Just a comment to an earlier post I'd made-I thought the OP was talking about overall "green" operations, including waste disposal, etc. You guys have any idea how many fluorescent tubes are on a 744, and how often they're changed, and where all the mercury vapor in the tubes goes, and where all the glass goes, and how these things are shipped all over, when every F039WWBCAC tube I've seen in the last 10 years is made in Mexico? Where I'm at, it's illegal to throw one in the trash. I'm not advocating saving fuel by switching lighting, FFS.
