I read the (quite comprehensive) wiki article [1] to get some perspectives. I think we can all agree that excessive light is undesirable, but there's some subjectivity in determining what constitutes "excessive" lighting. I grew up in a highly urbanized environment (I confess I'm not a nature person), and lighting was very much desirable for safety and for promoting after-hours activity and therefore has a bearing on the economy as well. In northern parts of the world, days get shorter in the winter so artificial lighting can help alleviate a feeling of gloom for some. Some people are uplifted by Christmas lights or by the warm orange glow of a Parisian street lamp, for instance. It sounds like one of those things where different groups need to work together toward a negotiated compromise -- there might not exist an ironclad objective answer as to what's best.
