2 to 10 miligrams of mercury is piddleingly small. and since the vapor pressure and temp are pretty low it will be no longer vaporized very quickly and thus of no real danger.
Who says incandesant lights don't flicker, just listen to one with a light probe and tell me that's a stable light source. Now, go check the mercury output of that big new coal fired power plant that is probably going in somewhere near you, there is a REAL problem, a few fluorescant bulbs and the mercury that is no longer in vaccines ain't nothing to the coal plants but everybody loves coal these days. Even if you are paranoid, it doesn't mean they aren't out to get you! you just don't really know how. Tom
