Dangerous small bayonet cap to small Edison screw lamp adaptors.04:33

I bought this adaptor from a UK ebay seller. It’s designed to convert a lamp with an SES base (Small Edison screw) to a SBC (Small Bayonet Cap) base which is quite common in the UK but has less variety of lamps available with that cap. And quite frankly this item is a total deathtrap. It leaves large areas of exposed metal that will be directly connected to the mains wiring and depending on which way round the bayonet cap end is inserted, will be either connected to mains neutral or mains live. The latter poses a high electrocution hazard as your fingers would naturally close onto the metal and be prevented from pulling off by the lamps globe.
The PROPER type of adaptor would have a guard ring around where the exposed metal is to prevent accidental contact.
Now, a special message for the complete CLOWNS who invariably post comments saying things like “This is safe because you should always turn the light fitting off before changing a lamp.” If a light fitting has two way switching or is wired incorrectly there’s no way of guaranteeing that it is not live when you change a lamp. It’s also debatable whether a table light should have exposed live metal under a shade where you might fumble for an inbuilt on/off switch.
