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.
Input Filter
Install in-line with the IEC input power cord of the ballast - reduces conducted emissions to electrical wiring
Max Conducted Emission Reduction: 45dB (0.45MHz - 30MHz)
Max Radiated Emission Reduction: 23dB (30MHz - 1000MHz)
Input Voltage: 120/240/277VAC
Frequency: 50/60Hz
Max Current: 15A
Output Filter
Install onto the output cord of the ballast - reduces RF levels of any digital/electronic power supply
Output filter comes with a "standard" male plug, an adapter is needed for HF ballasts
Max Conducted Emission: 25dB (0.45MHz - 30MHz)
Max Radiated Emission: 25dB (30MHz - 1000MHz)
Max Voltage: 600V
Max Current: 10A

yeah max volts is 600w
Good Luck
