Don, assuming each diode has a voltage drop of 3.6 volts, your series

assume 20 mA) The red dot marks the positive terminal of the capacitor.

Speaking of LEDs... I'm wanting to use a large capacitor to level the
voltage off half-wave rectification (single std.diode isolating the
capacitor - [k.i.s.]) - for a big series string of 40 white LEDs that are
hooked up direct with a 100ohm resistor in series. It works, but flickers at
60hz. It
