Ultraviolet radiation is directed within an area at target wavelengths and/or target intensities. The target wavelength ranges and/or target intensity ranges of the ultraviolet radiation sources can correspond to at least one of a plurality of selectable operating configurations including a storage life preservation operating configuration, a disinfection operating configuration, and an ethylene decomposition operating configuration.

A thermally insulated door assembly includes first and second panes of light transmissive material, a light assembly, and a heat sink. The first pane and the second pane are spaced apart from each other by a separation gap to define an interior chamber. The light assembly is in the interior chamber between the first pane and the second pane, and is configured to generate light within the interior chamber. The heat sink is disposed within the interior chamber and coupled with the light assembly and an inwardly facing surface of the first pane. The heat sink is configured to conduct thermal energy generated by the light assembly onto an inwardly facing surface of the first pane and into the interior chamber such that the inwardly facing surface of the first pane and the interior chamber are heated by the light assembly.
