Standard Illuminant (D50/D65) - YUJILEDS

Standard Illuminant (D50/D65)

As the standard illuminant of daylight simulation, D50 is widely used for color viewing, color proof, printing lighting, visual color matching industries as norm light. With the advanced technology and development of Yuji LED, we start to customize Beta version D50 LED products. 

As a standard for color matching application, ISO3664:2009 specifies viewing conditions for images on both reflective and transmissive media, such as prints (both photographic and photomechanical) and transparencies, as well as images displayed in isolation on color monitors.

Yuji VTC D50 LED is partly compliant with ISO3664:2009 on chromaticity parameters. 

What is VTC D50 product?

VTC series D50 product is based on VTC series 5000K and is made by some adjustments. 

What is the difference between VTC 5000K and VTC D50?

Comparing to VTC 5000K, Yuji customizes VTC D50 in two different ways:

1. The spectrum of VTC D50 is more simulated for CIE D50.

2. The chromaticity coordinate tolerance is compliant with ISO3664:2009.
