Luke was not using the dark side in his duel.
You're seeing it too literally.
Because at the end of the duel Luke realised the darkness within himself (when he was looking at Vader missing hand, then looking at his own) and accepting it. Thus allowing the darkness to wash over him, and not longer having any power over him.
Making Luke incorruptible by The Senate.
That doesn't prove your point.
