A light source is provided with extended persistence and reduced flicker characteristics by using a light capacitive filter. In general, a light source can include an illumination source which converts electrical energy into emitted light. The illumination source, however, is generally powered by an AC waveform, and the periodic variations inherent in the AC waveform may cause flicker in the emitted light. To reduce the flicker, a light capacitive filter is included in the light source to filter the light emitted by the illumination source and produce a light output with reduced flicker. In some examples, the light capacitive filter includes a medium persistence phosphor having a decay constant (or half-life) of between 1 milliseconds and 2 seconds.
