I ended up using an LM 317 to provide constant current. It gives a nice gradual turn-on of the lamp, excellent for my application (a miniature lighthouse). An IRF 630 works as an on/off switch.
Simple, cheap and inefficient but has zero quiescent current consumption when the lamp is off.

Now, the next challenge is to plan some scheme to recharge the Li-Ion cells...
