CRI is a measure of the ability of a light source to render the original color of the object illuminated by the light source. The original color is defined by the color of the object when it is illuminated by sunlight.
The closer the color of the object rendered by the light source is to the color of the same object under the sun, the higher the color rendering index of the light source. The value of CRI ranges from 0 to 100. By definition, sunlight has a perfect CRI with a value of 100.
Note: The higher the CRI value, the better the quality in terms of the light source&#;s ability to render colors. This is important for lighting applications where color is important.
For example, if you need to light up your meat counter, then if you don&#;t want the meat to have an old, brown hue, then the color rendering of red is essential. The best CRI is to faithfully replicate the colors of goods and products in the store.

You may have noticed the produce area where the supermarket sells vegetables and fruits.
When using a light strip with a high color rendering index, the product presents a natural saturated color, which looks juicy, shiny and fresher. Therefore, they are clearly more attractive to customers.
The same goes for fresh meat. Under the light zone with high color rendering index, the meat is purple red and looks fresher. If the CRI is lower than 80, the color of the illuminated object will be distorted, as if it is covered by a gray veil. The object looks lacklustre and dull.
From the perspective of protecting human eyesight, long term use of light strips requires a CRI higher than 80. Light with a CRI lower than 80 will affect the human eye&#;s ability to distinguish colors. Prolonged exposure to light with a color rendering index of less than 80 may cause various vision problems. you may have some question about the CRI, what&#;s different with high CRI and low CRI? here you will get answer: What is CRI? What is high color rendering index?

Introduction
The LED screen market is booming, with many options available, particularly from Chinese manufacturers. However, finding a high-quality product can be challenging. This guide provides essential tips to help you navigate the market, understand quotations, and ensure warranty terms to avoid costly mistakes. At Avendor, your Pro AV partner since , we strive to help you make informed decisions and avoid the pitfalls of low-quality screens.
Why is it challenging to find high-quality LED screens?
The LED screen market is saturated with options, especially from China. While many manufacturers are reputable, others offer lower-quality products. The cultural approach in China often emphasizes building business relationships and trust, which can lead to challenges in distinguishing between high-quality and subpar products. According to William (Bill) Craig, an LED display specialist, Chinese manufacturers often make no attempt to discuss the actual components that make their products good or bad. Instead, they focus on building friendships and providing vague quotations.
What should I watch out for in LED screen quotations from Chinese manufacturers?
Chinese manufacturers typically provide quotations that focus on basic specifications like pixel density and the number of cabinets, avoiding detailed discussions about the quality of components. This lack of transparency can make it difficult to gauge the true value and performance of the screen you're considering. Sita Liang, a business developer, points out that until the product is in hand, its quality is uncertain, and the initial samples might not reflect the final product's quality.
How do Chinese manufacturers handle warranties?
Warranties from Chinese manufacturers can be problematic. Often, the terms require the buyer to ship the faulty screen back to China for repairs, a process that can be both expensive and time-consuming, sometimes costing more than the original price of the screen. It's crucial to fully understand the warranty terms before making a purchase to avoid unexpected costs. Bill Craig notes that many factories are simply trading companies with no real focus on warranty or support.

How has the industry changed?
After the first LED installations in North America, the industry saw rapid changes. Initially, the market became oversaturated, with more factories than opportunities. Many manufacturers turned into trading companies, focusing more on quick sales rather than long-term support. Today, only a small percentage of factories genuinely support their products, while others struggle to maintain relevance. As Bill Craig observed, "most screens are made by Chinese manufacturers, and only about 1% truly support their products."
How can I ensure I'm buying a high-quality LED screen?
To avoid the pitfalls of low-quality LED screens, follow these tips:
-
Research Thoroughly: Investigate potential manufacturers. Look for reviews and testimonials from other buyers.
-
Request Detailed Specifications: Insist on detailed technical specifications, including information on components like LED chips, drivers, and power supplies. Adnan Rishad Chowdhury, a business development manager, emphasizes the importance of focusing on quality rather than just price.
-
Understand Warranty Terms: Ensure you fully understand the warranty terms, especially the process for handling repairs.
-
Ask Questions: Don't hesitate to ask specific questions about the products. Reputable manufacturers will provide clear and comprehensive answers.
Why is it important to get detailed product information?
Detailed product information allows you to make an informed decision, compare different products accurately, and understand the quality of the components used. This can prevent costly mistakes and ensure you invest in a screen that meets your needs and expectations.
Can building a relationship with the manufacturer still be beneficial?
Yes, building a good relationship with the manufacturer can be beneficial. However, it should not come at the expense of transparency and quality. Ensure that the manufacturer values both the relationship and providing detailed, accurate information about their products.
Conclusion
Navigating the LED screen market requires diligence and attention to detail. By thoroughly researching manufacturers, requesting detailed specifications, and understanding warranty terms, you can avoid the pitfalls of low-quality screens and invest in a high-quality product that meets your needs. Remember, a transparent and reputable manufacturer will be your best partner in making a successful purchase. As Ronni Anne Spang aptly put it, "The pain of inferior quality is felt long after the elation of a bargain price is forgotten."
