Got another commercial 120-277v F40T12 rapid start ballast.
This time I put it in a 4 foot T5 fixture.
It works. The tube are doing about 44w each.
The old ballasts we only doing about 21w each. The old ballast was intended for 3 or 4 foot T5 Tubes.
They are not horrible ballasts aside from low output, they run about a 0.8pf which is really good for 120v only ballasts.
