This is a hanging lamp socket. It's the type that can be used with small light bulbs. I'm selling it because I ordered the wrong size. It has been opened, but it's unused. I tried to attach a shade, so there are minor scratches that are not noticeable. Please check the condition in the images. Thank you. ● Compatible with E17 type bulbs up to 60W. ● Includes a shade fixing ring, so you can attach your favorite shade and enjoy an original light. 【 Specifications 】 ■ Bulb base: E17 ■ Shade hole size that can be fixed: 30~45mm ■ Body weight capacity: Up to 3kg ■ Compatible bulb: Up to 60W ■ Materials: Body...
