I just finished a job where I installed 10 new T-5 fluorescent 6 lamp fixture with ho electronic ballast. The AM radio signal is covered up with static so bad it is almost impossible to listen to.Does anyone have a solution to this problem Thanks Barry

 

Other than a radio with a coax input and an antenna far far away, this one is going to be hard to beat. You could filter the AC line going to the lamp fixtures, but as with all AC projects there are some inherent dangers.

Look up PI filters on Wikipedia.
