And if you load these four spectra(as read with an i1) into the
i1Share app you'll see why all this happens. Load the 2 RHEM
colors into "Evaluate:Accuracy" reference and sample circles.
Then load the 2 light sources(GTI and JUST) into "Evaluate:Light";
sample 1 and sample 2.
Since RHEM strips are especially susceptible to red metamerism
and the JUST tubes have a sharp drop beyond 650nm, you've
got metamerism even though the JUST lights DO have a
higher CRI. Go figure...

And amusingly enough if you hold one of the GATF/RHEM color indicator
strips under a Just lightbox you get stripes, even though the color
temperature (measured with an eye one) is 4997 Kelvin.
