This is the smallest member of Cree's newest line of multi-die high-output LEDs, mounted on a direct-thermal-path copper MCPCB.  The XHP35.2 HI is domeless from the factory, providing higher spot intensity at the expense of some lumen output. 

The XHP35.2 is a 12V nominal rated LED.  Please read the datasheet for more forward voltage information. 

All MCPCBs are copper direct-thermal-path.
