This E27 Half Threaded Black Lampholder comes complete with an internal earth connect if needed. It has a threaded skirt with a fixed shade ring so an additional shade ring will be required. The base fixing in 10mm and has a locking screw on this fixing to stop it twisting when the lamp is removed. The ES Half Threaded Black Lampholder is also known as a European Lampholder.
Height is 54mm and the diameter is 39mm on the thread and slightly wider at the fixed shade ring.
If using this lampholder with a 2 core flex on a metal fixing add an isolator in the base to help the insulation. See the isolator below or click here.
Select the Plastic Cap option if you need a fully isolated cap or are going to add a cord grip and use the lampholder as a pendant lamp. With the 2 options you can have either a metal 10mm thread or a plastic thread in the cap. With the plastic thread there is no locking screw so a spot of super glue is ideal to stop the lampholder twisting when being used.
