The E12 Shade Ready Socket in ivory is an off-white thermoplastic e12 socket with threads and removable shade ring that is designed to hold candelabra specific shades. This socket is intended for candelabra bulbs and is not compatible with standard e26 base bulbs, so be sure to confirm the size of the socket and bulb that you need for your project before ordering. But, if you are working with a chandelier or decorative fixture with an e12 bulb base and a shade, then this is the socket for you!
