I retried my T12 ballast to T8 tube experiment again.
Got a free damaged 40w T12 high output rapid start fixture, with no tubes, only about 2 years old so I Figured the ballast was probably good.
I decided to replace my very lame 25w producing T8 ballast with the T12 ballast just to see what would happen.
This time it worked, because the ballast wasn't dead.
Only problem is the fixture is pumping out 60 watts per tube.
They put off a lot of light, they look like 1 inch thick T5 high output tubes, so bright you don't want to lock your eyes on them.
I'm sure that this will shorten their life a bit.
Then tried some 40w high output T12 tubes left over from my T8 LED upgrade.
Even the T12 tubes are running 55w. The T12 will probably last a little longer than the T8 tubes.
Both the T8 and T12 tubes have the same bi-pin base.
