pretty interesting find there

I have seen split ballasts for fluorescent tubes and large 600-1000W HID lamps

but I cant say I have seen a split ballast for something like a 80W mercury lamp

I wonder if a single 1 of these chokes would run a 2ft 40W tube on 120V mains?

My other hobby is buses, especially the Routemaster
