CRI – or Color Rendering Index – is one of those technical terms that you often read but rarely truly understand. Yet, CRI plays a crucial role when it comes to the quality of light – be it in the living room, the office, or a retail store.
In this article, we explain simply and practically what CRI means, why it's important – and what you should look for when buying lights.
What is the CRI value?
CRI stands for Color Rendering Index. It indicates how natural colors appear under an artificial light source – compared to sunlight.
The CRI is given on a scale from 0 to 100:
-
100 = perfect color rendering, like sunlight
-
80–89 = good color rendering, suitable for living areas
-
90+ = very good color rendering, ideal for demanding applications (e.g., cosmetics, art, textiles)
Why is a high CRI important?
A high CRI ensures that colors:
-
appear truer, more vibrant, and with greater contrast
-
do not look "washed out" or "grayish"
-
are more easily distinguishable from each other
Examples:
-
In the bathroom: Makeup looks significantly more realistic with CRI 95 than with CRI 80.
-
In the living room: Wall color and furniture appear more harmonious because the light causes no color distortion.
-
In the office or retail store: Products and documents appear clearer – which looks professional.
How can you identify the CRI value?
Many high-quality luminaire manufacturers specify the CRI on the packaging or in the technical data. It can also be referred to as "Ra" – for example:
🡪 CRI ≥ 90 or Ra ≥ 90
If color rendering is important to you, look for luminaires with:
-
at least CRI 80 for normal living areas
-
CRI 90 or more for bathrooms, kitchens, workplaces, shops, or showrooms
Typical CRI values in comparison
| Light Source | Typical CRI |
|---|---|
| Sunlight | 100 |
| Incandescent bulb | 95–100 |
| LED (Standard) | 80–85 |
| LED (Premium) | 90–98 |
| Fluorescent tube | 60–80 |
| Energy-saving lamp | 70–85 |

Frequently Asked Questions (FAQ)
What's better – CRI 80 or 90?
CRI 90 provides significantly more realistic colors and is ideal for all living and working areas where details are important. CRI 80 is okay, but not premium light.
Is CRI more important than lumens?
Both values are important: Lumens measure brightness, CRI measures color quality. A bright light with a poor CRI can still distort colors.
What is the CRI of LED strips?
Cheap products often only have CRI 70–80. With high-quality LED strips, you get CRI > 90 – perfect for living spaces.
Conclusion: Live more beautifully – with the right light
Not all light is equal. If you value harmonious colors, atmosphere, and quality, you should include the CRI value in your decision the next time you buy a light.
