What is the CRI range for LED lighting?

• A. 75-85
• B. 60-90
• C. 20-40
• D. 95-100

Answer: (B)

Color Rendering Index (CRI) gauges how accurately a light source renders colors compared with a reference light. For LED lighting, you’ll see CRI values that span roughly 60 to 90. Many common LEDs sit around 80 or higher, and high-CRI LEDs can approach the mid-90s, but extremely high perfection (near 100) is rare outside specialized products. So, the statement that LED lighting commonly falls in the 60 to 90 range best matches real-world products. The other ranges are less representative. A narrower 75–85 misses the lower end some LED options can have; 20–40 would indicate very poor color rendering unsuitable for most spaces; 95–100 implies almost perfect color rendering, which is uncommon for standard LEDs.
