C.A.P. Nextgen ballast Question

Has anyone used these ballast’s before? Was wondering if they have any RF interference at all? I need to know before firing up cause my girlfriend works in her office right above my room.i have 4 nextgen 600/400w and 4 nextgen 1000w And 1 ipower 1000w and 1 Gavita pro E-series Flex 6/750.hopig someone who has hands on exsperience with these nextgen ballast’s.thanks guys hope to here from you soon

Really nobody has used these?

It's old tech for sure, CAP went out of business in 2013 and hydrofarm picked up their old inventory.

Used those many times over without any issues.
I haven't seen nextgen ballasts since 2012 was the last time I used mine.
Same 400/600 no interference from these many years of using.
