ATP and NADPH are PRODUCED in the light dependent stage. Do you mean light independent?
Yeah so they are produced...... although the question was 'Why are ATP and NADPH necessary in the light dependant stage', I agree with where you are coming from.
They are produced during photolysis aren't they when replacing the electrons lost from the chlorophyll producing the NADPH?!

NADPH is produced from NADP, a cofactor, H+ ions from photolysis and electrons from being passed through photosystem I in cyclic photophosphorylation. ATP is produced from chemiosmosis by pumping H+ ions into the stroma across the thylakoid membrane from the thylakoid space using energy released from the initial electron being passed down the electron transport chain.
