Standard lamp is fed by 2 core flex through metal tube seen in background. The bulbholder is plastic so question is should it be earthed. Item bought from Homesense.
Not sure if its double insulated, my daughter sent me the photo asking if I could fix it back together, she's bringing it round tonight so will check. It's to be used in a shop, I just thought it was suspect with the cable though exposed metal. Will report back when I've seen it. (thanks for reply)
You tend to see it more nowadays, also with ceiling lights, the holders seem to be all plastic, including the thread inserts and the makers seem to suggest that negates the need for earth, i guess, because, the cable is generally double sheathed where it passes through the metal and any bits of the assembly that screw into the lampholder entry tend to be plastic rather than metal.
