A lighting device includes a first light source configured to generate light for illumination of a space and a second light source configured to generate light of a particular wavelength independently from the first light source. The light generated by the second light source is output at a sufficient intensity so as to reasonably expect to support an intended benefit other than illumination of the space. The first light source and the second light source are integrated into the same lighting device. The lighting device includes an optical element coupled to the first and second light sources that is configured to produce a light output of the lighting device. The lighting device outputs the light for illumination of the space and the light of the particular wavelength for the other intended benefit from the second light source via the same output of the lighting device.
