Ballast interference

One guy had a thread on how his digital ballast almost got him in trouble. The ballast was too close to his cable box and the cable guy came out. The ballast fed back into the cable and f'uckeded up everyone's cable. His wife chopped down all his plants or something too.

He could have had cops all over him.

I posted about this not to long ago aperantly take a handheld radio and put it on am and test. I put my phone next to mine while it was on text and WiFi good took a walkie to it no feed back.

Some one told me to coil any extra cord rather than figure 8. Keeps the field smaller

I am curious on this same issue with a lot of these LED's
It's interesting that they will make the camera on your phone go all whack

I have had the RFI squad out over digital ballasts causing ingress on cable lines. Shetty phone and wifi signals, lines and bars on TV's etc. Just your good old RFI and digital grow problems.

Aluminum foil is your friend.

Like just wrap it in foil?

It's the long azz power cord from the ballast to the hood at is the issue and transmitting the RFI.

I wrapped it in 3 layers of smooth as you can keep it foil and RFI went away by 80-90%. Crumpled it all up and the TV's got lines again and all the other sheet.

If OCD involved use a metal trash can with a fan inside and 0 RFI is going any where.

High frequency ballasts, especially cheaply made ones, are generally the source of problems with RFI.

Low frequency ballasts like magnetic ballasts and low frequency square wave drivers for 315W CMH lights will minimize this issue.

LED lights are driven by DC current, also not a source of RFI.

Gonna have to say not cheap ones do that too. Multiple ones I pulled out the closet.

Oh I see the steel trash can you spoke of. One last the chief concern here is power cable not the actual ballast right? Heat being a concern with the ballast it's self.

My digi's run pretty cool and the 1100cfm exhuast cools them .

Correct it is the ballast cable going to the hood. I assume the shielding on some are sub par. hmpf makes me think I should put up a different hood to check that.. I have raptors up atm.
