The compact fluorescent light bulb has a shadowy side ...
...
But a plasma bright side too
Those two sides of the compact
fluorescent light bulb should NOT be
incompatible though. Moreover the shadowy side doesn't
have to be
such a disadvantage and it probably won't. (And in some places the
problem has already
been addressed.)
What? A
Compact fluorescent Light bulb is Like a Mini plasma tv?
- If it has a shape remotely like a bulb - we call it a compact fluorescent
light bulb;
- And if it is placed on a grid of a miriad tiny
clusters of three (giving off red, green or blue, when electrically
charged), we call it a
PLASMA television.
It's a fourth state of material (gas, solid, liquid being the basic
three.) When particles of the nucleus are separated into ions -
positive proton and negative electron - the distance between them is
bridged by electricity.
When the electron falls back into the nucleus
the discharge creates very intense UV light.
So yes, this whole thing into a
closed container and you get what we call plasma light.
the bright
side
where compact fluorescent light bulbs really shine
“The same
technology drives those super bright plasma televisions.
Both have been
around for dozens of years, both neglected for too long.

In
a plasma television those containers are really tiny, put on a grid
and each point on the grid is excited by electricity simultaneously.
The same thing happens in a compact fluorescent light bulb.
And that is
the bright side and a very promising at that. There are many things
stem from here including the
air purifier compact
fluorescent light that is said to ionise indoor air by
passing on electrical charge in the near proximity of a specially
designed bulb. And the rich daylight brightness had made CF bulbs
really good
candidates for
conventional light box therapy.
And further using the analogy of the color plasma television, by using
various filters compact fluorescents are theoretically possible to make
in all the colors of the rainbow as well as UV. The only
problem of course are the filters that would make the light less
efficient. In the
new
generations of LED lights (bulbs and downlights) this is
no longer the problem and that of course further increases efficiency.
Price however, for the moment is prohibitive for LEDs here unless they
are for commercial commercial applications.
That is why
for the
price
conscious, compact fluorescents should be the light fixtures of choice.
Their prices are relatively moderate
and already falling and their performance is established and reliable.
This
Guide is about LED lights. So it is fair to ask, why do I have to say
that compact fluorescent light bulbs should be in fact the light
fixtures of your first choice for many home light fixtures …
? It is a good question, and the answer is that I don't have to say
this. But you need to make an informed decision before buying.
Besides,
I do use fluorescent bulbs - Like a LOT
In fact, they
are the current choice of
the day for folks who are determined to save energy and are
very
budget conscious.
Add to this that - most recently - there
are
full spectrum fluorescent light bulbs too :o) They are developed so
that they could replicate the richness of natural daylight and combat
SAD (seasonal affective disorder.) Actually.
CF bulbs
compare relatively well with LED for effective light therapy
though the balance is heavily tilting towards the latter.
Although I really
do
think that LEDs could have an edge in quality daylight imitation
precisely because they are narrow spectrum. And that should allow
better filtration of the less needed spectrum. But that's just
my thing.
You've got to see the difference for yourself of course.
(If you are in Australia or part of the UK you’d
probably call them fluorescent globes. This might sound somewhat
embarrasing, especially if I mention that for the most part fluorescent
lights don’t have the spherical shape of a globe...mostly
they are wound up spiral pear kinda shapes.)
Actually, they come in three main shapes: tubes, spirals and
(occasionally) with a near pear-like shape. They usually come frosted
because of the high intensity light it gives off. (All I could see so
far were frosted. But then again I rarely notice things directly in
front of me.) Yeah, when I do, I make a note of it.

and the
Shadowy
side
Mercury is enviro-toxic and It could be VERY unhealthy
Without
separation, some estimate that the loss of energy in recycling nearly offsets the gain on energy using
CF bulbs.
The UV light the the plasma emits wouldn't be good for much from a
compact fluorescent light bulb unless that light excited a third
substance which in turn would emit nice visible white light. And that
substance is mercury. A very thin layer of vapour is blasted on the
inside of the glass container that is the luminaire of the fluorescent
light fixture.
But there
is a problem with that mercury. A BIG problem ...
The other downside comes from the fact that the glass is luminaire.
Because when that when glass is broken or is leaking due to occassional
manufacturing fault the
escaping
mercury could contribute to some noticeable headache. And mercury
is
HIGHLY TOXIC
even
in very small micro quantitites. Do
NOT
underestimate this!
In sufficient quantities mercury - much like pulsed radio frequency or
pulsed microwave radiation - is
brain
damaging. But mercury is particularly ugly because it can
effect chemically induced partial lobotomy (or irreversible frontal
lobe damage), according to Noble prize winning
Betrand Russell and
others.
Mercury is also very hard
and expensive to recycle. In the US and Australia, the
uptake of
Compact Fluorescent (CF) has been rapidly increasing lately. In
Australia the use of incandescents will be illegal from 2010 and the
use of CF has been very much encouraged. Some rebates are also in the
pipeline.
However, the recycling of
the Compact fluorescent light bulbs is a strain on the system, unless
properly separated from
the rest of the rubbish. In many countries, proper recycling
has not yet been implemented.
So unless proper system of recycling is in place near you, please
dispose of your used compact fluorescent light bulb with
utmost
care, and
treat it like
HAZARDOUS
WASTE, because it is. Conceal it in sealable plastic bags,
and take it to the point where you council or collects hazardous waste.
some
comparison with incandescents
and what to check when buying fluorescents,
and Then running Them in ...

In
comparison with compact fluorescent light bulbs, incandescent
bulbs contain near vacuum to enable the
thin metal filament inside (wolfram or cadmium) to burn for longer.
That red
hot burning
is essential for creating
the bright incandescent white glow - the light those globes
give off.
Questions
to ask when chosing the right CF bulb:
Energy rating,
wattage (often confusing). Is it
dimmable? - Many are, and that's a
good thing. We don't talk about it, but light pollution is also hurting
wildlife and disrupts natural habitats.
What
to check for when running it in: color of glow (warning
sign -
if different from expected return quick. It could be saying to you -
heck, I'll never burn bright.)
More often than not the choice comes down
to this: Do I choose an
incandescent
bulb or a compact fluorescent light bulb; if so do you really
compare
apples with pears? (Or more like apples with pears, spirals, tubes and
other
exoticly
shaped similarly energy efficient light bulbs.)
