[DC] How is Lex Luthor a threat to Superman?

Superman is strong enough to fight Green Lanterns, wielders of what is literally the strongest weapon in existence. Yet somehow Lex has managed to build a suit that can take him in a fight. How was he able to do this while Earth remains so far behind the tech curve of the galaxy?

I'd say it comes down to 2 reasons. Firstly Supes knows that Lex is just a human under the suit so he's going to be pulling his punches making sure he doesn't actually hurt Lex. And secondly Lex's armor is powered by Kryptonite and fires Kryptonite energy blasts. Just by being in the fight he's weakening Superman.
