Webinar: A Technical Discussion of TM-30-15

September 22, 2015 1:00PM to 2:30PM EDT

TM-30-15, recently approved by the IES, synthesizes a variety of recent research to provide a single cohesive system for evaluating light source color rendition. This presentation, “A Technical Discussion of TM-30-15 – Why and How it Advances Color Rendition Metrics,” will focus 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. The 90-minute webinar will be divided into three sections that cover: (1) the derivation and properties of the new set of 99 color evaluation samples, (2) the CAM02-UCS and reference-illuminant methodology, and (3) the TM-30-15 numerical and graphical outputs – and there will be time for live Q&A following each section.

This technical webinar will follow a more general presentation on the basics of the new system and how to apply the new measures and graphics. Attendees are encouraged to view the general presentation and come with an understanding of the basics of color rendering and CRI, as well as any questions they might have on TM-30.
