[TowerTalk] Green Power Lightbulb QRN

TT:

     I picked up (but didn't purchase) a CFL bulb package the other day and read that the gizmo contains mercury.  The package simply advised something along the lines of, <Dispose of in accordance with your local laws regarding mercury> and <In case of bulb breakage open room windows for several hours.>

     Has anyone looked into their own local laws regarding mercury disposal?  Will we have to stockpile the dead bulbs until a suitable, geologically-stable respository has been constructed in Rocky Flats?

There is a huge variability in RFI among various brands and models.  In 
theory, they meet FCC standards (Part 15? or maybe exempted as lighting 
equipment or because the switching rate is low enough or...), but that 
might be a pretty loose standard.

Some trial and error is called for. And, then, even if it's the same 
model, it might still be variable, as they change manufacturing 
processes and designs.

BTW, the noise is mostly carried on the power lines, and radiated from 
there, so perhaps some heavy duty RFI filtering (close to the lamp) 
might help?
