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?

I was surprised to learn from a lighting industry rep a year or so ago that Cree fixtures were having issues with early lumen depreciation and worse, bad color shifting. They used to be at the top of the heap.
We redid the facade lighting on a prominent downtown high rise about 10 years ago with Cree fixtures. What was most impressive were the optics. The fixtures are mounted about 1.5 M from the wall & then wash down for about 25' for each row. The level of illumination is very nearly uniform from top to bottom. I drive by it 3 or 4 times a year at night & there have been no chip failures & color uniformity is still excellent.
