An energy consumption device includes a housing that supports a first and second terminal. An energy consuming module, which may include a light emitting diode array, is supported by the housing and is thermally coupled to a thermal bridge that extends below a lower surface of the housing. A cover can be positioned so as to secure the energy consuming module between the cover and the housing. A plurality of magnets can be configured to secure the energy consumption device to a rail that supports powered contacts so that the first and second terminals engage the powered contacts and the thermal bridge is pressed against the rail.
