Sorry, I refuse to use poison in my home. A LITTLE Mercury is more than the amount that should be, which is NONE.
Using that logic, I guess schools and offices are dangerous places to be, since they use fluorescent lights everywhere. 
No, because they're mounted on the ceiling, and they virtually never break in a school setting. Not to mention they have the resources for cleanup.
Bottom line, i wouldn't replace the lightbulbs I'm using now, that give me no problems, for a totally inferior product.
