"how to see in the dark"
From fire to electricity..... and than what
having discovered electricity, man has made giant steps
Part of these discoveries have been dedicated in length to
lighting dark places and night hours, where he has to live
For example the lighting of streets, houses, mines, ship
headlights, airports, only to mention a few in an infinity
of technical improvements, up to sophisticated moon and outer space
But lets simply remain on Earth and think of our
houses, where we know we can arrive in all security as the
streets are well light.
To say the word electricity is quickly done, but difficult to do
and specially in an economical way.
do not want to linger on how to light, as an infinity of
lamps exist and each with particular features for any kind
of use, we would like to concentrate on what we produce
and that is power source systems.
One of the oldest, if not the oldest in alternate current
(AC), is the series system, and now the most commonly used
is the parallel system.
What is the difference? The series system counts a n
number of lamps connected in series, built for a specific
current (normally 6, 10, 15, 20 A), all have the same
lighting level as they work directly from the current,
which is constant.
The parallel system is built up of a double line, from
which a n number of lamps, designed
for a precise voltage (normally 230 V), but which will
never have the same lighting level, caused by tension
drops, between the first and last.
VARAT decided to retrieve the old system, almost
completely abandoned in time, certain that a 100 years of lighting history
experience is not to be
forgotten. VARAT has married the old concept along
with new electronics, conceiving a very valid,
innovative and economical system, saving thus on managing
