I have a customer who wants some of the undercounter "puck lights" installed. I have looked at some and they have a cord and plug on them. How have some of you installed these without having to run a cord down the wall to an outlet? Is there room inside the light to make a connection if the cord was removed? It sure doesn't look like it, in the ones I've seen.Thought about mounting a receptacle in the cabinet, and running the cord up through the bottom of the cabinet to the receptacle, but that takes away from the space in the cabinet for dishes etc. Any input would be greatly appreciated. Thanks.. Steve
