WideBAMBOO Lampshade Fitting Guide for North America
Welcome! We understand that finding the perfect lampshade goes beyond just design—it needs to fit your lamp base perfectly. This guide is specifically designed to help our North American customers ensure a perfect match between our E27 lampshades and your lamp bases.
Follow these straightforward steps to confirm compatibility and enjoy your new WideBAMBOO lampshade with complete confidence.
Understanding Our UNO Fitter System
1. Every WideBAMBOO lampshade features a UNO fitter attachment system. This is a flat metal ring integrated into the lampshade's frame, designed to sit directly on your lamp's socket (where the light bulb screws in).
2. The lampshade is secured in place by a separate screw-on ring that typically comes with your lamp base. Our UNO fitter ring has an inner diameter of 4cm (approximately 1.57 inches), which is the international standard for E27 sockets.
Key Specification: Fitter Ring Inner Diameter = 4cm (1.57 inches)

Identifying Your Lamp's Fitter Type
Before purchasing, it's essential to identify which fitter system your lamp uses. Most lamps use one of three common types, but our UNO fitters are NOT compatible with Harp & Finial systems.
| Fitter Type | Description | Compatibility |
|---|---|---|
| UNO Fitter | Your lamp has external threads on the socket for a screw-on ring. This is the most common modern style in North America. | YES! Perfect match for our lampshades. |
| Harp & Finial Fitter | Your lamp has a U-shaped metal frame (harp) surrounding the bulb. The shade sits on top and is secured with a decorative screw (finial). | NO. Our lampshades lack the required top ring. |
| Clip-On Fitter | The lampshade has wire clips that attach directly onto the light bulb itself, typically used for smaller chandelier shades. | NO. Our lampshades are too large for this system. |

The E27 vs. E26 Socket Difference
1. This is the most important consideration for North American customers. While E27 (international standard) and E26 (North American standard) light bulbs are interchangeable, the outer diameter of the lamp sockets themselves can vary.
2. Our 4cm UNO fitter is designed to the E27 international standard. Many modern North American lamps use sockets that accommodate this size perfectly, but some certain manufacturers' lamps may have slightly smaller socket housings.
For E27 Sockets (International Standard)
Perfect Fit Guaranteed! If you have an E27 socket, our lampshade will fit flawlessly. No additional steps needed—order with complete confidence.
For E26 Sockets (North American Standard)
Quick Check Recommended. Please proceed to the measurement step below to ensure optimal fit and stability.
Simple Measurement Guide for E26 Sockets
1. This quick measurement will confirm whether our lampshade will fit your E26 lamp base perfectly. You'll need a ruler or measuring tape and just two minutes of your time.
Measurement Steps:
- Remove the screw-on ring from your lamp's socket (if attached)
- Using a ruler, measure the outer diameter of the threaded portion of your lamp socket
- Compare your measurement to our 4cm (1.57 inch) fitter diameter
2. If your socket measures very close to 4cm (1.57 inches): Excellent news! Our lampshade will fit snugly and securely. You can proceed with your order with confidence.
3. If your socket measures significantly smaller than 4cm: The lampshade ring may not sit perfectly centered, which could result in a slight tilt or instability. However, there's an easy and affordable solution available.
The Perfect Solution: Lampshade Reducer Ring
1. If your measurement indicates a smaller socket, a Lampshade Reducer Ring (also called an E27 to E26 adapter) provides an elegant solution. This simple accessory clips into our 4cm fitter, reducing the inner diameter to create a snug, perfectly centered fit on smaller E26 sockets.
2. This adapter completely eliminates any wobbling and ensures your lampshade sits beautifully level. It's a standard lighting accessory that's widely available and inexpensive.
Where to Find Your Adapter
1. To maintain the best value for our global customers, this North America-specific adapter is not included with the lampshade. However, it's readily available from most online retailers and local lighting supply stores.
2. We recommend searching using these terms for the best results:
