All life on our planet has adapted
to and is nourished by light from the sun and sky, a critical balance of visible
color and invisible ultraviolet wavelengths. Over the ages, virtually every
living thing developed with the help of Nature's Full Spectrum. Today most people
don't get enough sunlight because they spend so much time indoors, and most lack
the understanding of lighting and that there is significant difference is type,
and quality of lighting available. Most lighting in homes, schools, offices, factories,
stores, is so bad that many health disorders can be traced to the lack of natural
lighting. Natural sunlight and various forms of light therapy can help reestablish
the body's natural rhythm (circadian rhythm - the body's inner clock) which controls
timing of sleep, hormone production, body temperature, and other biological functions.
Disturbances in this rhythm can lead to health problems such as depression (SAD
- Seasonal Affective Disorder) and sleep disorders. Light therapy and the use
of natural full spectrum lighting are becoming an integral treatment for many
related health conditions. How
Light Therapy Works - As light enters the eyes, millions of light and color
sensitive cells called photoreceptors convert the light into electrical impulses.
These impulses travel along the optic nerve to the brain where they tripper the
hypothalamus gland to send chemical messengers called neurotransmitters to regulate
the automatic functions of body. The hypothalamus is part of the endocrine system
whose secretions govern most bodily functions - blood pressure, body temperature,
breathing, digestion, sexual function, moods, immune system, aging process, and
circadian rhythm. Full spectrum lighting (containing all wavelengths) sparks the
delicate impulses that regulate these functions and maintain health. The
Importance of Natural Sunlight - According to numerous studies, poor light
poses a serious threat to health. Many firmly believe that the best light for
maintaining health must contain the full wavelength spectrum found in natural
sunlight. Most artificial (incandescent and standard fluorescent) lighting lacks
the complete balanced spectrum of sunlight. The lack of the full spectrum interferes
with the body's optimal absorption of nutrients, a condition known as "malillumination".
Windows, windshields, eyeglasses, smog, and suntan lotions all filter out parts
of the light spectrum and contribute to the problem. Most offices, even those
with uncovered windows and the lights on, have a light level of only 500 lux (the
international unit illumination) as compared to outdoor light, which has about
50,000 lux, or about 100 times more. Light levels for night shift workers are
usually about 50 lux. We spend about 90% of our lives indoors, under inadequate
lighting conditions, which can cause or worsen a range of health problems, including
depression, heart disease, hypertension, depression, insomnia, premenstrual syndrome,
migraines, and carbohydrate cravings, associated with metabolic imbalances. A
ten-year epidemiological study conducted at Johns Hopkins University Medical School
in Baltimore, Maryland, showed that exposure to full spectrum light (including
the ultraviolet frequency) is positively) related to the prevention of breast,
colon, and rectal cancers. In Russia, a full spectrum lighting system was installed
in factories where colds and sore throats had become commonplace among workers.
This lowered
the bacterial contamination of the air by 40 to 70 percent. Workers
who did not receive the full spectrum light were absent twice as many days as
those who did. Recent tests in classrooms, two using standard fluorescent lighting
and
two using full spectrum lights, indicated conclusively that students exposed to
the full spectrum lighting had a marked diminishment of hyperactivity, less absenteeism,
and higher academic achievement. SAD
(Seasonal Affective Disorder): Full spectrum light and bright light are effective
treatments for Seasonal Affective Disorder (SAD). The symptoms of SAD are depression,
excess sleeping and eating, withdrawn feeling, lowered sex drive, etc. Melatonin
levels are found to be very high in-patients with SAD. Daily exposure to sunlight
or full spectrum light has been known to eliminate SAD symptoms. UV
or Not to UV: That is the question: The term "ultraviolet" causes
most people to think of harmful rays, cancer, cataracts, aging, and wrinkles.
From sunglasses to suntan lotion, most of the UV is blocked or filtered out.
Blocking
all of the UV rays may severely weaken the body's defenses. There are strong indications
that UV light through the eyes stimulates the immune system. Moderation is the
key. There is no question that large amounts of UV
are harmful, however, in
trace amounts, it is very beneficial. Sunlight contains large amounts of UV in
various wavelengths. Each wavelength is responsible for various things, such as
tanning response in humans, activate
synthesis of Vitamin D, and absorption
of calcium and other minerals. Sun therapy was very popular in Europe at the turn
of the century, and until the late 1930's. It was known as heliotherapy, named
after the Greek God of the
sun - Helios. By mid 1930's, sunbathing and UV therapy
was most effective treatments for many infectious diseases such as: lupus, eczema,
acne, herpes, rheumatoid arthritis, gout, cystics, anemia, colitis, kidney problems,
etc. Then in 1938, penicillin was discovered, and world turned to pharmaceuticals,
and drugs became big business. Sun therapy was then regarded as medical quackery.
There is another side to the healing with light - and most do not know the tremendous
health benefits from UV. UV light activates the synthesis of Vitamin D, which
is a prerequisite for
absorption of calcium and other minerals. UV light can
lower blood pressure; can increase efficiency of the heart, can improve EKG readings
and blood profiles; can reduce cholesterol; can increase the level of sex hormones
(Vita-Lite
has a balanced UV, and is used extensively for enhancing the mating and reproduction
of indoor pet and animals); UV activates an important skin hormone - solitrol
(works with Melatonin to generate changes in mood, circadian rhythms, and seasonal
reproduction.). There hundreds
of medical studies completed on the health benefits of ultraviolet light, however,
prevailing medical establishments continue to maintain that UV is dangerous to
our health. It is agreed that too much UV is harmful, however, a basic amount
is needed to support life and the immune system, just like any other vital nutrient.
Today we spend most of our time indoors, and under artificial lighting. Most indoors
lighting (homes, offices, and factories) has inadequate brightness and lacks the
spectral components of sunlight. Additionally, most light bulbs give off a gross
distortion
of the visible light spectrum, emitting strong peaks of light energy in the yellow,
red and infrared portions of the spectrum. That is why most lighting in homes
and offices, etc. looks yellowish and dingy. Natural
Full Spectrum fluorescent lighting simulates full color and ultraviolet spectrum
of sunlight, and reveals detail and color accurately. It is a beautiful all-purpose
white light - a pleasing fluorescent tube that operates in existing fixtures for
complete lighting of offices, stores, factories, schools, hospitals, banks, or
wherever fluorescent light is used. Natural
Full Spectrum Fluorescent lights have the proven capability to: Blend with natural
light from windows and skylights; Reveal detail and colors accurately. Improve
seeability; Help improve the performance and productivity of people; Excellent
for Pet and Plant lighting. Simulation of natural light means that environments
lit with natural full spectrum fluorescent light bulbs can blend perfectly with
the natural light from windows and skylights. The eye does not have to adapt to
a new spectrum, color temperature or color rendition when one goes from outdoors
or a naturally lighted environment to an indoor environment lighted with Vita-Lite.
Interior colors are true and details are rendered accurately. Natural light energizes
the environment for people. They generally feel better, are more alert, see better
and perform better. In a survey conducted to determine the impact of full spectrum
lighting in the workplace it was
found that: People felt more relaxed and less
fatigued with full spectrum lighting than Cool White, with higher eye comfort;
The subjects perceived full spectrum lighting as significantly more pleasant,
natural, bright and stimulating; Additionally, they rated their seeing tasks as
more distinct under full spectrum lighting, and their work tasks as easier and
more satisfying. Not all
"Full Spectrum" light bulbs are true Full Spectrum - noon daylight bulbs.
Light bulbs are rated by 1) Lumen Output; CRI (Color Rendering Index); and Color
Temperature (Kelvin Degrees). These ratings are required to determine the type
of light the bulb is emitting. Natural light has a unique spectrum, which includes
a balance of UV and visible color regions. This spectrum balance of UV and Visible
light is necessary for lamps to be called "Full Spectrum". Therefore,
if the spectrum from light bulbs closely matches this balanced spectrum of natural
noon-day light, such bulbs can accurately and legitimately be described as Full
Spectrum. Otherwise, the output of bulbs that does not meet this definition cannot
and should not be described as Full Spectrum. Most so-called "Full Spectrum"
incandescent bulbs and neodymium) are not true "Full Spectrum" and do
not match high quality full spectrum fluorescent light bulbs. Spectral
output analysis clearly shows that these types of bulbs do not meet Full Spectrum
requirements. These type bulbs have a rare earth element (neodymium) in the glass
that reduces the amount of yellow energy from an
incandescent filament, thus
producing a unique color-rendering lamp. Several of the so-called "Full Spectrum"
incandescent manufacturers do not list ratings for Color Temperature, CRI, Lumens,
on their "Full Spectrum"
incandescent bulbs. Most incandescent and
other "Full Spectrum" bulbs have various color tones (pink, purple,
etc.). Our products are the highest quality true full spectrum products available.
All our products are rated with a Color Temp. (K), (CRI), and Lumen Output varies,
depending on bulb. There is no guessing to the Lumen Level, CRI, and Color Temperature
(K). Furthermore, the spectral analysis closely matches noonday sunlight and a
balanced UV, which incandescent bulbs do not have.
