A lighting system (100) is presented that includes a replaceable illumination module (10) removably coupled to a base module (15). The replaceable illumination module includes one or more solid state lighting elements (14) on a printed circuit board (18) electrically and thermally connected to the base module. The base module may include a heat sink, where the heat sink is in thermal contact with the replaceable illumination module, and dissipates heat generated by the one or more solid state lighting elements during operation of the lighting system. The replaceable illumination module may also include one or more beam conditioning elements (12) for generating a specified beam. The lighting system may be connected to an automated control network and may be automatically controlled thereby, or may be used to control some other system. The heat sink may be generated via a dynamically controllable extrusion die.
