Shot through a quantifying spectroscope. Only $9 on Amazon, totally worth it since I found out that the RGB color model is a scam perpetrated by our nervous system. This is of course for Pykxil project, but also fun for, in this case, checking out just how True Color the True Color CFL lamps I have are (there are still noticeable peaks in the spectrum but a lot of the gaps are full, it’s actually pretty flat compared to other CFLs  - except for that huge gap between green and red).
