The SI unit of EMF (electromotive force) in a direct current circuit is Volts. The circuits current is measured in ampere's
I don't believe that there is such a thing as an 'ampere per lumen'. An ampere is the SI unit of current, whereas the lumen is the SI photometric unit for luminous flux. There is no direct relationship between the two.
Ampere (A)
The ampere (A) is the base unit for current in the SI system.
Yes, the ampere is an SI base unit, one of the seven, and equals the passage of a Coulomb of charge per second. Its official definition has to do with force between current carrying wires though.
The Ampere (or Amp.) for large things such as a toaster, microwave or refrigerator. Most electronic devices use current measured in milliamperes (or miliamps) which measures thousanth (1/1000) of an ampere.
The SI unit of electric current is the ampere. While it is an SI base unit, it can also be considered to be a combined unit, coulombs per second.
The SI unit of electric current is the Ampere.

That's the electrical current, also known simply as "current". The SI unit for current is the ampere.
