Light sockets

Something that has puzzled me for years.


Bayonet cap and Edison screw light bulbs can be removed without tools thus exposing potentially live terminals and presenting a distinct shock hazard.  made worse by the fact that you often need to stand on a chair to remove the bulb.   There are millions of these installed yet the regs seem quite happy with the situation.

    Bayonet lamp holders have been in general use for over 100 years and in practice have a good record of safety and reliability.

    Screw in types also, though arguably less safe.

    The great merit of BC types is that the lamp can not work loose under vibration.

    Screw types have the merit of being inherently polarised and also that the light may be extinguished by partly unsrewing the bulb.


    Neither type is meant to be used on more than 250 volts.
