I see that there are some recess light housing designed for
remodeling, so you just cut a hole say 6" in diameter, hook up the MC
cable, then push the housing up and it will lock into the ceiling
sheetrock with the clips, see picture link below:

My question is once the clips snaps in place and the housing is
installed, is it still possible to remove it? Is the clip unlockable
from the inside of the can, or you have to go up to the attic or cut a
hole next to it to reach in to remove it?

Thanks,

MC
