Being an astronomy nut, I was actually pretty stoked to read about the proposed ban on incandescents. Low/High pressure sodium lights are easily filtered out when viewing or imaging the night sky. Incandescents however emit light across such a broad spectrum that it simply cannot be filtered out. Even using very narrow emission line filters (e.g. 3-5nm) filters doesn't cut it.

The street lamps near my house are low pressure sodium, but I live in an area where the local inhabitants insist on keeping their homes lit up like it's broad daylight. I figured at least my suffering was coming to somewhat of an end in the near future. I guess now I'll have to buy lightbulbs for all of my closest neighbours. Alas.
