This section will help you repair an existing lamp with a broken lampholder.
This will apply to any type of lamp base as the principle will be the same.
Firstly remove all the parts from the old lampholder so you leave just the male thread that the old lampholder was screwed onto and the wires coming out the top.
Now measure the diameter of the male thread, in most cases it will be 10mm or 1/2" (12.7mm) but there are a few odd ones out there.
Decide now the type and style of lampholder you need like, Metal or Plastic, BC (bayonet with the 2 pins) or ES (Edison Screw) and of course with or without a switch. Below we have shown the different types of lampholder that you may need. Dont forget to note the diameter of the thread as this will be refered to as the "screw entry" size. Also an important note, if you only have 2 wires then you cant use a metal lampholder as this will need to be earthed.
BC Lampholders, Switched and none switched
ES (E27) and SES (Small es ) Lampholders

1) it is held in by a screw in the middle of the fitting to the shade.
2) the wire comes out of the side of the head
3) It is a 20mm screw bulb fitting
