These are brand new, never been used, dusk till dawn photocells!! Boxes are slightly damaged, or no box so they cannot be put on the shelf for sale. That’s why they are at an excellent price up here! They are for any outdoor area light, or floodlight, that accepts three prong plug and twist to lock photo cells. Buy as many as you would like with combined shipping to the 48 lower states!  please look at my other post to see yard lights, light arms, light kits
