Something's pretty fishy about this post. I spent a lot of time
in Wales and London both, and never came across a bayonet bulb on
anything run from the Mains.
I did see bayonets on some lab equipment in Wales, but those
weren't run from the mains. I think we're being led down the
proverbial path here, or:

Perhaps the OP would/could explain further?

My take is, if a desk lamp takes a bayonet, it's not run from the
mains; there is a transformer or ballast of some sort in that
appliance. And desk lamps fit that category.
Maybe the OP is talking about non-mains non-direct connectons.
A lot of outdoor lights, etc. are run on LV via transofrmers et
al.
