Magnetic ballasts can last 20-30 years or even longer. Depends completely on how hot it was run. Put a good fan on a magnetic ballast (even a cheap one) and always run bulbs that are within reason age wise and it can potentially outlast your lifetime.Wow! Scary story. Thank god you were home bro. How old is too old for ballasts?!!
Electronic ballasts still can't match that longevity yet, 10 years is still good for those, but they have gotten a lot better than the early days and will catch up eventually.
