I made this by hand, prioritizing compactness. It's incredibly small. It's an ultra-compact size, unlike anything commercially available, just big enough to hold an LED light bulb. Hanging a large cord pendant over a dining table can feel oppressive, but with this ultra-compact shade that adheres closely to the ceiling, the room feels much more spacious. It accommodates E26/E17 base general light bulbs, as well as globe bulbs. This is a set of 4. When installed as a 4-light cluster, it creates a gorgeous atmosphere. Generally, these are integrated LED fixtures (Image 4, sealed type), and ones like this that allow for bulb replacement (Image 5, open type) are rare. The ability to simply replace the bulb when it reaches the end of its life, and the option to choose your preferred LED bulb, such as chandelier bulbs (Image 6), are also significant advantages. ① Secure the square-type hanging lamp socket to the shade with a ring. ② Attach it to the existing ceiling hook ceiling fixture by twisting it into place. ③ Set the E26/E17 type LED light bulb. ④ It's more cost-effective to proceed with the E26 specification and only use a conversion adapter when using an E17 bulb. Please purchase the square-type hanging lamp socket separately. Buying multiple units together results in a significant discount.
