I wrote a script to pull down all of OSRAM's optical data packges, extract the spectral power distribution data, and run colour quality analyses on them. the reason for doing this was to take a look at the correlation between CRI Ra (the typical CRI number you'll see advertised), CRI R9 (the saturated red reproduction figure from outside the standard CRI Ra range), and the TM-30-18 CFI quality metric.

CFI is a better measure, but the advertised CRI figures are still representative past CRI 90.
