I finished up just now, real easy after I did the first one. I pulled 6 ballasts 5 were leaking and going bad.
It cost me $120 to rewire the fixtures and replace the bulbs, it would have cost me $118 to replace 5 ballasts and it looked like some of the fluorescent tubes were on their last leg.
I have a bunch of fluorescent fixtures in the house, the ballasts are 16 years old, when they go out I am swapping them all over to LED.
There are few shadows in my shop now.
