1. What is CRI? Understanding CRI Parameters in LED Lighting
1.1. What is CRI?
When choosing LED lights, users often focus on wattage, color temperature, or brightness. However, there is an equally important parameter that is often overlooked: CRI (Color Rendering Index).
CRI is an index that evaluates the ability of a light source to reproduce colors compared to natural light or a standard light source. This index is measured on a scale from 0 to 100. The higher the CRI value, the more accurate and closer to the actual colors of the illuminated object will be.
For example, when illuminating a painting, a sofa, or a dish with a low CRI light, the colors may appear pale or inaccurate. Conversely, an LED light with a high CRI will make the colors more vibrant, clear, and realistic.
1.2. How is the CRI (Color Rendering Index) evaluated?
CRI is determined by comparing the color rendering ability of a light source to a reference light source. The closer the index is to 100, the better the color rendering ability.
Each CRI level is suitable for different uses.
1.3. CRI Parameters and Their Meaning
CRI below 60
This is a low color rendering level. The light causes significant distortion of the colors of objects, making it difficult to accurately perceive true colors.
Lights with a CRI below 60 are usually only used in technical areas, warehouses, or places where high lighting quality is not required.
CRI from 60 to 80
At this level, colors are reproduced relatively well but are not truly natural.
This type of light is suitable for auxiliary areas or spaces that do not require high aesthetic standards.
CRI from 80 to 90
This is the most commonly used CRI level today.
Light sources with a CRI above 80 help display colors closer to reality, creating a comfortable feeling and providing a better visual experience.
This is also the recommended CRI level for:
- Homes
- Offices
- Hotels
- Restaurants
- Showrooms
- Shopping malls
- Hospitals
- Schools
CRI above 90
A CRI above 90 provides light quality that is almost like natural light.
This level is often used in spaces requiring very high color accuracy such as:
- Studios
- Art galleries
- Fashion stores
- Car showrooms
- Specialized clinics
2. Why is CRI >80 considered the standard for many buildings?
2.1. Accurate Color Display
A CRI >80 helps to display the colors of furniture, materials, plants, food, and displayed products as close to their true colors as possible.
This is especially important for commercial spaces and interior design.
2.2. Enhancing Aesthetic Value
Light with a high color rendering index (CRI) highlights wood grain, paint colors, natural stone, and decorative details.
The space thus becomes more luxurious and has greater depth.
2.3. Providing a Pleasant Feeling
When colors are accurately reproduced, the human eye observes more naturally, reducing eye strain during work or daily activities.
2.4. Enhancing Customer Experience
For showrooms, stores, or restaurants, high CRI lighting makes products and food more appealing, thereby enhancing the customer experience.
