It's tricky, though, since most LED bulbs use a single wavelength of blue LEDs which get downshifted by phosphors, even in high CRI bulbs, you can have an unnaturally large spike in the blue (often around 450nm).

CRI unfortunately is not a good test, it still can produce very high ratings even when the spectrum is spiky.

95+CRI is an indicator for mostly lack of spikes. Look at Yuji (yujiintl.com), they seem to be the only ones selling actual high-CRI LEDs with sane pricing (i.e., no ideological markup).

I'd like to try one of these out, but at $20 per bulb it's a a bit steep. Are you able to comment how they compare to the Feit Electric 90+ CRI bulbs sold at Costco for a few dollars a bulb?
