The color rendering index CRI may be replaced and a new color measurement standard will be released

Recently, the 2014 Solid-State Lighting Ecosystem Summit (SSL Ecosystem Summit) has concluded successfully. According to foreign media reports, industry experts attending the summit pointed out that the color rendering index (CRI) is usually used to define the color quality of LED lights, but it is not perfect in color perception measurement and will soon be replaced by other color measurement standards. Terry McGowan, technical director of the American Lighting Association (ALA), pointed out that CRI does not adequately represent color perception. He said that back in August, the Illuminating Engineering Society (IES) had proposed to the government to stop using the CRI to define energy regulations. The CRI will likely be replaced by a combination of the Color Quality Standard (CGS) and the Gamut Area Index (GAI). N. Nanrandran, director of the Lighting Research Center at Rensselaer Polytechnic Institute, said that the university's LRC ASSIST Program is combining CGS and GAI and will soon replace CRI.
