I bought a nice LED ceiling light for my entryway to replace the square recessed light. I didn't want to redo the 10x10 inch hole in the ceiling and replace it with a proper junction box. My new light is big enough to cover the hole in the ceiling. I used this adapter to just plug it into the socket of an old light fixture and then use a couple of mollys to attach the new light fixture to the ceiling. The male and female arrangement of this adapter allowed me to plug one end into a new mount and the other end. the other to the old outlet. Then it was just plug and play during installation. No need to hold a new jig in one hand and try to manipulate the wire nuts with the other. A simple but effective upgrade.
