A LED-based lighting fixture for Controlled Environment Horticulture (CEH) includes a module having an inspection light system to facilitate inspection of one or more plants. The inspection light system may emit inspection light to illuminate the plants during the plants' night cycle where the intensity, wavelength, and/or duration of the inspection light may be adjusted to avoid disrupting the plants' night cycle. The lighting fixture provides a mechanical interface to mount the module and an electrical interface to provide electrical power and data communication with the module. The inspection light system may be communicatively coupled to a proximity sensor that activates or deactivates the inspection light system depending on the presence of a grower near the lighting fixture. Additionally, the modules may be deployed in arrays of lighting fixtures and used to convey additional information (notifications, environmental data) to the grower by emitting light at different intensities and/or wavelengths.
