Description

In commercial spaces, we have been living under a color quality driven, in large part, by maximizing efficacy.  This presentation would be to show a collection of evidence to support a more preferential color rendering.

In 2015, the IES published TM-30-15 as a more complete approach for measuring color quality (i.e., a new CRI).  A key purpose was to assure that new lighting technologies do not enable manufactures to provide a misleading metric.  To show the value, there have been a number of recent scientific studies to identify a more preferred color rendering.  In a somewhat unique circumstance, some of these studies were performed independent of lighting manufacturers, and thus present an opportunity to obtain an un-biased summary of findings. 

This presentation will include a summary of those findings, which when combined, provide a compelling set of experiments for measuring preference. “Non-scientific” findings obtained by Focal Point as we experimented and lived in an environment with the targeted spectrums will also be presented.
