@SwiftOnSecurity yeah, it was a major breakthrough and it's a big deal.

the next frontier is solving the green gap problem. right now we don't have efficient semiconductors that have a bandgap with a wavelength in the range between green-yellow and red-amber.

if we can find one, we can stop building white lights that have such a strong blue peak, and make very high efficiency white lights that run the full gamut of the Planckian locus.
