Sounds like your light fixture/ hood is not grounded. Shouldn’t have to run a separate wire for the ground. Assuming you have a three wire cable going to your lamp base, if not that’s a problem. There is probably a disconnect between your ground wire and the hood. Typical reasons for this problem are painted parts and or screws that do not conduct electricity. Sometimes anodized or some other coating that doesn’t conduct electricity is the problem. So if the lamp base is grounded and the base assembly is painted and its bolted to the hood sometimes just using a star washer or something to dig into the paint so it will make connection with the next piece of hardware will do the trick. Good troubleshooting skills finding that problem.

I run lumatek ballasts, quite a few of them. there is RF and other issues that span about 20-30ft from the ballasts. I'm not sure, but also suspect them of interfering with comcast cable internet. I have had persistant problems with comcast ever since I started using Lumatek ballasts. Comcast continues to shut me off, and I have to call in to get turned back on, they say I am causing a "lot of noise" in their network and they can see this from their infastructure monitoring software.
they pretty much know who is growing pot with digital ballasts. fortunately, there aint shit they can do about it in my state. I've even had the comcast guy tell me to be careful(he was cool.), they know. If I was anywhere but the west coast, I would never use a digital, and as soon as I have a good reason I will be going back to core&coil magnetic ballasts.
why bother paitning or covering your equipment, seriously?
throw that shit away and get some magnetics.
its not the electrical company you have to worry about.. its the cable guys or if you live somewhere the elect. company's is in cable...ive done cable for the past 10 years what we use was a seeker..this bad boy can point me right to you if there was anything wrong...heres a link most cable company's has something like this in each truck..fcc rules...
now a common thing we ran across from power was the neutral on the main burned up and the power for the house was looking for a ground witch usually was us... never fun grabbing hot cable... thats it hope this helps... oh on the link it tells you what fq we are looking at...
Ok, the title is pretty simple. If your running a digital ballast. There is a chance your producing RF noise. If your running a shitload of them. Good chance your keying a large signal and maybe causing problems with the person next door.
Here's a new material and idea that should cure the problem. Just wanted to post the link and info. I'm sure this idea and product with kill the signal. From what I've read. Looks to be a good idea.
Oh, before anyone saying digital ballast doesn't key up a signal, your wrong. I personally know one of the largest sales rep for one of the biggest light manufacturers in the country and he won't use one in his own personal garden. I won't go into details, but some of them do have their issues and some don't.
Hope this link helps those with any problems.
Take care,

I'm legal so I'm not worried about the cops in this instance or setting off a red flag.
I have wireless, cable TV, Trimeter, cordless phone/etc.....none of which seem affected by the ballasts.
I've seen poorly wired cable TV installs that put out more RF than these seem to...
great thread.

Just bought 2 solis tek 1000 w digital ballasts, which have cords which are warped in tin to eliminate any rf noise ...
Can't say enough about these ballasts.
Yo guys.
I have 6 digi's running @ present and will add more soon.
Any tips on how folks can test to see if they are tossing out RF without specific measuring devices?? Transistor radio? Phone? Some other device that will screw up in the presence of RF?
I used to work for the local Cable TV Co. We did the same kinda mobile tests. (Ok..this was in the 80's so the testing equip is probably different..)
any tips for the novice/layman on how to detect this interference?
thanks

The mags run at your line frequency, 60Hz if you're in North America. The electronic ballasts run much higher frequencies into the lamp. I haven't heard of and can't imagine coil-and-core ballasts interfering with Comcast cable.So magnetic ballasts dont produce the RF strong enough to interfere with the cable? I had a visit today...
Killed all ballasts while he was putting a new connector on and he thought that was it..
Obviously I dont want any more surprise visits
