Fluorescent Lightings
You may be used to your standard watt light bulb. But nowadays
it seems that fluorescent lightings are really gaining
popularity.
Unfortunately, over the years fluorescent lightings have carried
the negative stigma that they provide flickering, sickly,
green-tinted, institutional-like, headache-inducing, noisy
light. But, those lights that used to be favored only for
lighting the garage are making their way into other rooms.
Today, the way of fluorescent lighting has changed. It is not
only one of the most efficient options offered, giving the
longest-lasting bulb, but it also comes in a variety of colors,
types, and sizes. And, best of all, thanks to the new electronic
ballasts, they are very quiet.
But you may wonder what exactly makes a fluorescent light a
fluorescent light.
Fluorescent lightings are phosphor-coated, glass tubes that are
filled with an inert gas and also a small amount of mercury.
Since different brands also can have different mixes of the
gases that are inside, fluorescents produce a wide assortment of
color light that can easily match the warm glow often given off
by incandescent.
In order to operate correctly, all fluorescent lightings need a
controlling ballast. The ballast alters the electric current
that flows through the fluorescent tube, activating the gas that
is inside, causing it to glow. Newly developed electronic
ballasts have the ability to eliminate the once annoying flicker
and buzz that was so commonly associated with old magnetic
ballasts, which were also quite a bit heavier and less
efficient.
Now there are even more impressive improvements to the design of
fluorescent lightings. In order to create the same amount of
light that is created by an incandescent bulb, a fluorescent
tube uses only ¼ to 1/3 of the energy. In addition, fluorescent
lights last 10 to 15 times longer, about 10,000 hours or even
more.
When these new designs were introduced in the early 1980s, they
definitely revolutionized lighting. Compact fluorescents, a
variation on the fluorescent tube, works the same way. The only
difference is the tube has been made smaller and is folded over
in a way that it makes them fit into spaces that are designed
for incandescent bulbs, with even a screw base that fits a
normal light bulb socket. In addition, they operate on a quarter
of the energy that is used by incandescent, also lasting ten
times longer.
Since fluorescent lightings last so much longer and use less
energy, they can really help you to reduce your monthly energy
bill. By replacing just 25 percent of your highly-used lights
with fluorescents, you can cut your energy bill nearly in half.
There are also environmental benefits of fluorescent lights,
too. A single, 20-watt compact fluorescent lamp that is used in
place of a 75-watt incandescent will save you about 550
kilowatt-hours over its lifetime. So, if your electricity is
produced in a coal-fired plant, much like many areas are, that
savings represents nearly 500 pounds of coal that doesn't have
to be burned. That means that 1,300 pound of carbon dioxide and
20 pounds of sulfur dioxide will not be emitted into the
atmosphere.
