A lighting system and method for generating an output light beam representative of a target natural light are provided. The lighting system includes a plurality of solid-state light emitters each emitting a light sub-beam having an individual spectrum. The individual spectra of the solid-state light emitters collectively cover a visible portion of the natural light spectral profile and exclude infrared and ultraviolet components. The lighting system further includes a combining assembly combining the light sub-beams into the output light beam. A control module controls an intensity of the light sub-beam from each of the solid-state light emitters such that the resulting combined spectral profile of the output light beam is representative of a natural light spectral profile of the target natural light over its visible portion.
