SS50 AC to DC 10w cree led

Using the AC output of my Honda SS50 to drive a 10w CREE LED. The AC is converted with a 3 phase rectifier to power the buck converter which limits the output to 13.8v for the DC system (with a battery). Another buck converter makes it into 3.3v with constant current limited at 3 amps to drive the 10W LED.
