WHY THINKING ABOUT LIGHTING?
" M o r e l i g h t " – as Goethe said - is our wish for you. By "more light", we mean not only the amount
(quantity, brilliance), but essentially also the quality of light. And today, quite often, this is either insufficient or
even bad.

Burning sensation in the eyes, headache, allergies, inexplicable fatigue, stress or even depressions are mostly
unpleasant concomitant phenomena of often inadequate and unbalanced lighting. Reliable scientific studies have
examined and proven this fact.

is the life-sustaining element for all humans. It has shaped us for millions of years and is perfectly balanced in its
colour spectrum and attuned to nature and all living organisms. This balance descends also on our well-being,
even if we spend less time outdoors. Surely, we feel how much our mind, body and soul yearn for light and sun
and how a sunny day can make a world of difference for our well-being.

THE ILLUMINATING IDEA
WHY IS HEALTHY LIGHT MEANINGFUL AND ESSENTIAL
INTRODUCTION
For the existence of man, nourishment, water and air alone are not
enough. Another essential element that influences our psyche and
health and is, at the same time, least perceptible to us, is light,
because man is accustomed to a life under the daylight since
millions of years. Whereas 100 years ago man spent every day of
his life up to 90% under natural sunlight, today on average it is a
mere 10%. Artificial light – above all at the place of work –
dominates our modern lifestyle. The unpleasant concomitant symptoms are familiar to us and many
investigations have affirmed it: rapidly decreasing concentration, feeling out of sorts, inexplicable
fatigue, intense feeling of stress, headache or even depression.
All the same, today while we are relatively more conscious about our nourishment and there is much
being done about the quality of air and water, we are mostly helpless against the phenomenon of
"bad light". We feel it in us how the body and soul yearn for the sun. Probably, we sense it how the
light on a sunny day lifts up our spirits. Also our body signals to us that brightness alone is not
sufficient, more important is rather the quality of the light. A comparative study of the spectrum of
the conventional artificial light with that of the sunlight gives us the explanation. Besides strong
deviations in all visible colours, colours not visible to the human eye, namely ultraviolet and
infrared, are missing in artificial light and, precisely these colours in correct doses play the decisive
role as the actual health-giving constituent of the light.
The alternative solution is hence: Viva-Lite®.

HISTORY & DEVELOPMENT
As early as the 1930s, Dr. John Ott and Prof. Dr. Fritz Hollwich conducted research on sunlight-like
light sources and carried out many experiments. Developed later in USA in order to counteract
health related problems among submarine crews and astronaut teams successfully, Healthy Light
increasingly gained recognition also at work and in homes and thereby contributed immensely to
better well-being and higher levels of performance. Since the beginning of 1980s Healthy Light is
being employed in light therapy, which meanwhile has full scientific backing.
Based on personal experience, we at Light-Office are determined to popularize and propagate Healthy
Light. This intention of ours gave rise to the product range of Viva-Lite®.
Viva-Lite® Healthy Light is manufactured under strict quality controls employing the latest
technologies. The wide range of lamps offers the ideal product for every occasion. Naturally, there
are no limits to one's personal taste and, thanks to simple handling, your surroundings can be
literally plunged into a new light: Bright white light to enhance concentration at work and for
brilliant illumination ("Full spectrum light") or warm cosy light for a relaxing atmosphere in the
morning or evening ("Natural spectrum"). Viva-Lite® has a solution ready for every situation.
VIVA-LITE® LIGHT BULB WITH THE NATURAL SPECTRUM
The unique colour characteristic of this bulb is lent by
neodymium, a rare earth element.
In combination with oxygen it filters out the artificial yellow
constituent of glowing light. Thanks to the glare-free, pleasant
and warm light of this special type bulb, your eyes do not get
tired so fast and you can attend to your work fully relaxed.
Advantages:
- Natural spectrum.

VIVA-LITE® FULL SPECTRUM HALOGEN LAMPS

VIIVA--LIITE® PRODUCT DESCRIIPTIION
For using the full spectrum halogen lamps there are ample reasons:
their colour spectrum resembles that of their sun up to 98%.
It means continuous and harmonious reproduction of colours and an
optimum shadow formation. The light distribution is absolutely uniform
and no spots and patterns as in other cold light reflectors. The
illuminated objects present an outstanding display.
Compared to a standard halogen lamp, the Viva-Lite® full spectrum
halogen lamp has 80% lesser infrared component in the beam of light which reduces heating
considerably. It is guaranteed that it has neither a "braising" nor a "bleaching" effect on the
illuminated objects.
Moreover, by means of an ingenious shielding, the so-called high degree of electrical pollution in the
case of halogen lamps, which is caused by the transformers, can be restricted to a large extent. By
using D.C. transformers amazing results can be achieved.
Advantages:
- Fits into any 12V-20W/35W/50W low-voltage – Halogen lamp (Reflector).
- Standard MR16 – socket. Also known under GU (GX) 5,3 or QRCBC 50/51.
- Experience colours true to nature. The best colour reproduction you have ever experienced.
- Soothing to the eyes, improves your performance.
- Best suited for illuminating images/objects directly.
- Excellent in infrared as well as ultra-violet range.
- Superb continuous and balanced spectrum.

VIIVA--LIITE® RANGE OF APPLIICATIIONS & TARGET GROUPS..
RANGE OF APPLICATIONS
IN FACT VIVA-LITE® MUST BE THERE IN EVERY ROOM. BUT IN SOME ROOMS MORE SO!
ASPECT OF "COLOUR FIDELITY":
Target groups/Keywords: Illumination of displays at jewellers, display of crystal-ware, graphics,
paintings, textiles, flower arrangements, cosmetics, museums, photo studios, food stores, lobby
illumination, consultancy for colour in fashion and interior decoration enterprises and in every place
where colour fidelity of illumination is essential.
Viva-Lite® offers a sensational colour reproduction that is up to 98% similar to the colour fidelity of
natural sunlight. What is remarkable here is that on objects and materials containing fluorescent
substances the colours are reproduced true to nature – as is often the case, for example, in clothes or
in dental technology.
This is possible only with the right proportion of UV rays that are dosed correctly in Viva-Lite®. This
is the reason why Viva-Lite® is so popular, for example, among dentists or in boutiques. Who would
want to see that the colour selection of the own fabricated denture after all does not match 100%
with the natural teeth?
And also when shopping it is certainly more practical not having to go out of the shop into daylight
to examine each garment – just to be able to convince oneself about the actual colour of a pullover or
a trouser that may appear interesting.
Through skillful lighting arrangement with Viva-Lite®, presentation of goods can achieve significant
turnover growth. The result is, foodstuffs will appear more fresh or paintings shine more (after all,
mostly, they would have painted under natural sunlight!), flowers and plants grow rapidly and are
less susceptible to pests, jewelry items appear more expensive and high class, as they glitter and
sparkle more than before.
These are just a few examples where presentation of articles can be a catalyst to customers'
clinching decision for a purchase. Not to forget is the rewarding atmosphere that can be created
through Viva-Lite®. Naturally, this too contributes unknowingly to an optimum presentation of
goods and the best incentive to customers' purchases.

VIIVA--LIITE® RANGE OF APPLIICATIIONS & TARGET GROUPS..
ASPECT OF "HEALTH":
Target groups/Keywords: Health care, light-therapy, better vision, counteractive to headaches,
fatigue, stress, increased ability in learning and performance, medical clinics, special dental clinics,
hospitals, kindergartens, schools, colleges, universities, institutions for the handicapped and all
other public and private buildings.
Viva-Lite® takes up the health related benefits of sunshine optimally. The Viva-Lite® spectrum
simply switches on good cheer and thus creates an ideal ambience in companies, offices and in
homes for work & living. We enjoy working a little more than usual and become more productive and
more creative.
Lack of concentration due to ill-lit rooms can always be counterbalanced! And Viva-Lite® can keep
eyestrain, headache and fatigue at bay by minimizing the otherwise adverse effects of light and
electro-magnetic pollution. In this regard, mostly ballast devices, D.C and shielded cables or electrobiological
installations are the culprits. Stress, aggressiveness, hyperactivity and difficulty in
learning are not uncommon due to flickering and bad lighting, which triggers off a permanent stress
in the humans who then are often diagnosed wrongly. They can be treated properly only if the
causative factors for such attacks are identified and eliminated. – Simply changing the lamp may be
the right solution!
ASPECT OF "ECONOMY":
Target groups/Keywords: Large-scale enterprises, small and medium sized firms, social institutions,
health insurance companies, business houses, and political and environmental organisations.
The initial investment for the acquisition or re-equipment with Viva-Lite® healthy lighting system
may seem rather expensive at first. That is not so, if we consider the long-term benefits which would
be enhanced productivity, decreased absenteeism due to illness and errors due to lack of
concentration and an improved motivation for the employees - in short a direct influence over
"economic efficiency".
And then there are the statistics. The Viva-Lite® full spectrum energy-saving bulbs (spiral bulbs)
have, for example, an extraordinarily long lifespan (minimum 8000 hours) and are extremely low on
power consumption – and that with a such a light output that is worth presentable (a 23 Watt bulb,
for instance, has the same performance as two commonly available 60 Watt bulbs!). The same applies
to Viva-Lite® full spectrum tube lights. If these are used in combination with the so-called electronic
ballasts, besides mere savings on power of about 1/3 one can expect even a longer lifespan for the
tubes – mostly double the normal lifespan, in other words, onetime less for change of tubes.

LIIGHT IIS LIIFE -- OUR LIIFE IIS PRIIMARIILY GOVERNED BY LIIGHT..
Wherever natural light is absent or inadequate, man tries to create a relatively well-lit
ambience through artificial lighting. What is decisive for the right effect is, however,
its quality.
Thanks to the technological development, especially aimed at such areas of usage, our
Viva-Lite® full spectrum lamps provide near natural lighting for artificial illumination.
Numerous statements and publications confirm this supported by investigations and
reports of positive experience affirm this, as the following selection shows:
"In recent times, we have become aware that
we breathe always polluted air, eat junk food
and drink unclean water, but we seem to have
overlooked the most obvious nutrient,
namely, the light."

Piper-Verlag, Munich, 1996
"We have at last realised that light is a
foodstuff like normal food and, just as
unbalanced diet makes us ill, wrong lighting
can also make us ill and only correct lighting
can preserve our health. Research in this field
has made significant strides, but there is still
a lot to do."

Stress due to incorrect illumination.
Knaur-Verlag, Munich, 1989
"When we talk of health, balanced lifestyle
and physiological regulation, we primarily
mean the health-preserving factors in the
body, namely the nervous system and the
endocrine system. These important control
centres of the body are stimulated and
regulated directly by light, and this to such
an extent that goes beyond what the modern
science was willing to realise till recently."
J. Liberman: The Healing Power of Light –
The Influence of Light on our Psyche and Body.
Piper-Verlag, Munich, 1996
"Stress due to light is the sum of many a
dysregulation of the nervous system, such as
irritability, depending on the type aggression or
melancholy, lethargy or lack of interest. The American
space authority NASA drew consequences of these
experiences. Towards end of the 1960s it initiated the
development of full spectrum lamp, in which the
spectrum has been improved in some important
aspects as against the conventional fluorescent lamps:
the colour of the light corresponds to that of sunlight
and the radiation is distributed uniformly over the
entire spectrum. The astronauts were able to adjust to
this comfortably and, also normal users spoke about
improved attention and lively disposition."
Johannes Holler: The New Brain.
Junfermann´sche Verlagsbuchhandlung, Paderborn, 1996
"Numerous medical investigations have revealed that
for a number of body functions human beings too
depend on a minimum UV light radiation."

Rabenverlag, Munich, 1989
"The type of unnatural lighting has influence on the
depressive behaviour of school-going children during the
winter months (mood changes, lack of energy, increased
appetite, irritability, increased feeling of apprehension as
expression of season related emotional disorders - known as
Seasonal Affective Disorder, SAD or winter depression),
which affects their motivation to learn. Under full spectrum
lighting, depressive symptoms among pupils showed
significant regression as against under lighting with cold
white fluorescent light."

Waiden University, 1998
"In America, even full spectrum light is registered as a
medicinal product and is used in many therapies like
treatment of winter depression, jaundice in newborn infants,
insomnia, skin diseases and so on.
In Germany too during the recent years many health-care
centres, hotels, enterprises and homes have switched over to
near natural, health-promoting and energy-saving lighting
systems."
E. Brandmayer, B. Köhler: Light bestows Life.

A SELECTION OF ARTICLES ON THE EFFECTS OF HEALTHY LIGHT
HEALTHY LIGHT - RESEARCH WORK BY JOHN OTT*
When we are concerned about the quality of light and the importance of light for the well-being of all
living organisms, above all we must mention the pioneering research work by Dr. John Ott. His
pioneering work on the effect of various sources of light on plants, animals and humans may be
considered as one of the most important discoveries of last/this century.
On the quick-motion film shots** done on an assignment by Walt Disney Dr. Ott observed that the
germinating pumpkin seeds under fluorescent light did not grow fully, whereas they grew
remarkably when ultra-violet light was supplemented to the source of light. During investigations in
the 1950s and 60s he measured the life expectancy of animals in the laboratory, which were kept
under different forms of fluorescent light, as against animals that lived in natural, unfiltered
daylight. Such experiments were conducted simultaneously in several renowned medical institutions
and research clinics. Without exception, dramatic differences were observed in the life expectancy of
the laboratory animals.
For example, mice kept under light from pink coloured or daylight-like white fluorescent tube lights,
survived on average for 7.5 to 8.2 months. On the other hand, their cousins, allowed to live under
natural, unfiltered light, were astonishingly healthier and lived on average for 16.1 months.
Based on the results of these studies and other experiments, Dr. Ott concluded that natural light is
as essential for the life and health of animals as it is for plants. Consequently, he recommended
designing of a modified fluorescent tube light that came closer to the full spectrum of natural
sunlight. According to Dr. Ott's ideas this should be done by adding a phosphor compound that was
capable of producing three types of ultra-violet radiation at almost the same ratio as is the case with
sunlight. Dr. John Ott was the driving force behind the development of the so-called full spectrum
fluorescent tube lights.

THE EFFECT OF HEALTHY LIGHT ON HUMANS*
Now Dr. Ott studied further the adverse effects of incorrect lighting on human health and
performance. In 1973 he conducted, in collaboration with the Environmental Health and Light
Research Institute in Sarasota/Florida, an investigation in four classrooms for first grade pupils. None
of the four class rooms had any windows and in two of these rooms full spectrum fluorescent lamps
provided with special protective devices against radiation were installed and in the other two rooms
normal cool white fluorescent tubes. Thereafter, using hidden quick-motion cameras*** the pupils
and teachers were filmed in random sequences. The photographic documentation was unambiguous:
Under the cool while lighting, the pupils showed symptoms of hyperactivity, exhaustion, irritability
and inattentiveness. In the classrooms with full spectrum lighting, on the other hand, considerable
improvement was noticeable in regard to behaviour, participation and academic performance within
a month after installation of lighting systems. Moreover, thanks to full spectrum lighting some
children with learning disorders and extreme hyperactivity became perceptibly calm and overcame
to some extent their difficulties in reading and learning.
In children working in rooms equipped with full spectrum lighting system, the incidence of dental
caries one-third lesser than in children, who were learning in rooms with normal fluorescent light. In
regard to frequency of dental caries, l. M. Sharon, R P. Feiler and S. W. Burney arrived at the same
results. These results were not surprising, because even during the 1930s observations were made
on a large group of children that dental caries occurred more frequently during the school days (that
is, during autumn, winter and spring seasons) than during the summer vacation months. Also there
appeared to be a direct relationship between incidence of caries and sunlight radiation in the
relevant geographical region where the children were living. The more you have of sun the lesser
caries to worry about.
FULL SPECTRUM LIGHT AND CHOLESTEROL LEVELS*
Recently, the poultry industry became aware of the advantages on chicken breeding maintained
under full spectrum lighting. Initial results indicated that chickens that were growing under full
spectrum lighting, developed much better than their cousins bred under other artificial lighting.
They live twice as long, lay more eggs, are less aggressive and, their eggs contain approx. 25% less
cholesterol. The fact that the eggs of chickens living under full spectrum light contain less
cholesterol need not surprise us if we consider that also in humans the cholesterol levels decrease
under the influence of sunlight.
Perhaps even our cholesterol levels would be lower and our general health better if we spent more
time in vacation and used full spectrum lighting indoors. Today we know that a moderate exposure
to sun rays decrease the cholesterol levels rapidly and significantly. The importance of this
information becomes evident if we consider the fact that nearly 50% of all deaths in some countries
are due to cardiac and circulatory diseases which, as generally known, are linked in many cases to
high cholesterol levels.

SURVEYS,, IINVESTIIGATIIONS & FURTHER DOCUMENT RESOURCES
LIGHT AND HUMAN PERFORMANCE*
The most extensive investigation on the effects of light on the function and development of the
human organism was perhaps the pioneering work by Dr. Darell Boyd Hannon within the framework
of the project "The Coordinated Classroom" (ca. 1938). The objective of this project was to protect
and promote awareness for health among school-going children.
What was investigated?
The first step in the investigation was to obtain a complete overview on the various physical and/or
psychic disorders that the examined children were suffering from. During the first three years, more
than 160,000 school children were monitored for health disorders and school related problems and
the room conditions in more than 4000 classrooms were examined.
Outcome:
The outcome was that more than half the number of children were suffering on average from two
identifiable nevertheless avoidable deficiencies at the end of primary school. When this was
correlated with the factors of environs, it became evident that many problems were connected with
certain body functions, which are influenced by incidence of light into eyes.
In the background of these findings, in 1942 further intensive research work was initiated. In 1946,
on the basis of all collected data, plans were initiated to establish a technically excellently equipped
research centre where it was to be investigated as to which type of lighting, sitting posture and
colour layout were prerequisites for maximum academic performance at minimum effort. On
completion of preliminary work, one of the investigated schools was redesigned accordingly and a
six-month test was conducted.
Select health related complaints were evaluated - once at the beginning of the investigation and then
at the end of six months. The outcome showed a remarkable regression in several typical problem
areas:
Problem areas Degree of regression
Vision impairment 65 %
Nutritional disorders 47.8 %
Chronic contagious diseases 43.3 %
Posture disorders 25.6 %
Chronic exhaustion 55.6 %
Besides these indications of obvious improvement in physical well-being, comparable results were
observed in respect to the academic performance, although no attempt was made to modify the
curriculum or the teaching methodology. Dr. Hannon's study is extremely significant, since it is
concerned with the mostly overlooked organic needs of children in the learning stage. The
investigation proved undoubtedly a correlation between the school environs, health and ability to
learn.

PRESS RELEASE "COMPANY PROFIILE"..
PROS FOR WELLNESS & HEALTH
HOW A BUSINESS IDEA EMERGED FROM THE ELEMENTS OF LIGHT, WATER AND SOUND
Winterbach, November 1999. After reading the book "Light – Medicine Of The Future" by Jakob
Libermann, Tobias Rückert, the managing director of Light Office, did not put it away on the shelf.
Soon he hit upon the groundbreaking idea of developing future healing methods using light energy
into a business proposition. Since the founding of Light-Office in 1999, he has been developing and
distributing products that utilise the medicinal effect of light.
Light-Office develops select items for the market segments of preventive health-care, sports, fitness,
beauty, personal care and relaxation which round up the package for well-being.
But Light-Office is also actively engaged in the field of research on light and colour therapies and on
the subjects of wellness and health. Its core activity in this respect is to investigate the correlation
between the elements of water, light, sound and the physical well-being of humans. The research
work is conducted in cooperation with institutions, academies and experts and it serves as the basis
for the selection and development of different products through distribution networks.
Tobias Rückert, an expert in the field of wellness and health products sourced from all over the
world, says: "For us it is extremely important to throw light on various areas and elements such as
light, sound and water from a scientific perspective. We are quite open to new directions of research
and development subject to critical examination. We use the latest findings from the research
organisations to develop new products."
Customer service and ecological concerns at the forefront
Reasonable pricing at the best possible quality are the top-most priority for Light-Office, because,
after all, for a long-term cooperation pricing, quality and service mean enduring success to the
customer as well as to the supplier equally. In the distribution of products, ecological concerns are
given due regard from the point of production till marketing.
Tobias Rückert: "To ensure top quality of our Products & Services, we deploy our entire know-how.
Innovations and flexibility help us achieve these objectives. For this purpose, we welcome
collaborations and partnerships."
Success through partnerships
To take advantage of the synergetic potential, Light-Office is continuously in search of new
collaborations and Joint Ventures, including affiliate programmes and Franchise Partnerships. For
such collaborations, the spotlight will be on enterprises already engaged in the business-line of
Wellness, Beauty and Body care. Over and above this, cooperation with research institutions and
experts and interested lay people will be sought. Tobias Rückert has great expectations: "The aim of
this synergetic endeavours should be to provide the latest information, products and trends to the
customer."
