I'm sort of wondering what the difference is between the design of this wall mount light fixture and any typical ceiling mount light fixture as far as obtaining a UL listing would be?
Aren't the wires from the bulb sockets on most standard round ceiling fixture laid in the void between the ceiling [which could be made from combustible material like wood] and the fixture canopy and then enter through the opening of the box as opposed to through a KO or connector?
With the fixture in question, as long as the splices themselves are contained within the box and you caulk or otherwise seal around the base of the fixture to provide a weatherproof seal, don't you now have a fixture suitable for a damp location?
Generally even the instructions for listed wet location boxes state that appropriate sealing must be provided by the installer to obtain the damp or wet location rating. I guess it's up to the installer to determine the type or method of seal to be used.
