Haitz's Law and 200 Lumen/Watt Cree LEDs

Cree has released an LED with 200+ Lumens/Watt. 

 Haitz Law Wiki

"every decade, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light."

Built on Cree’s revolutionary SC³ Technology™ LED platform, the MK-R LED delivers up to 200 lumens-per-watt, enabling lighting manufacturers to create the next generation of high-lumen indoor and outdoor LED lighting systems. MK-R LEDs are available in EasyWhite® color temperatures, providing the LED industry’s best color consistency for designs that use only one LED. For systems that use multiple LEDs, MK-R enables manufacturers to use fewer LEDs while still maintaining light output and quality, which translates to lower system cost.
