If you’re ever taken out to dinner to a restaurant with fluorescent lighting, you can be pretty sure that your date is an idiot. That’s the least flattering kind of light known. Well, maybe it’s not as bad as yellow sodium street lights, but truck yards are not exactly places for romance either. Fluorescents are heavily blue, which causes skin to look less healthy and shows up blemishes. If a restaurant uses it, you can be sure that they’re cheap, which also doesn’t speak well for your date.
But fluorescents are the lighting of the future! Or at least they will be next year in the US, when 100W incandescent bulbs will no longer be sold. By 2014 even 40W will be illegal. Everyone else is banning them too; they’re just too inefficient. Incandescents have had a 130-year run since Edison’s first plant, which is a pretty long for a technology ( E.g. steam locomotives only lasted for 100), but they’re done for. Unfortunately, fluorescents aren’t that good a replacement: they’re slow to start, hard to dim, not as reliable as claimed, contain mercury, and the light color is poor.
So everyone is working on the next technology after fluorescents, LEDs.
