E27/E26 to B22/E14 Lampshade Reducer / Converter Adapter ID: 3370

E27/E26  to  B22/E14  Lampshade Reducer / Converter Adapter – ShadeCore®

Our premium ShadeCore® converter allows shades with an E27 or E26 Edison Screw utility fitting to be used with lamp holders featuring a smaller B22 Bayonet Cap or E14 Edison Screw fitting.

It is an ideal solution when your chosen lampshade has a larger centre aperture than your lamp holder. Rather than replacing the shade or altering its frame, simply fit the reducer into the existing ring to create a smaller, compatible opening.

Perfect for new lampshades, handmade shades, replacement projects and imported lamp fittings, the removable adapter gives you greater flexibility when matching a lampshade to a table lamp, floor lamp or ceiling pendant.

You can rely on ShadeCore® lampshade frames for strength, accuracy, and professional results every time.

How do I use a Converter?

1. Gently squeeze the adapter and insert it into the centre of the lampshade frame. Release it once correctly positioned, ensuring that it sits securely and evenly within the existing E27 or E26 aperture.
2. The lampshade can then be fitted to a compatible B22 Bayonet Cap or E14 Edison Screw lamp holder.
