However the cool tube company is all like " I dont see how that could happened" Im like dude the screw attached to the metal, the same metal that the green "nuetral wire" is screwed to, and when white or black green THE BALLAST WILL FAIL!! some people are takers i guess.... Either way i have a new ballast coming and need to buy another cool tube and 2 plug in noice blockers for the ballast so they wont send out so much frequency
