Questions about Paulmann Cover-it panel

I have a concrete ceiling and had to drill holes to secure the base plate with screws. The light unit then twisted onto the base plate. However, two very strong spring clips are supplied with the unit and I suspect that these could be used to keep the whole unit in place should you have a plasterboard ceiling where the clips could be position through a hole in the ceiling. They are adjustable across the base plate and should fit any size hole.
