Thank you for the reply. My reasons for going toward the Vero line are fairly non-scientific: I see a lot of people using them, they are capable of high PAR versus commercially sold fixtures, and they seem to be financially reasonable to build with. When I first started thinking about setting up another aquarium, the 18s were all the rage, so I just went with the "bigger is better" approach and focused on the 29s.
Regarding "looks", I'm completely fine with this light being either yellow or white in appearance, as this aquarium isn't meant to mimic a reef setting. Looking at the spectra you posted, it appears that the 5600K hits better at 450 nm but is flatter at longer wavelengths, whereas the contrary holds true for some of the other color temp options. the 3000K might be better overall? My main question is whether those differences have any biological impact on plant growth or viability. Am I overthinking this aspect?
I do appreciate the help!

Reason: I found the difference between Decor and other: higher CRI
