There's a second series set about 20 years later, but it's much less lighthearted.
You could try watching Magical Lyrical Nanoha. It's pretty well a standard magical girl show ala Sailor Moon (minus the ensemble cast, there's only two magical girls involved here), but a little more boyish. There's a few 'oh fuck' moments thrown in for good measure, but it's still fairly light overall. Only 13 episodes, not counting the sequels.
Bear in mind that I'm a fairly morbid sort of person, so whats lighthearted to might not be to you.
