This Nickel BC Switched Lampholder 10mm Entry With Stem Lock 5640318 comes with an internal earth connect rather than one on the side. It
also has a shade ring to hold a lamp shade with a 28/30mm diameter hole.
This lampholder is a standard B22 lampholder except it has a lock collar at the bottom with an internal locking screw.
This prevents any unwanted untwisting of the lampholder.
Comes complete with a shade ring.
As this is a metal lampholder, ensure you use a 3 core mains flex to provide an earth connection to this lampholder.
