1. A control method for powering one or more dimmable lamps without flickering, each lamp including one or more light emitter device(s) and an electronic circuit that tracks a conduction angle of an AC power supply to vary light intensity of the light emitter device(s), the method comprising:
executing a sequence to alter the AC power supply to power the lamp(s), the sequence comprising:
interrupting the AC power supply to the lamp(s) one or more times per cycle of the AC electrical signal;
activating the AC power supply to the lamp(s) one or more times per cycle of the AC power supply, wherein the duration length of an activation is a conduction period; and
applying a load on the AC power supply to the lamp(s) at any time during a non- conduction period one or more times per cycle of the AC power supply, the load absorbing residual energy following one or more power interruptions.
