Introducing TM-30-15
Accurately quantifying the color rendition characteristics of a light source just got a whole lot easier!
 

For over 50 years, CRI (Color Rendering Index) has been the industry standard for measuring a light source's ability to render specific colors. Even though it's been the standard since it became official in 1965, it has some shortcomings that have remained unaddressed for the past five decades.
  • It doesn't account for many saturated colors.
  • It doesn't account for skin tones.
  • It is calculated using the test source against an incandescent lamp (black body radiator) to find the ratio of difference over a small number of samples.

 

  • It's limited in how much information it offers. For instance, you can't tell where the source is over- or under-saturated at specific wavelengths. If the source doesn't have that color, then that color won't be rendered in your space.
  • Because there are so few color samples in the test, it is possible for manufacturers to game the system by having lamps hit where the test colors are in the spectrum.
To help eliminate the flaws that are inherent with CRI, the Illuminating Engineering Society (IES) created the Color Metrics Task Group in 2013. This group created a new Technical Memorandum (TM-30-15) entitled "IES Method for Evaluating Light Source Color Rendition." TM-30-15 relies on separate fidelity and gamut metrics, and utilizes 99 test samples that are more representative of real-world objects as opposed to the pastel samples that are primarily used for the baseline CRI metric. The new color metric fairly and accurately characterizes both LED-based solid-state lighting, as well as legacy sources. And, its more comprehensive measurement methods make it virtually impossible for manufacturers to cut corners.

You can learn more about TM-30-15 here. And, the full technical memorandum can be purchase from IES here.
