system provides a reduced set of components while ensuring adaptability and easy installation into a structure. In particular, by including an integrated interface module that allows the light source module, the set of trims, the lens, and the heat sink to be easily replaced with minimal tools and minimal fasteners, the recessed lighting system described herein provides a more efficient and user friendly design in comparison to traditional systems.
