Switched Chrome Bulb Holder with internal Earth.
Brass construction with switch, built-in earth point for safety and cable grip.
Built in switch means there is no need for a cable mounted on off inline switch.
It may be hard to run a 3 core cable up the arms of a Anglepoise 1227. The best chance is a fabric
wrapped one at 0.5mm.
Internal earth is much better looking than an external connection.
This is a metal bulb holder that must be earthed.
Good quality, UK made and CE stamp.
Needs 10mm cord grip.
