Full Spectrum Light
Simulated full spectrum light is color-corrected light that operates in the
range of 400 to 800 nanometers. This light will simulate the optical brilliance
of outdoor light at noontime. This light can be measured by two numbers, CRI
(Color Rendering Index) and Kelvin Temperature or (Degrees Kelvin). The secret
to full spectrum light and optically balanced light is how close you can get
to the optics of natural light. The Sun at noon has a natural color temp of
100 CRI and between 5000 and 5500 degrees Kelvin at noon time. Both CRI and
Kelvin are important for the simulation sunlight.
When you simulate light that matches the optical brilliance of sunlight, the
pupils in the eyes will become smaller. This response generates clearer vision
and higher perception. The results are lower glare and eye fatigue. When you
can combine Lux intensity with high CRI and balanced Kelvin tempurature, you
will have full spectrum light that not only matches the optical brilliance
of the sun, but reduces levels of melatonin and the stress hormone, cortisol.
This light is not "daylight" color. It is clear, brilliant, white light and simulates the exact color of sunlight at noon. The one fact that proves that this is true is asking ourselves; What is the one thing in our life that is missing? We spend so much time indoors, not only in the winter when the days are shorter, but when we work all the time. Sunlight is what we are missing and light that simulates those brilliant life giving wave lengths will be much more effective in treating seasonal depression than any other source or color of light.
What separates our full spectrum light from the rest are color temperature
ratings. It is also important to note that with light therapy, intensity is
also important. The facts are simple, we offer the highest optical performance
of any light therapy unit on the market today, while still delivering the highest
Lux output. No light performs better than UltraLux in all three categories.
Ultralux II produces the highest lux output per square inch of any light made
and we do this while maintaining an average CRI of 90 and a Kelvin tempurature
of 5000 Kelvin. You will see many companies state that they use full spectrum
lights, but you will not see the numbers in print or graphs below to prove
they use full spectrum lights.
NOTES ABOUT UV:
All UltraLuxâ„¢ products use "NON UV" full spectrum bulbs. You do
not need UV for light therapy. Many companies that only manufacture light therapy
devices tell you that all full spectrum fluorescent lights produce UV. This
is not a true statement. We are lighting experts and we manufacture eight different
lines of full spectrum light products. We also manufacture full spectrum
UV lamps for the reptile industry. These lamps require special UV phosphors
to produce any measurable amounts of UV. We do not put these phosphors in any
of our light therapy products.
Below are Spectral Emission Distribution charts. These charts visually show you the colors you will see with each lighting type. As you can see, the light is balanced in blue, green, yellow and red.
