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?

The decline in quality must have been recent. I compared CREE to every other brand on the market in 2008 - 2010 and per watt CREE was exceptionally brighter and ran cooler. There were few DC to DC bucker failures. Common sense has to be applied. Many lamps with CREE infrastructure only had adequately cool P/N junction temeratures when air was passed over the heat sink. For prissy me, temps are limited to 50 C. Stores that have my high energy LED lighting (50 watts consumed) have not failed after 10 years of use minimum 5 hours per day.
Over temp on the junction is the primary cause of non defective manufacture failures of the CREE. Stress on the substrate is the other. I had to use USA silver bearing heat grease and with the 300 watts consumed shop lamp the heat sink was hard black anodized with 2 full sealed Pabst 120 volt fans and a Meanwell power supply. The chips are driven at full power and illumination intensity is incredible. Far brighter than (2) 400 watt metal halide lamps with a much wider flood pattern.
And GDEtrailer thank you for font separation between published and personal data. Excellent idea.
Heat sinking is the bugaboo with LED technology. It amplifies unit cost times ten.
HINT Up to the present when you see operation voltages 9-30 volts the lamp infrastructure is CREE. The lower the voltage the easier it will be on the bucker. My high wattage lamps must be fed 36.1 volts optimum. They are protected by a precision fuse in case of a shorted chip. Color temperature is 5.1K
