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?

Will do. I was thinking aloud about the power supplies. I insist on Meanwell. The only complete unit I have encountered down here was a uni voltage 30 watt streetlight. Idiots connected a 120 vac unit to 240. Could not get the chips to fire isolated with 60 volts, and I did not like the heat sink (heavy but limited radiation area) so I chucked it.
What's a hoot is the number of new cars with LED stoplights with failed emitters. You can bet your rear end it's a problem with undersize heat sinking. Must replace entire lamp assembly. Six hundred and sixty dollars for a single Honda fixture. My 12 volt lamps contain just enough emitters to sustain bright light in series parallel @ 14 volts. Too much trouble for automakers.
I do not drive at night even in the city down here. But I wonder how long those mini fans last on LED headlamp modules? My beam pattern is set very low. plus I have a 18 watt spot, all aimed to spot speed bumps and potholes on city streets.
