By Jason Livingston (Studio T+L), Michael Royer (PNNL), Lorne Whitehead (University of British Columbia) It seems that every month there is a new metric proposed to quantify the performance of light sources, particularly with respect to spectral properties. One of the latest examples is Average Spectral Difference (ASD).
