[RFI] Electronic Fluorescent Ballasts - look for Residential rated

Thanks for the advice Tom.

The local Lowe's sells Philips ADVANCE ballasts. The model ICN-2P60-SC 
is for a pair of T12 lamps, 6ft or 8ft.

The installation instructions in the box have a brief paragraph on the 
last page regarding EMI/EFI. The last two sentences in particular caught 
my eye: "Most ballasts meet the lass stringent Non-Consumer requirements 
for commercial applications. Ballasts meeting the more stringent 
Consumer requirements for residential applications are noted as such on 
the ballast label."

There is no indication on the ballast label that it is consumer rated. 
Indeed, the Philips Technical Datasheet indicates the ADVANCE line of 
ballasts is "Non-Consumer (Class A) rated for EMI/RFI."

Going to call local electrical houses tomorrow, see what they have to offer.

Do you know who might manufacture a consumer rated ballast? How much 
quieter is RF-wise the consumer rated ballast as compared to the 
non-consumer rated device?
