Lampshade Fittings & Lightbulb Guide

Lampshade Fitting Guide – UK & EU Compatibility

All Berry & Grouse lampshades are designed for easy compatibility with both UK and EU lamp fittings. Every lampshade includes a universal fitting ring (also know as a reducer ring), which connects your lampshade to your light fitting.

Our lampshade fitting ring comes with a 29mm converter (reducer) ring, making it ideal for standard UK lamp bases. Need it for a European lamp? No problem—simply remove the reducer ring to expand the fitting size to 40mm, suitable for standard EU lamp fittings.

​

💡 Positioning Tip: The light fitting sits approximately 40mm inside the shade—either at the bottom (for table/floor lamps) or top (for ceiling pendants), depending on how your lampshade will hang.

DUPLEX FRAME LAMPSHADES - EMPIRE & CONICAL 

Our Empire and Conical lampshades are built on a Duplex frame, offering flexible fitting options. To use them with a table lamp or floor lamp, you’ll need a carrier ring (included with your purchase). For ceiling pendant lights, use a spider fitting, which we also supply based on your order specifications.

​

If you need your lampshade to sit higher or lower than our standard fitting allows, contact us—we’re happy to help recommend alternative lampshade carrier fittings to suit your lamp base.

USA LAMPSHADE FITTING

For USA Harp/Finial fittings you will require a Duplex Converting Kit to connect your lampshade to the top of the light fitting. 

The Duplex Converting Kit is a three part system comprising of:

  • Spider Fitting - Lamp Shade Duplex Adaptor

  • E27/E26 to B22/E14 Lampshade Reducer / Converter Adapter

  • Converting Washers – with a 110mm centre hole
    (Fits standard 1/4" and 3/8" harp stems)

​

Conversion chart with imperial and metric measurements:

Inches    Metric
1/4"     6.35 mm
5/16"   7.95 mm
3/8"     9.53 mm
Our system works with these sizes, but If the Harp stem is bigger, you can make the hole in the washer bigger to fit.

fabric & light transmission

Different lampshade fabrics affect how much light passes through:

  • Lightweight fabrics (e.g. linen, thin cotton) = More light diffusion

  • Heavy fabrics (e.g. wool, thick cotton) = Softer, dimmer lighting

For mood lighting or brighter rooms, choose accordingly to suit your space and ambiance.
