As we moved into our new place, we discovered three of those twirly-bulbs: one in our bedroom, one in the hallway, and one in the kitchen. We hated the blue light these cast on these rooms, so we replaced them at our first opportunity.
We have a long bulb in the kitchen, a secondary light, that produces a more yellowish light; we like this light, except that after it's been on for a few minutes, it buzzes, and it gets louder as time progresses. And now my desklight is beginning to do the same.
Why can't flourescent lights just burn out like good incandescents do? Or just last forever, like those modern LED lights are expected to do? Instead, they flicker, or they buzz, or both...and I'm certain that some fluorescent light designer, somewhere, is probably working on even more ways for fluorescent lights to be able to torture people.
Of course, all this would only be a minor annoyance, if it weren't for the fact that Government has banned incandescents, starting in 2012. Thus, I will now be left with the choice of evil fluorescents, or expensive and untested LED lights.
Why, oh why, can't Government just leave us alone?!?
 Not to mention that both "features" can cause migraines, or at least, make the life of someone who already has a migraine considerably more miserable!
