TM-30: A More Accurate Way to Measure Color
The Illuminating Engineering Society (IES) partnered with lighting design researchers and specification and manufacturing experts to design TM-30, an improved color rendition metric that more accurately evaluates the natural rendering of colors by light sources. With guidance from Soraa scientists, TM-30 is a more complete approach for measuring color accurately compared to CRI.

More Science
TM-30 uses state-of-the art scientific advances in color science to measure light source rendition. As a result, it is more accurate than the traditional CRI method—especially for narrow-band spectra. |
More Accuracy
The CRI fidelity index uses 8 color evaluation samples, while the TM-30 fidelity index, Rf, uses 99. TM-30 also provides more insights with the gamut index Rg, which indicates a color's saturation when illuminated by a light source. |
More Insights
TM-30’s color vector graphics offer additional information about saturation levels and hue shifts. Several TM-30 indices deliver more color rendering insights, including the color fidelity of reds and skin tones. |
99 Color Evaluation Samples. Infinite Possibilities.
TM-30 employs a set of 99 color evaluation samples (CES) to determine fidelity for a more complete measurement of color. Optimized for real-world applications, each of TM-30’s 99 color evaluation samples were selected from more than 100,000 reflectance properties for real objects.
