A three-way solid-state light bulb is disclosed. Embodiments of the present invention provide power supply circuitry that allows a solid-state lamp or light bulb to work in a manner similar to that of a common three-way incandescent light bulb. The power supply can selectively receive the input voltage, usually AC line voltage, on first and second input terminals. In some embodiments, a control circuit is operable to influence a feedback loop by diverting current and/or in some cases alter a current sense resistance in accordance with the selective presence of the voltage at the first and second inputs. The light output of the solid-state emitter or solid-state emitters in the bulb is set in accordance with a selective presence of the input voltage.
