[RFI] T8 4 bulb Fluorescent ballast needed

[Mike King - KM0T]

Gary, if the ballast does not have a label for "residential use" then you will need to either return the fixture for one that does, or replace the ballast with one labeled as such.  Makes a big difference.  Commercial ballasts these days, especially the multi voltage input ones are horrible.
