I have 4ft flouresent lights in both bathrooms I had to change everything
in the one bath my question is why do I have to change everything transfomer and bulbs.I should not have to change the transformer every time or do I? Thanks in advance for the help!!
No, you should not have to change the transformer (ballast) every time you change bulbs. Could it be possible though, that the wrong bulbs were installed, thus causing the transformer to burn out?
Make sure the bulb wattage is not higher than what the transformer is rated for.
