What is the color rendering index of the luminaire?
Discover the color rendering index (CRI) of Vanray luminaires, crucial for stage lighting. CRI measures how accurately a light source reveals colors compared to natural light. A high CRI ensures vibrant, true-to-life colors, vital for performances. Learn why the CRI of stage lighting by Vanray sets the industry standard in illuminating excellence.
The fidelity of the light source to the color of the object is called color rendering, usually called color rendering index (Ra).
The light source with high color rendering is better for color reproduction, and the color we see is closer to the true color of things. On the contrary, the color deviation we see will be relatively large.
There are two kinds of color development:
Faithful color rendering: Can correctly represent the original color of the substance to use a high color rendering index (Ra) light source; its value is close to 100, the best color rendering.
Effect color development: to clearly emphasize a specific color, the performance of beautiful life can use the method of adding color to enhance the color effect. The use of low-color temperature light source irradiation can make the red more vivid. The medium-color temperature light source is used to irradiate the blue with cool feeling; The use of high-color temperature light source irradiation means that the object has a cold feeling.
