Hi Paul,
I was puzzled about the fail my self so i went ahead and hand delivered the full CU 495 to STA it was really nice to meet an LPF member in the flesh. Ok well i went down to my shop and through the diode alone on the Power meter and the diode is great putting out the norm. The nano failed as with all the lower power diodes as the 495,480 and the 505's the Nano's are set to 275 respectively . So hey i guess it luck of the draw even with the drivers . The best part is i am glad that STA is a happy camper and i also gave him a 14500 cell in a cool little case with the build. STA treat it right wit low duty cycle and no Gorilla tactics buddy LOL!!! Paul thank you for the reply buddy.
