To do that you need the full set, 2-way bulb adaptor & BC plug. Pvc
flex should not be used in the BC plug, only rubber, since the flex
sits directly on the hot bulb. The worst part of these things wasnt
the adaptor/plug/cable, which was dodgy enough, but the fact that
users would handle the top end of the fitted bulb holder, which in
the later years of round pin wiring had frequently lost some if its
(single) insulation, so you were fumbling with bare uninsulated
mains wires that you couldnt see too much from below, with the bulb
in your face, while standing on a chair or bed.

Maybe thats why iron beds declined in popularity, darwin effect....

I have never understood how it is still permitted to have a
lampholder like in the OP

The way the lampholder is suspended depends on the grip of the actual
screw-fittings on the bare wires.

If a moderately heavy lampshade is used then the whole thing seems to
be asking for trouble.

Does the US have ceiling pendant lampholders as dodgy as this?

There is so much safety in electrical products these days that I just
wonder how this sort of lampholder is not obliged to have a decent
flex grip in it.
