What is TM-30-15 (TM-30-18), and should I use it?

TM-30-15 is a color rendering index system published by IES (Illuminating Engineering Society).  A color rendering index system indicates how well a light, when shining on objects, can reproduce the object’s color accurately (compared to a black body radiator – e.g., the sun).  TM-30-15 is next in a line of predecessor CRI systems (CIE CRI, GAI, CQS), each intended to improve on previous designs.  In this article, we explain TM-30-15, its advantages, and why it’s important.
