Technology of D50/D65 (D50/D65 Standard Technology)
White is D50/D65 standard technology?
Many people often experience that the color of clothing seen inside a clothing store is different from the color of clothing seen outside the building under natural light (sunlight)
The average color rendering index of LED artificial light for indoor lighting normally used is 75Ra to 85Ra, and the closer it is to 100Ra, the more likely there will be no color distortion.
In particular, in the case of mass production of automobile paints, colored fabrics, color printing, colored carpets, etc., for accurate color quality inspection, the artificial light must have a color rendering index of over 95Ra.
Artificial light lighting that satisfies the Visible Light (Mivis) max 1.0 and Ultraviolet Light (Miuv) max 1.5 standards is required for the Metamerism value. To this end, the International Standard (ISO) standardizes and uses the standard.
In the past, mercury fluorescent lamps D50 and D65 standard lamps that satisfy the international standard color matching index have been commercially available around the world, but production and sales have recently been banned in each country due to global environmental pollution and “Minamata Convention” issues. Therefore, GLB Tech developed D50 and D65 LED standard lights that can replace mercury fluorescent lamps for the first time in the world, and is currently producing and selling them. In addition, we are in the process of registering or examining a technology-based patent that can manufacture D50 and D65 LED standard lighting in global advanced countries such as the United States.

What are the advantages of D50/D65 standard technology?
The color rendering index (CRI) of GLBT's D50, D65 LED standard lighting is typ. 97Ra, visible light condition index (Mivis) typ. 0.5, UV light condition index (Miuv) is typ. 0.9, It is the only LED type standard lighting in the world that sufficiently passes the international standard (ISO) standard and can completely replace the mercury fluorescent lamp type standard lighting with pin-to-pin.
