Yes you can get around 12W out of them with the right setup. The total efficiency is around 50% so thats 24W from your legs.
Basically every led you put in draws ~1.8W. Details
here.
At low powers the drag is not noticeable. I'm drawing about 9W with a 5 led setup and will be going back to a 2 or 3LED light because over a night it adds up. 3leds is plenty of light. and 2 is fine and 1 is more than a 3w halogen.
People rave about the schmidt hubs but the new shimano 3n80 is likely just as good.
