A representative apparatus controls current supplied to solid state lighting, such as light emitting diodes. The apparatus includes an inductor, a memory adapted to store a plurality of current parameters and a controller. The controller is configured to control a power source to supply current to the inductor to start an energizing cycle, monitor an inductor current level, reduce the inductor current level in response to the inductor current level reaching a predetermined peak inductor current, and increase the inductor current level in response to the inductor current reaching a predetermined minimum current is reached. In at least one embodiment, the controller modulates a current provided to the solid state lighting such that a DC average current level is substantially proportional to one-half of a sum of the predetermined peak current level and the predetermined minimum current level.
