How do you attach a replacement ballast to a modern bucket light ballast bracket?
I want to get a better ballast for my bucket light, but the current one is welded on. If/when I remove it, there's not going to be any available ballast mounting for the new ballast.

Id leave the bracket with the original ballast and use new bracket for the new ballast

Where do I find a new bracket?

Some "everyday hardware" sort of bracket, not something made specially for lighting

I like the GE 201SA.  You can easily replace the ballast without having to worry about it being attached to a bracket.  The 201SA is great with LRUs (Line Replaceable Units)
