I want to replace some can lights with some hanging pendant lights. Is there any easy way or will i have to fill the existing holes -6" to add new light boxes which are what 4 1/2 inches ? any ideas so i wont have to patch because I need the lights in the same places ? does that make cents ? I guess i am wondering if there is a trim plate to cover between the 4 inch light box and the 6 inch hole ? But I think I know the answer Its just that its over a kitchen island on a 15 foot ceiling - hard to get to - easy to patch !
