You need an inductor with two windings. See page 982, 998, 1000, 1002, 1022, and 2302.

You might be able to use the isolation transformer from an old Ethernet card.

see my discussion on this circuit on Talking Electronics website under: LED Torch Circuits.
Adding a capacitor reduces the current to 30% of the original.
