1. A method of illumination and deactivation of bacteria in an area, comprising:
emitting white light from a first source in a luminaire in the area;
during the white light emission, emitting pulses of visible cleansing light of one or more wavelengths that deactivate a bacteria, from a second source in the luminaire separate from the first source, wherein the emitted visible cleansing light is combined with the emitted white light from the first source and output from the luminaire; and
during each pulse time of emission of a pulse of cleansing light from the second source, controlling the white light from the first source and the visible cleansing light from the second source such that for both a human-occupied state and a human-unoccupied state of the space illuminated by the luminaire, an intensity of pulse emission of the cleansing light from the second source is higher than an intensity of the white light emission from the first source,
wherein the pulses of visible cleansing light are emitted at an irregular rate and interval over a time period to apply a deactivation dosage of the cleansing light to the bacteria within range of the emissions.
