Color Rendering Index - A Guide for LED Lighting

One of the most important aspects of selecting LED lighting is understanding the Color Rendering Index (CRI). CRI is a system that rates the ability of a light source to accurately render color and appearance. CRI ratings are based on a comparison to natural daylight or sunlight of the same color temperature, which has a rating of 100. An understanding of CRI can help you determine whether an LED lighting fixture is suitable for your needs. Let’s take a look at why high CRI is so important when it comes to LED lighting.


CRI is measured on a scale of 0-100, with higher numbers indicating more accurate color rendering. A high CRI lights above 80 are generally acceptable for most applications, but there may be some situations where you need a higher rating. For example, if you’re working in an area where color accuracy is important (like retail or art galleries), you should look for LED lighting with a CRI rating of 90 or higher. Furthermore, many LEDs have lower CRI ratings than incandescent or fluorescent bulbs, so it’s important to take this into account when choosing lighting fixtures.

In addition to color accuracy, and color temperature, other factors also need to be taken into consideration

Importance of Color Accuracy

The human eye is sensitive to subtle differences in colors, so it’s essential that any light source used in space accurately renders colors. If the colors are not rendered accurately, then objects will appear too dark or too bright, or their colors may be distorted. Poorly rendered colors can also cause eye strain and fatigue in people exposed to them for extended periods of time. This makes it particularly important when it comes to commercial and retail spaces where customers may be present for hours at a time.

That’s where the color rendering index and color temperatures come in. CRI is a measure of how accurately a light source renders colors, with higher values indicating better accuracy. Most LED and fluorescent lamps lighting fixtures now have CRI ratings of 80 or higher, which is considered very good for most applications. If you need to render subtle differences and complex color combinations, then it’s best to stick with fixtures offering higher CRI ratings than low CRI.

In addition to the appearance of objects in a space, CRI also affects how comfortable people feel in a space. Studies have shown that light sources with higher CRIs can reduce feelings of fatigue and improve concentration. Lighting has even been linked to increased retail sales, as people can see colors more accurately and make purchasing decisions more easily. Mimicking natural light source indoors has numerous health benefits.

So when you’re selecting lighting fixtures for your space, be sure to consider CRI ratings in addition to other factors like color differences, wattage, efficiency, beam angle, light sources, light bulb, and color temperature A higher CRI rating will ensure that your space looks great and your lighting project.

CRI Rating System

The Color Rendering Index (CRI) measures how accurately a light source renders color compared to natural daylight on a scale from 0-100. A higher CRI rating indicates that an LED fixture renders colors more accurately than one with a lower rating does. Generally speaking, LEDs with ratings between 80-90 are considered good quality; however, some applications such as retail stores require fixtures with higher CRI ratings of 90 or above in order to properly display merchandise and create an inviting atmosphere for customers. skin tones look beautiful lighting quality, with 100 being the closest to natural light. artificial light source compares to sunlight, where higher values indicate more accurate color appearance.


 CRI 90-100

Excellent - All colors are clearly separable 

 CRI 80

Good - Some colors look like the same

 CRI Less Than 70 

Poor - Can't distinguish most colors


It’s important to note that different types of LED lights have different CRI ratings; some may be more suitable than others depending on the application. For example, LEDs used in residential settings typically have a lower CRI rating compared to those used in commercial settings where the accuracy of color rendering is paramount. Furthermore, the CRI ratings of LED lights also tend to decrease over time as the components of the fixture degrade. Therefore, it’s important to regularly replace and monitor them in order to maintain a high-quality illumination environment.

In addition, other factors can influence CRI performance, such as light spectrum, temperature, light bulb, and brightness. Therefore, it’s important to consider these parameters when selecting the right LED lights for an application. Any other modifications to the lighting system such as dimming or color changes should also be taken into account when determining the correct CRI levels.

To sum up, CRI is an important measure of light good color rendering

that should be taken into consideration when selecting LED lights for any application. It’s important to look at the CRI rating of a light source that renders eight color samples, as well as other factors such as temperature and brightness, in order to make sure that the desired quality of illumination is achieved. Regular maintenance and replacement should also be considered to ensure the best possible results as you can see cri scale in the red apple photo.

The Importance of Choosing the Right LED Light Based on CRI Ratings

It’s clear that understanding Color Rendering Index (CRI) is key when selecting LED lighting fixtures; poor color rendering can lead to eye strain and fatigue among those exposed to it over long periods of time, as well as an inaccurate representation of objects being illuminated by the light source itself. The higher the CRI rating, the better light quality you will get; however, this doesn’t necessarily mean that you need the highest possible score for every application – it depends on what type of environment you will be illuminated with your lights. Rufat Lights can help you choose which LEDs best fit your needs so that you get maximum value from your investment! We have an array of options for you to choose from our lighting manufacturers, which are all rated according to their CRI Rating so that you can make an informed decision about your LED lighting choice and light source's CRI and led technology.
