Systems and methods for multiple band visible light disinfection are disclosed. In some examples, a disinfecting light is generated by combining two different disinfecting wavelength ranges of light. A lighting device may comprise a first light source that generates light in a Soret band. The lighting device may further comprise a second light source that generates light in a Q band. The light in the Soret band and the light in the Q band may be combined to generate disinfecting light.
