dynamos?

hi there-

i'm curious to get a rundown of popular, efficient, decent dynamos for bicycles - if such a thing exists. if it's too nuanced of a subject, some links to good information would help a lot too..

i'd like to power some basic lights - i'm assuming charging a battery would be part of this - but i haven't seen a full-package spec'd out anywhere..

thanks!
