Hook-on ceiling adapter E26 base conversion adapter Light bulb socket lamp With outlet plug attachment Used item. *As a bonus, I've added a light bulb-shaped bottle object, approximately 12cm long (photos 16-19)^^ This is a socket for attaching a lamp (light bulb) by plugging it into a square hook-on ceiling fixture, and it also has a ring for securing a shade (lampshade). You can easily change a hook-on ceiling socket to an E26 base without any construction work. It also comes with an outlet plug attachment, so you can use it as an emergency light during power outages or disasters with a portable power supply (portable power supply & light bulb not included, see photos 13-14). The outlet plug attachment is rare. Color: Ivory Please refer to photo 12 for the size. Please make your judgment based on the photos, and we look forward to your consideration if you accept no returns or exchanges. m(_ _)m
