300 Watt CFl's

Hey all........just wondering if anybody has had any luck with these cfl's, they now come in 300 watt & 2 types , 1 for veg @6400k & 1 for flower @2700k or so they say, they say they consume half the power, which is a huge bonus, but instead of listening to the makers & sellers, ask the people who know , any input appreiated
