The second generation of multi-die high-output LEDs is here! These are all mounted on a direct-thermal-path copper MCPCB.
You may choose between 6V and 12V MCPCBs. All MCPCBs are copper direct-thermal-path.
Please note that the XHP50.2 has an extremely low forward voltage. It may be damaged by use with an FET driver and high-drain 18650/26650 batteries! Generally, 2x18350 is fine. You may have to add resistance through thinner wires, weaker cells, etc. to use a single XHP50.2 with an FET driver!
