I've been seeing recently the increasing offers of low voltage (12V)
lighting. At least one disadvantage is real: I need a voltage transformer
(and run the low voltage lines all over the house) to make it work. But
which are the advantage of these over conventional 110V lighting?.
Thanks in advance
The transformer is a minor disadvantage compared to the benefits in
12V lighting is not subject to some of the same codes of wiring as the 110V
stuff. Yu can runwires in places that would not be allowed. The wires are
thinner and easier for Joe Sixpack to handle. This is a major advantage for
outdoor applications for lighitng a patio or deck.
Well, actually the advantage is to the insurance company used by the light
manufacturer. There is much less chance that you, the consumer, will shock
yourself and sue the manufacturer. This is the same reason that all small
electronics devices have "power bricks" now.
Anmother reason most manufacturers have resorted to "power bricks" is
that UL only goes as far as the 120 volt component. I don't believe
that my printer is UL blessed, but the "power brick" is. Same with my
laptop. Saves time and money.
BTW, I bought a replacement cord for an old iron that I wanted to use
for softening glued veneer. Plugged it in and thought I had left my arc
welder on. When I opened it up the two conductors (an old style cord)
were connected together in the female connector. The UL tag on the cord
didn't even get singed.

Well, yes and no.
The advantage to the manufacturer selling in the U.S. in
using out-board power supplies is that they only need to get
the power supply UL listed, not the entire device, hence
saving significant money and time-to-market. In this way
they can also use the same supply on multiple devices for
further savings, or use different supplies for the same
device destined for different countries to gain even further

More lights on a circuit, easier wiring of lamps, can't electrocute
yourself by sticking your tongue in the lamp socket... :)
Biggest advantage is often size of fixtures. You can put
mood/environment lighting everywhere. Better is fiber optic for this,
but costlier and more difficult.
