Did the CRI for the LEDs you bought match that which was listed or did they even have a CRI stated? I'm willing to spend extra for high CRI but so much junk on Amazon outright lies about being UL listed, it wouldn't surprise me if they started lying about CRI once they realize it is a selling point.

Yeah, they claimed a CRI of 91 but it was closer to 70, I think. (Measured with ArgyllCMS and a Colormunki Photo.)

You could tell it was wrong just by looking. It wasn't a measurement that only appeared by looking at it with expensive equipment; you turned the lights on and instantly though "this is completely unusable". I only measured it to see how bad it was.
