I went on a call today to replace some ballats in some fixtures at a retail store.
These were 2 x 4 lay in's. (They set in the grid of a dropped ceiling).
The ballast I am given to replace is "REL-4P32-RH-TP". One ballast, operates all 4 bulbs. The bulbs are T8's.
I get to one paticular fixture and notice it has 2 ballasts. "R-2S40-1-TP". 1 ballast for 2 bulbs of the fixture. the store owner was using T8 type bulbs in this fixture when the ballast calls for T12 type. Owner also complaining of bulbs not lasting long, flickering alot, ect.
Since the owner was supplying the ballasts, all I could do to get it to work correctly was to rewire the tombstones according to the diagram on the ballast.
Would installing T8 type bulbs in a fixture where the ballast calls for T12 type bulbs, ruin bulbs, ruin ballasts. Both?
