Could you give me some more details on that, like what ballasts you
used and where you got them? Was it relatively cheap and easy to swap
them out? I'm assuming it would be cheaper than spending the $150 on
the high-bay fixtures....

I just swapped in electronic ballasts, new sockets, and new T-8 bulbs into
some T-12 fixtures for about around $25 each fixture. It would have cost
about $5 to $10 more to get new fixtures, but I saw no reason to throw out
all that steel.
