I read in sci.electronics.design that George Bray
arguments, but since it's a safety of life issue, I will go the extra
kilometre.
The Christmas tree lights have to be designed to be safe because if they
are not, they don't pass the safety tests and either cannot legally be
marketed or no retailers will stock them, depending on which country you
are in.
There is a LOT of difference between deliberately removing a cover and
just touching some wiring.
There was a well-publicised fatality to a 9 year old girl a while back
in UK. She stood on a metal strip on the floor, in bare feet, and
touched the base of a table lamp that had only a 2-core cable and an
internal fault.
There was another, most bizarre, one a few years earlier, when a man was
electrocuted in the bath. His wife was using an electric iron in the
kitchen and put it down on a metal sink with draining board. She was
insulated from Earth, so had no idea that the body of the iron was live.
The current went up the hot water pipe into the bath and thence to the
cold pipe, but enough went through the water to prove fatal.
Fatal accidents are mercifully rare, but because it's impossible to
foresee all the possible circumstances in which danger can arise, it is
necessary to be extra careful.
I hope you have used the 12 V solution.
I don't really see why I should bother to answer your ill-founded
arguments, but since it's a safety of life issue, I will go the extra
kilometre.
