NASLI - a more natual light in your space.

Look behind the scenes...

The full spectrum NASLI light has following properties:

Colour Rendering Index Ra = 91–100 colours like in a daylight
Chromatic Temperature Tc = 5500–6500 K daylight white light similar to noon light
Circadian Action Index Ac = 85–115 similar effect on the brain as sunlight

There properties are a short answer to an extensive research.

  • Prof. Fritz Hollwich found that fluorescent tubes with poor colour rendering can raise the stress hormone levels. This is why our sources of light have color rendering of 1A.
  • Dr. John Ott observed that plants grow better and people are more calm and more alert under artificial light of a cold tone. That's why our light sources have cold daylight tone similar to noon light.
  • Ir. Van den Beld, Russell G. Foster, PhD, J. Gooley, PhD et al. discovered that the photosensitive retinal ganglion cells (ipRGC), which control also sleep hormone melatonin level, are most sensitive to blue light. So this is why our light sources have a high share of blue that shortens morning waking up and keeps people active and alert.
