Hello HDS owners

The R9050 in the part number of the Niciha LEDs is a CRI code denoting an Ra (CRI) of 90 CRI minimum and an R9 value (rendering of the red swatch from CRI) of at least 50.

Actual measured CRI will be higher, but may vary slightly from sample to sample and with drive current; it's likely around 93-95 in practice.

I found this old screen shot from the NC27, 30, 35 & 45 group buy thread. It has the lumen and CRI values of the 3900°k XPL and the NC30 & NC40.
