[RFI] Haolgens AND . . .

[root [knesbitt]]

As someone mentioned previously, the halogen bulbs themselves are not 
the issue, its the low voltage switching supplies which accompany them. 
I have tried several different brands in the various lighting tracks in 
this house and every one of them produce huge RFI. The only solution 
I've found thus far is to replace the low voltage heads with ac units. 
Be warned.
