The one you posted (TJ) and # 12 modified is fine with a cap like this.

I care about voltage balance because I don't want capacitors exploding on him. I know, silly me. Passive balancing with resistors should be fine for this application.If you care about the voltage balance then you can in parallel with a resistor for each capacitor, or you have some other better ideas?
Thanks for the clarification and the circuit diagram.The one you posted (TJ) and # 12 modified is fine with a cap like this.

Thanks for the link. I hadn't heard of Mouser before but it looks like they have some good deals.If 5 seconds is enough, 10,000 uf @ 10 V
Here's a page of them starting at $1.42
You can search for the size and shape you want.

Where exactly would it need to be placed in the circuit? Like is shown in the section "Basic capacitance multiplier circuit" at http://www.radio-electronics.com/info/circuits/transistor/capacitance-multiplier-circuit.php?the cap value could be reduced down below 1000 uF if a transistor is added to the circuit
Sorry if this seems like a basic question, but how would I know what size capacitor I need if I use a transistor?yes, drawing 2, except your R1 is a diode.
Thanks for the very helpful circuit diagram!What I had in mind was this:
Bias resistor should be <= 10k; Not 100k
No battery, no power.Yes, having the LED fade when I disconnect the battery is exactly what I want.
One is used to bias the transistor, limiting cap discharges current, and the other one is used to limit LED currentI'm curious why there are two resistors in it rather than just one?
But how would that help out given that the energy from the LED is coming from the capacitor in question?the cap value could be reduced down below 1000 uF if a transistor is added to the circuit
