LEDs
are
an
astounding
new
invention
that
will
soon
replace
almost
all
other
light
sources
on
the
planet.
Because
they’re
unlike
the
light
bulbs
you’ve
known,
choosing
and
using
them
successfully
requires
a
new
set
of
skills
and
knowledge.
Patented
by
a
GE
engineer
in
1962,
LEDs
were
such
an
astounding
invention,
other
engineers
in
the
company
called
them
"the
magic
thing."
Originally
used
as
tiny
red
dots
to
indicate
a
device
was
turned
on,
it
took
another
20
years
to
figure
out
how
to
make
LEDs
in
other
colors.
And
more
time
to
make
them
brighter.
All
those
problems
have
been
solved
now.
They
use
about
one-tenth
the
electricity
to
produce
the
same
brightness
incandescent
lights
would.
They
don't
get
hot,
so
they
don't
increase
air
conditioning
costs.
And
their
life
expectancy
is
30
to
40
times
longer
than
standard
light
bulbs.
They
have
a
few
limitations,
and
you
should
know
more
about
them
before
you
start
converting
your
lighting
to
LEDs.
That's
what
this
book
is about.
