Abstract: Devices, systems and methods of converting the necks on lamp shades into threadable couplers that allow the shades with the couplers to be screwed onto the exterior threads on light sockets, such as those types of sockets found on wall mounted and ceiling mounted candelabras and ceiling fans. The couplers can include plate members that are fastened in a sandwich configuration on both the inside and outside of the neck portion of the shade with the sandwiched plate members having an interior threaded surface. Modified lamp shades can be screwed to exterior threaded light sockets on candelabra lights, pendant lights, ceiling fan lights, and any other type of lamp sockets that have removable lamp shades.
