Ceramic lighting tech has actually been available for some time. They were first marketed for use in retail and commercial fixtures as an alternative to unnatural looking yellow-orange HPS bulbs or traditional Metal Halides which dim and burn out more quickly. Similar to a standard HPS bulb except the filament runs at a higher temperature giving them a high Color Rendering Index (CRI), truer to natural sunlight. The upshot was a lamp with the long life of a HPS. As well as a spectrum that couldn’t be matched by the best metal halides, and also capable of putting out excellent PAR measurements.
