The IES recently approved TM-30-15, a new method for evaluating light source color rendition. During this September 15, 2015 webinar, presenters Michael Royer of Pacific Northwest National Laboratory and Kevin Houser of Penn State University covered the basics of the new method, while also discussing the development process and ongoing steps toward widespread adoption. The webinar included an overview of the hierarchy of individual measures and graphics that are available to describe a light source’s color rendition with various degrees of specificity, provided examples of how they can be applied by various users, and demonstrated the Excel tools that are distributed with the document.
This webinar was followed by another webinar, A Technical Discussion of IES TM-30-15, that focused on the underlying math and color science that make up the calculation engine, as well as the details of how the hierarchy of measures is calculated, in order to provide TM-30-15 users with a deeper understanding of the meaning, accuracy, and limitations of the measures.
