ROTFLOL!!!!!!!
First off, the math is off. 4 mg/CFL x 1000 CFLs = 4 grams. You're now somewhere in the vicinity (sez memory) of one mercury thermometer, which we've been using since the dawn of time, um, the discovery of fire, um, the invention of tools, um, the bronze age, um, the iron age, um, the invention of the bagpipe, um, the discovery of that funny stuff good for plugging wind-holes, um, well, a long time ago, anyway.
And last I looked, my kids weren't glowing in the dark. (Kind of a shame, actually, because it would've made keeping track of them a lot easier at night.)
Well, OK.
But I still hate CFLs.
;-)
I missed that one.
What's it called?
