A lighting device configured to deactivate pathogens in an environment. The lighting device includes a housing, means for mounting the housing to a surface in the environment, one or more first light-emitting elements arranged in the housing and configured to each produce disinfecting light having a wavelength in a first range of wavelengths, and one or more second light-emitting elements arranged in the housing and configured to each produce disinfecting light having a wavelength in a second range of wavelengths different from the first range of wavelengths. The disinfecting light produced by the first light-emitting elements and the disinfecting light produced by the second light-emitting elements mix to form a combined light, the combined light being visible light other than white light.
