To add further, lighting isn't just about the lights you use but also your material setups.

For instance, use an old style skin setup (which often includes an ambient/translucent component) with IDL and you'll end up with glowing skin. Might be just what you're looking for as an artistic effect, but for realism it'll look odd.

You've got to consider the whole scene and what you're trying to achieve.
