Who knows what the CRI indicator is?

When you look at bulbs or any kind of lamp, you often notice how many products have the number “CRI”, known as “Color rendering index”.

But what is “CRI” and how does its rating affect our decision when buying lighting?

CRI (Color Rendering Index) is a standard measurement of the source’s ability to reveal the colors of objects compared to a natural light source.

The highest possible CRI is 100. It is the same color as natural daylight, which is often found in incandescent / halogen bulbs.

The color of the light is defined as the correlated color temperature (CC9) and is measured in Kelvin (K). Warmer / yellow bulbs = 3500k, and cooler / more blue bulbs = 6500k.
