Abstract: An LED lighting system may include one or more light-emitting diodes and one or more power management modules. Components of the LED lighting system may be selected and arranged, for example, to match a load voltage to an operating voltage. Matching the load voltage to the operating voltage may enable efficient use of power by the LED lighting system. A method of selecting components of the LED lighting system is provided. For example, the components may be selected based on a target luminance and a given operating voltage. The method may be facilitated and/or implemented with a computer.
