Disclosed are examples of hyperspectral imager-equipped lighting devices that provide general illumination supplied by artificial or natural light, and that also detect environmental conditions in the environment around the lighting device. The hyperspectral imager detects light within a contiguous data from the environment in the vicinity of the lighting device. In response, the hyperspectral imager generates image data representative of the spectral intensity distribution (e.g. intensities of a continuous range wavelengths in the optical spectrum) of the detected light. A controller may analyze the image data generated by the hyperspectral imager and may initiate action based on, or outputs a report indicating, an environmental condition detected by the analysis of the generated image data.
