i tried 2 newer lumatek 600s with shielded cables and they still fucked up my tv reception across the house.
also, they blew 3 hortilux bulbs in the first month, so....i sent everything back (these aren't compatible but i was never told that of course)
that's just my experience with them, im sure plenty of folks out there are having no problems
The RFI thing is not the real problem, Digi's eat bulbs and fail at will. I have tried 4 or 5 digis and all of them are in the bone yard, I'm still using a 12 year old mag ballast, always there when I needed it.
I guess, if it ain't broke, don't fix it! Bought a1000 watt Mag today...now i gots to get a 240 hook up for it!
Are you sure it's not multi-tap? Most new ballasts are.
The hum on a mag ballast can be taken care of just as easily, if not easier, than the RF interference from a digi, and it really isn't that prevalent in any event. I've run 1kw grows with people regularly passing within 5 ft of the grow, and the hum was no issue at all.
And are you saying digi manufacturers have developed faster than light technology?! Light speed is light speed man
