For Lamp shades weighing less than 2 kg you can use a cord grip lampholder with shade rings to hang your shade. For shades over 2kg you need to support the flex by using some lighting chain and therefore need a lampholder with a hook and shade rings to hang your light shade. Then choose between a Bayonet Cap version with shade rings for a shade with a 32mm -35mm hole or an Edison screw version with shade rings for a shade with a 38mm – 45mm aperture.

This is sold in max of 10m single length. If your drop is more than that, lengths of chain can be joined using an S hook. Max shade weight is 5kg using a single hook. Please see our Weight tolerance FAQ if your shade is heavier than 5kg.
