CREE Has Been Purchased New LEDs In The Works
Details are sketchy but CREE hinted silicon carbide-based LEDs are in the works. 50+% less heating. Much more efficient. Silicon Carbide?

Designing by conservative thermal limit in the P/N Junction is the only way to go in my book. There is of course an absolute limit. A massive or cooled heatsink leaves the thermal interface as the remaining point. I use Arctic Siver as the heatsink compound. Beryllium is better but toxic. CREE used to have the best thermal interface between the diode and substrate. But I am getting old and steadily losing contact with recent developments in the industry.
Were your lamps the entire structure CREE or just the emitters?
