I have several tubes as well.
What should I do with all that?

Those replacment Transformers cost more than the new fixtures do.
I have put up the cheap sockets with the Curly lights. It takes three Curly lights to replace one Dual T-12 fixture. And then the Curly lights dont provide a real good work light.
The Bugs still like the light.
Anybody close that wants all that t-12 stuff?
