How does procognitive lighting differ from conventional full-spectrum LED lighting?

Spectrasol procognitive LED lighting vs. other full-spectrum LED lighting: Main differences

The main difference between Spectrasol and other full-spectrum LED light sources consists in the targeted focus of conventional full-spectrum LEDs only on the cyan melanopic or circadian energy, which, among other things, benefits the cognitive functions and overall vitality of the user. However, the spectral composition of those luminaires tends to be incomplete overall, or they suffer from divergences from natural sunlight that can be harmful to the organism. Since much is still unknown about the non-visual effects of light, artificial lighting should mimic, as much as possible, natural sunlight, which has always been and will always be the best source of light to which organisms have adapted during evolution. This is the only way to ensure all the positive effects while avoiding the undesirable ones.

Key differences:

(1) Spectral composition (SPD):

• Spectrasol procognitive lighting:
  • Optimal proportion of the cyan region of the spectral composition (460-500 nm): Stimulates cognitive functions – concentration, memory and learning.
  • All wavelengths in optimised proportion following the pattern of the sun – 97% match
• Conventional full spectrum LED lighting:
  • The spectrum may vary depending on the manufacturer: It is not always balanced and can diverge significantly from natural sunlight
  • It may contain excess blue light: It may damage the retina of the eye in the event of prolonged use
  • It will not contain red long wavelengths and this may not be subjectively pleasing to the user

(2) Benefits:

• Spectrasol procognitive lighting:
  • Very pleasant light in terms of sensation
  • Increased cognitive performance, concentration, memory and productivity
  • Mood improvement, stress reduction
  • Promoting healthy sleep and vitality
  • Strengthening the immune system
  • Protecting the retina from harmful blue light and regenerating the eye in real time
• Conventional full spectrum LED lighting:
  • More even spectrum than conventional LEDs: If it contains cyan energy, it supports circadian rhythms and the resulting benefits for the organism.
  • It may not be beneficial to users’ eyes (high content of harmful blue light)
  • It may have too cold a tonality that will not be comfortable for the user

(3) Applications:

• Procognitive lighting:
  • Work areas: Promoting productivity, health and mood.
  • Schools and educational institutions: Improved learning, concentration, health and mood of students and teachers.
  • Hospitals and sanitary facilities: Supporting the recovery, mood and vitality of patients and patients in recovery.
• Conventional full spectrum LED lighting:
  • Wide range of applications: corridors, waiting rooms, dining rooms, meeting rooms, etc. – where users are not present for a long time
