I have 5 identical light fixtures (2-40 watt tubes with electronic ballast) in my garage, 3 of them broadcast AM strongly (strong engough to interfere with car radios in front of my house) 2 of are silent. I have compared the wiring of all of them and they are identical. On one of the noisy ones I redid all of the connections, made sure the ground lug on the case was bare metal and added a ground wire to the ballast. Result - no change.
If only one tube is installed the light makes no noise, with two it screams. The source of the noise seems to be the wires between the ballast and the tubes and the tubes themselves. I am getting ready to try an input filter (corcom type) and some beads on those wires. Any other suggestions? I'm really tired of having a dark shop. I can't just return them because I have had them almost a year now. (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) |

Check the supply voltage to the balast, if it is low due to poor connection (damn wire nuts) or whatever it will make all kinds of noise (RF).
We had a camera man who used dimmers on everything, he couldnt figure out why some lights caused his wireless to not work. . . |
