Hi,

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
Faustino

Safety!
The transformer is a minor disadvantage compared to the benefits in
certaincicumstances.

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.
