The problem is that this spectrometer have low spectra resolution, as it show narrow lines as wide, and makes hard to resolve every line in the spectrum.
I'm also fear that I don't know how to use a spectrometer.
But it definitely looks that a tin was used as a filter for the blue wavelengths.

I am open to anyone who will sponsor me buying $1000 1nm real resolution ocean optics heh ;)

Dor, it is simple to use a spectrometer.

(1) power on
(2) point to the light source
(3) push the button, push the button! ;)

But it needs to be calibrated and the spectra to be aligned and etc... And this is hard to me.

But I think neodymium is still exists in the arctube to bring the CRI to Ra96, while other daylight rare-earths have lower CRI than this.

Any confirmation on Nd usage, patent, technical manual, etc? Or is it just a fantasy?

Nd is relatively weak in red. https://atomic-spectra.net/spectrum.php?elem=Nd

What is the reason to add it?

Modern CMH use Ca and Tm to enrich deep red area.
