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?

My beef with Cree is their success also caused severe damage to the brand name. Every Tom Dick and Harry on eBay, Amazon, elsewhere is happy to proclaim their products contain Cree LEDs. This is hardly the case, and is especially evident when your lighting gizmo quickly fails, while delivering a less than useful light quality (cri and temperature).
I build all my own LED lights whenever possible, and use almost exclusively Lumileds products, purchased via a secure supply chain, to avoid counterfeit products.
Wikipedia has a nice article on luminous efficacy, which also covers the limitations behind 300lm/w for "white" LEDs.
