  • Thank you for this! The only part I don't quite understand is a the end where, "If you solve for the voltage drop of the resistor, you get 8.1V". I understand that 12V - 3.9V = 8.1V, but what about accounting for the voltage drop from the resistor? It's been a while for me, pardon my ignorance!

  • What's the forward voltage and forward current of the LED? I don't see them in the description or data sheet.

No public wish lists :(
