it seems what was once a rare incidence of RFI(Radio Frequency Interference)
with these 'new' digital ballasts is now a common occurrence, with many brands.
IMO, buy the lamp, test it out, if it fails send it back, get it replaced, as the static
will not only hassle the fuck outta you but also your neighbors for yards/meters
around
So now, the very same makers of this hassle have solved the issue ...for a price $30.60 and yes ....you need 2.
