A funny thing comes to mind in reading this discussion. I recently watched a you tube video of a couple of guys smashing flourescent tubes on each other. They should all be dead soon from mercury poisoning (not dead yeat). Now we are making a huge fuss about the even smaller amount of mercury in a CFL.
Not trying to dismiss the issue but we can get pretty caught up in the hype. I would like to see a lamp disposal method that is more ecological. Oh the burden of all those relamping projects and the smashed tubes.
