Searching around on the local Mouser site I've come across the following two options. The first I've seen mentioned and recommended here and other sites (MIGRO, etc.) and the second I haven't. I'll link to the data sheets. The price difference is so small as to be meaningless. The respective data sheets suggest they were both released in 2018.
CXM-32-35-80-54-AC40-F5-3 - Generation 4, CRI 80
The CRI 90 version is available, but in a minimum purchase quantity of 300, so I'm limited to the CRI 80 option.

The Sensus Series data sheet states "Matching the human perception of “Pure white” light... Designed to provide the look and feel of ceramic metal halide lights." But since the color temp is 3500k that shouldn't really matter, should it? It's also 90 CRI compared to 80, so I'm assuming better reds. Another difference I noted was that the former is listed as being "a product with chromaticity on the BBL," whereas the Sensus states it's "Below the Black Body Locus (BBBL)." I don't know enough about color to know which is preferred or if it makes any notable difference for growing. I did a little reading on the subject - just enough to give me a general idea while realizing most of the details were going over my head on only a quick read. I did read that it doesn't really matter at temps below 5000k, though the Chromaticity Bin Structure charts (page 3 in each data sheet) do look different.
I haven't found any real mentions of the Sensus Series online (grow forums) other than for places like Mouser that sell them, so I thought I'd try here to see if anyone's had any experience or opinion. On the surface, CRI 90 beats 80, but not coming across any mentions I'm a bit hesitant without confirmation from those more in the know.
