Nicholi Tesla, not Edison, created the .
The first bulbs used charged filaments and are called incandescent.
They operate on A/C power. They consume a great deal of power and if
broke pose a significant hazard. Tesla threw out this bulb to find a
better means to produce light. Because Tesla didn't patent this bulb
and he and Edison were rivals, Editon took the work, patented it and
claimed it as his own. Tesla would eventually create the fluorescent
light that uses charged gas (a concept taken from lightning).
Fluorescents use far less power and if broke run a minimal risk.
That is not to say however, no risk exists. As with anything that is
abused or in need of repair, dangerous side effects can occur.
Fluorescent lights strobe, or flash very fast, so quickly the human eye
normally can't see the effect. As gasses are used up, the process
slows. Once the process slows to the point of visible flickering a
significant health risk exist. The strobe effect of any light over time
will have tremendous detrimental results on the human mind and
personality. Further, lighting is often used in places lacking light.
Unless full spectrum lighting is used, the body become deprived of
critical forms of light needed to produce vitamins in the skin and
serotonin in the brain.
Sony and the USPS conducted a 5 year
long study from 1985 to 1990 and found extremely elevated occurrences
of depression, violence and suicide in areas where employees spent many
hours working under bad lighting. Schools have since been ordered to
regularly replace fluorescent lights before they show sign of failing
to prevent similar reactions in children. Women are 5 times more susceptible to the results of bad lighting then men.
Health Hazards of Fluorescent Lighting
Known effects and their likely causes
The following is a list of symptoms and
diseases known to be linked to exposure to fluorescent lighting:
Headache, eyestrain, eye irritation,
fatigue, difficulty in concentration, increased rate of ‘misjudgments’ and
accidents, malaise and irritability can be caused by noise, glare and flicker from
fluorescent lighting.
Increased stress (which may in turn lead to
heart disease) can arise from increasing the intensity of artificial light with
fluorescent tubes. It has been shown that increased use of artificial light (rather than
natural light) affects the levels of hormones in the body, particularly the hormones
associated with stress, such as cortisol.
Variation in brightness, as provided by
daylight, is necessary for the normal functioning of the body’s rhythms. The
monotonous illumination of fluorescent lighting may also add to the changes in hormone
production.
Allergic skin reactions and dermatitis can
be caused by exposure to fluorescent lights. An unknown number of people suffer from
‘cutaneous light sensitivity’ due to fluorescent lights. This means that not
only can they become allergic to fluorescent lighting but they can become more sensitive
to ordinary sunlight.
Certain long-term, mild skin diseases can
become worse if the sufferer is exposed to fluorescent light. Some medical drugs
(including some tranquilizers, antibiotics, heart drugs and diuretics) can make you
particularly sensitive to UV radiation (photosensitivity). Skin eruptions then occur even
with the small doses of UV (in the 300-320nm wavelength range) emitted by white
fluorescent lights.
Hyperactivity has been linked to the
flickering produced by fluorescent lighting. Microwave emissions from fluorescent lighting
are also suspected of contributing to these behavioral disorders. Other mild behavioral
disorders in children may be made worse by working at school under fluorescent lighting.
