Thanks to all for the replies.
I think I'll end up getting the parts and breadboarding it test.
I may be thinking of this wrong, but I'm imagining a sort of convergence of voltages at the led cathode pin, where the V1 voltage starts dropped by. If I have a rising voltage from 0 to 13v at the gate, with the transitor turning on around 6v, I don't understand how am I building up voltage over the V1 of 13, higher than any voltage source in the circuit.
Before I posted, I did 1 more thing, since the gate has some capacitance, I just replaced the mosfet with a 180pF capacitor and while goofing around with it I changed the dropper resistory to .1mohm.
Green= V1, 6 volts across
Blue=Anode side of diode, near 6 volt across
Bluegreen= V2, starting at 0 and rising to 13 volts.
Red=Cathode side of diode, rising from 6 volts to near 15 volts.
I didn't anticipate that. I'm worse off than I ever thought. V=IR right?
