My main room light fitting has 5 G9 40watt bulbs. One has been arcing a bit and has made a slit in the contact.
I cannot work out how to remove the bulbholder (although as yet I have not taken it off the ceiling - it could now be the wires holding it.
By sqeezing the threaded part I have been able to release a bayonet type of fixing but the holder does not withdraw a useful amount (perhaps the wires) . However, I have not seen a suitable matching holder. Can anyone make any suggestions?
