Everything you need to know courtesy of @alesh http://rollitup.org/t/math-behind.868988/
You are limited to the SPDs Bridgelux has made available in their datasheets. I've already done the 3000K 80CRI curve and came up with LER 332 and QER 4.68. Using that and the 4000K data you could come up with a pretty close estimate for 3500 80CRI. They haven't released any 90CRI SPDs. Whether Bridgelux has that info available but not publicly released I don't know.
I'll see if @robincnn can treat the Vero29 gen 7 90 cri with the lighting passport. We can at least get a good guesstimate of the SPD that way.
