> very good colour rendering The one area where everything but good old fashioned incandescent lights fail. Makes me wonder if anyone is working on applying quantum dots to LED lamps.

There are plenty of LED that is CRI 95+. Is that not enough?

  CRI is a pretty worthless measurement, it only reflects the rendering of color in a specific CCT. It’s fairly easy to make a high CRI warm bulb because it can suck at reproducing the lower end of the spectrum (blue and green), or a cool one where it sucks at the high end, but a neutral temperature isn’t feasible due to the spiky nature of light emitted by white LEDs.

    Even these? https://www.waveformlighting.com/high-cri-led https://www.waveformlighting.com/high-cri-led

      My wet dream is a properly programmable LED light source that will give you great customization of its spectrum, simulating any sort of outdoor lighting conditions.
