Use this one. I have to believe it's pretty accurate. Apogee set it up expressly to calibrate their quantum meters.

Assuming I have the inputs right (I just used Berlin, since I don't know your exact location), your measurement was close to what it predicts for noon. The brightest light is actually later in the afternoon. They also show the sensitivity to various parameters:

It's actually a pretty great site.

Bridgelux need to get there shit together and take some lessons from Citizen when it comes to SPD's
All we get is some shitty hand drawn graphs for 3000K 80 CRI; 4000K 80 CRI; 5000K 70 CRI and 6500K 70 CRI
Maybe @Stephenj37826 can hit up a GEN7 90CRI under the spectrometer.
@Rahz

You guys may find some info in this thread.
Note that 90 CRI cobs show up as 95 CRI under test.
80 CRI cobs show up as 85-87 CRI under test

Here is 3000K 90 CRI Vero 29 test with Lighting Passport. Vero 29 SE so its Gen 7

Raw data attached

who ever requested the data can check the Math Vero 29 3000K 90 CRI.zip for accuracy
