"BMW says its laser system is 1000 times brighter than LED headlights but uses half the power." Yeah, that's bull, unless they're using some very creative definition of "brighter". LED headlights put out about as much light as do standard halogen incandescents, about 1000-1500 lumens per fixture. A million lumens? You'd be hard pressed to tell that apart from the sun. Also theoretically impossible, as LEDs are already at 10-25% maximum luminous efficacy.
