Even the simplest things.....
Added 2022-12-27 02:53:40 +0000 UTCThis is particularly annoying, and a good example of how many products are made by small companies using standard components without realising how subtle differences can be dangerous.
Perhaps the manufacturer of the plastic adaptor does a specific bayonet cap version without the side tag, but the person who assembled this just assumed it would fit any similarly sized metal base.
Aside from potentially leaving exposed live metal, this adaptor can introduce a very insidious neutral/earth fault into a wiring system that can have weird RCD/GFCI tripping effects on unconnected circuits.

Wow.

2023-01-03 00:46:01 +0000 UTCI had that experience with a B22 Lighting Ever brand LED bulb 9 years ago - Tested it in one room and worked fine, then tried it in another with a metal lampshade and blew the lighting circuit fuse. No spare 6A bottle fuse that evening either (we've since upgraded the consumer unit to circuit breakers). Thinking it might be a faulty light socket, I tried it in a table lamp and it tripped the RCD. Finally tested with a multimeter and sure enough one pin was connected to the bayonet cap.
