cold cathode light totally interferes with my IR remote control!!! Answered

I have a view-box for looking at negatives that uses cold cathode tubes as the light source--whenever this light is on my IR remote control for my wifi radio does not work--i have isolated it to EMI from the light not the light itself. when i covered the peripheral area where the wires and 2 ballasts are with 2 layers of heavy duty aluminum foil it drastically reduced the interference. i cant practically use the foil. Does anyone think ferrite snap cores from radio shack will work? if so-- where and how many should i put?--really need help--i have little electronic experience--

Worth a try, on the inputs AND outputs.

Did you ground the foil ?
