It is (auto?)transformer ballast - like HX

You can tell by that the line current is higher than lamp current which means that it is a step up transformer. The 4 connections are a hint too though there are ballasts that connect to the N too and are not transformers

it look like an auto transfomer. not only that it also look like it was intended to sold on american market
becase it UL approve ballast. does any one know how old that ballast is?

well this is going in my american fluorescent F30 fixture that i found badly rusted. going to sand it down and repaint it.

I found how to view the picture.
The ballast have an european style, and is probably an export ballast to the US.
I compared it to an Eltam magnetic choke ballast for 36W T8, and as this ballast have four wires instead of two, i think that this is truly an autotransformer ballast and not a choke ballast.
