A circuit to control power to a light-emitting device connected in parallel to an inductive device switching current to the parallel combination repeatedly between a charge state during which said inductive element is charged and a discharge state during which said inductive element is discharged through said light-emitting device. A method to control power to a light-emitting device to switch current to a parallel connection of an inductance device and a light-emitting device repeatedly between a charge state during which said inductive element is charged and a discharge state during which said inductive element is discharged through said light-emitting device.
