The importance of full spectrum light for authentic colors
Full spectrum in a nutshell:
Over the last two decades, LEDs have revolutionized the market for lighting technologies thanks to their energy efficiency.
With continuous improvements in technology and materials, there is growing interest in intelligent lighting solutions, especially in optimizing the light quality of LED illuminants. The introduction of full spectrum LEDs aims to match the color rendering of natural sunlight, achieving an authentic color perception. This is particularly important for sectors such as retail, hospitality, medical facilities and design studios, where precise and lifelike lighting is required to present products or services in the best possible way.
Approach to sunlight
The triumphal procession of LEDs has been continuing for almost 20 years. With their convincing energy and cost efficiency, LEDs have displaced almost all traditional lighting technologies from the market. The LED technology and the materials used are constantly improving, the demands on smart lighting solutions are increasing daily! The focus is increasingly shifting to improving and optimizing the light quality of LED illuminants, luminaires, and lamps, which are integrated into intelligent and holistic lighting solutions. The term full spectrum refers to the approximation of the color rendering of LEDs to that of natural sunlight.
Authentic colour perception
he new full spectrum LEDs have almost identical color spectra to natural sunlight. In contrast to conventional LEDs, the color spectrum of the new full-spectrum light sources does not contain a peak in the blue color range typical for LEDs.

Over the last 20 years, LEDs have revolutionized the lighting industry with their efficiency, while the technology continues to improve to meet increasing demands for light quality. Particularly interesting is the development of full spectrum LEDs, which offer authentic color rendering and mimic natural sunlight.

Definition Colour Rendering Index
The colour rendering index is expressed in Ra or CRI (Colour Rendering Index).
The Ra or CRI value evaluates the quality of the colour rendering of a light source.
The higher the value, the better the colour rendering.
he colour rendering index refers exclusively to the visible range of the colour spectrum of light (wavelength range from 380 to 780 nm).
CRI 100 = light spectrum of the sun
Das natürliche Sonnenlicht enthält alle Lichtf arben, die in ihrer visuellen Helligkeit gleichmäßig über das Farbspektrum verteilt sind.
Der CRI-Wert von 100 entspricht dem Farbspektrum von natürlichem Sonnenlicht auf der Erdoberfläche.

CRI>80 means that the color rendering of the measured illuminant corresponds to at least 80% of the color rendering in sunlight.
CALCULATION OF THE CRI VALUE (RA)
The test colors (see figure) are standardized and were defined with a remission curve (non-directional reflection of waves) in DIN 6169. The average value of the first 8 test colors is used to calculate the CRI value (Ra).
All other colors from R9 upwards are reference colors (Re), which are used in detail for the specific evaluation of a color if required. .
A high color rendering index does not automatically mean that all colors are equally well rendered and therefore cannot be assessed equally well.
The color rendering value of each individual light color can be read in the test report of the light laboratory. With full-spectrum LEDs, it is noticeable that the R9 value, for example, is also very high (with conventional LEDs very often well below 50).
This means that the red of an illuminated object is perceived as very rich and particularly powerful.
For almost two decades, LEDs have been shaping the lighting landscape with their efficiency and have almost replaced traditional technologies. The constant further development of LED technology and materials ensures that the requirements for intelligent lighting solutions are met, with a particular focus on bringing the color rendering of LEDs closer to natural sunlight.

FULL SPECTRUM LEDS - AUTHENTIC COLOUR PERCEPTION FOR ALL AREAS
Red should stay red! Illumination with a low CRI value does NOT allow an authentic color perception as it is in natural sunlight (daylight). zu.
- Especially when it comes to making specific decisions about the colors of objects (e.g., in dental surgeries when choosing the color for the filling, etc.)
- when you want to present sales items in an attractive way for the customer with natural-looking colors (e.g., fashion, food, etc.)

Questions & Answers About Full-Spectrum Light
ISOLED offers full-spectrum LEDs that almost perfectly mimic natural sunlight. Unlike conventional LEDs, which often have a peak in the blue color range, our full-spectrum LEDs have a balanced spectrum without such peaks. This results in authentic color perception, which is particularly important in areas such as retail, gastronomy, medical facilities, and design studios.
The CRI, also known as the Ra value, measures a light source’s ability to reproduce colors compared to natural sunlight. A CRI value of 100 corresponds to the spectrum of natural sunlight. ISOLED offers full-spectrum LEDs with a CRI of over 99, ensuring almost perfect color rendering. This is essential for applications where color accuracy and fidelity are of the highest importance.
ISOLED full-spectrum LEDs are ideal for professional applications where color accuracy and fidelity are crucial, including:
Retail: Optimal presentation of products through authentic color rendering.
Gastronomy: Creating a pleasant atmosphere with natural light.
Medical facilities: Important distinction of skin tones and other colors.
Design studios: Precise color perception for creative work.
In these areas, high color rendering quality enhances customer perception and satisfaction, as well as the precision of professional work.
Conventional LEDs often have a peak in the blue color range, which can lead to distorted color perception. ISOLED full-spectrum LEDs, however, have a balanced spectrum without such peaks. This allows for authentic color perception very close to natural sunlight. Another advantage is the high energy efficiency of our LEDs, while maintaining excellent color rendering quality.
