The hood won't go black as 12uF is not that much of a capacitance and is an equivalent of 220 Ohms load except it is purely capacitive, and the current itself will be 1/2 A.
And this is one of those cases where "the size doesn't matter" Icon_smile
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
