1. A method of reducing bactericidal counts, the method comprising:
powering a light source to emit emitted light having a chromaticity, said light source comprising a plurality of light emitters including at least one violet solid-state emitter and at least one phosphor, wherein said chromaticity is within a Duv distance of less than 5E-3 from the Planckian locus, wherein said chromaticity and said Duv are calculated using CIE 1964 10° CMFs; and
configuring said light source to illuminate a surface with said emitted light to reduce a bacterial count by at least a factor of ten in twelve hours.
