The last time I dealt with an 8' T12 to T8 conversion, the technology was still relatively new. We swapped the ballasts and bulbs and left the fixtures intact. Those ballasts lasted a year or two before the vast majority of them failed. As they failed, we ended up putting the old T12 bulbs and ballasts back.
Since then, I've seen a great many 8' T12 ugrades where they modify the fixture to accept two rows of 4' T8's instead of 8' lamps. I always assumed this was because the 8' T8 technology was so terrible (based on my experience) but never had to deal with this myself.
Now I've got a building once again that has a great many 8' T12 fixtures they want to upgrade to T8. Is there any reason to do anything other than a bulb/ballast swap, to 8' T8s and electronic ballasts? T8 technology in general has come a LONG way since my last conversion.
