I have tons of boring recessed lighting throughout my home. One day in the basement I saw the shape of the filter from the shop vac and it gave me a thought that it may be the correct size for the recessed light opening. The size was correct. I purchased a regular recessed light opening and attached it to the bottom. It lit and then all that had to be done was to hand decorate the new recessed hanging paper lamp. It looks great when lit and is a little something different than the other 25 recessed lights.
