Soraa supports TM-30 as a superior color test for the lighting industry

Soraa, a developer of GaN on GaN LED technology, today announces its support for advances in color science and the new TM-30 method released by the Illuminating Engineering Society (IES). TM-30 uses an optimized calculation method to preclude the errors found in the color-rendering index (CRI), the current industry standard.

As a leader in developing products with superior light quality, Soraa is a strong supporter of advances in color science. Illuminating the way, Soraa Chief Scientist Aurelien David served as a lead technical contributor for the new TM-30 method.

“IES’s TM-30 method offers significant progress over the CRI,” said David. “For customers, TM-30 will provide better insight in to how the colors of a light source compare to colors under natural light. And for manufacturers, the information found under TM-30—combined with other aspects of color science—will be key for developing better products and optimizing the trade-off between color rendition and other criteria of light quality.”

The TM-30 test was developed to provide a more accurate indication of the color rendition of an object by comparing the color of the object under a test source (a LED lamp, for example) to those under a reference illuminant (a standard emitter such as idealized sunlight or filament bulb, depending on the CCT).  By doing so, the test will indicate if the colors under the test source are different from natural colors—providing a more precise indication of color fidelity.

TM-30 distinguishes itself from the CRI test in two significant areas. First, it uses state-of-the-art color science to test a light source’s color rendition of more color samples, which will preclude the inaccurate predictions of rendering seen with the CRI—in particular for narrow-band sources. Second, it provides users with more information: the color fidelity index Rf is now complemented by a color gamut index Rg and by a color vector graphic, which further characterize the appearance of colors.
