The color rendering needs in a space vary, so how could one number accurately depict which light source renders colors “best?”
While Color Rendering Index (CRI) provides one metric, TM-30 provides a robust suite of metrics that convey much more information than any previous attempt at characterizing color rendering. Jason Livingston, co-chair of the IES Color Committee, explains what TM-30 is (and isn’t) to Liz and Raelle, and explores how we can use TM-30 when evaluating lighting needs.
