[TowerTalk] Green Power Lightbulb QRN

[Dan Kovatch]

I have replaced several lights with the neon 'Greenie Lights' and so far 
have noticed no ill effects. We have several 3 ways also and most of the 
others are in single fixtures, including two in the shack and on our desk by 
this computer.

 I think it's a bad batch or maybe your house is wired funny (tongue in 
cheek but worth checking anywho)
