I put 397 then just read the question:

"Calculate the currentin the leads connected to the lamp"

This is suggesting your supposed to use 0.2V (12V output minus 11.8V p.d. across lamp).

And then "Calculate the power dissipated in the leads"

serious!

Nah, i bet using the 11.8V is 1/2 marks on each question for using a suitable method/equation.

That brings me down to about 80, plus any silly mistakes in calculations.
