Are ballasts designed for T12 lamps compatible with T8's and vice versa?
So basically, the only factor is lamp life? I have a customer with hundreds of fixtures and there are both type of ballasts intermingled everywhere. I have both lamps available and use the correct lamp when obvious but sometimes it isn't.
Gotta check each ballast's label.how could it not be obvious if the diameter of the lamp is different.t8=1", t12=1 1/2" ...just curious, please explain.

of course...guess im tired and read his op wrong. but, if customer has both lamps, and you read labels, how could you go wrong?
Because many times the only label the customer has is only on the covered up ballast.:roll:
Very common problem with customer doing their own maintenance when they have mixed type lamp fixtures, and not just with fluorescents, HID's are a big problem.

In a mixed-tube-type environment, even if tubes are installed, the chances are they don't match the ballast anyway.Quite often, I am faced with fixtures that have the lamps removed when I arrive. I know, I could take the fixture apart and check the ballast.
