Waveform management systems and methods for ballasts are provided. The system includes a lamp, a ballast, a first interface, a storage unit, and a processing unit. The processing unit obtains at least one first waveform from the storage unit, and writes the first waveform to the ballast via the first interface. The processing unit transmits an illumination signal to the ballast via the first interface, such that the ballast controls the illumination of the lamp according to the first waveform.
