Tired of dealing with balky fluorescent tubes and old magnetic ballasts ($$$) in my basement, I bit the bullet and bought 2 LED 4-footers, removed the dead ballast and turned on the lights. Dim bulbs. Apparently there are 3 kinds of LED tubes. Mine needed a T8 electric ballast. $16.95 later from my local electrical supply house, about 10 minutes labor and voila - let there be light. And there was. Instantly. I can recommend the change and you can do it yourself. Remember to turn off the breaker as there may be some current left in the wires even with the switch off. Don't ask me how I know. Total cost - less than $40.00.
