The lampshade ring converter is made of hard and solid plastic, sturdy, not easy to deform and durable. Dimensions: Outer diameter: approx. 55.8 mm; inner diameter: approx. 39 mm. Note: When measuring the diameter of the round head of your bulb, be sure to choose the appropriate reduction ring. Easy installation: no tools required. By turning the reduction ring to fix the bulb and lampshade, you can adjust the lamp to the size of the bulb. Stable attachment without loosening: the close connection between the bulb and the lampshade prevents movement during use, ensuring safe lighting. Smooth surface and no burrs: Polished edges avoid scratching the lamp holder or lampshade, thus preserving the integrity of your fixtures.
