There are two entirely different (and incompatable) lamps that are 3 feet
long, 1 inch diameter, with "medium bi-pin" ends. F30T8 lamps are intended
for a preheat ballast and they only have a rated life of 7500 hours. They
are basically the same technology as the old T12's. I think they might
actually be interchangable with F30T12's. F25T8 lamps operate at a lower
current and a much higher voltage; they are usually used with electronic
ballasts. They have a rated life of 20000 hours and produce about the same
amount of light as the F30T8's (but use less electricity).
