Adjustable wall lighting as far as the eye can see. The SONNEMAN Lighting Mounting Rail Kit for Aileron LED Flat Panel Wall Sconce adds even more versatility to the already versatile fixture by seamlessly combining multiple separate wall sconces into a longer single unit. This rail kit includes top and bottom wall mounted rails (in coordinating finishes) that can support multiple Ailerons in a row without compromising their individual adjustability. In other words, you can still adjust each louver to have one direct light upward, one downward and one right in the middle. And then, change them up whenever you need.
