NEW ORLEANS - In every way imaginable, both literally and figuratively, Super Bowl XLVII was "lights out."

The Baltimore Ravens survived a 34-minute third-quarter power outage and a furious comeback attempt by the San Francisco 49ers on Sunday to claim their second NFL championship, winning 34-31 in one of history's most memorable Super Bowls.

Thanks to a postseason-record 108-yard kickoff return for a touchdown by Jacoby Jones to start the second half, the Ravens led 28-6 when the main power went out in the Mercedes-Benz Superdome with 13:28 left in the third quarter.

More than a half-hour later, the restoration of power seemed to re-energize the 49ers. They outscored the Ravens 23-3 over a span of 12:23 to cut the lead to 31-29 with 9:57 left in the game.

The Ravens responded with another field goal, but the Niners had the ball at the Baltimore 5 with two minutes left and a chance to win the franchise's sixth Super Bowl.

But three incomplete passes by Colin Kaepernick - all targeted toward Michael Crabtree, and one that came with controversy - ended the 49ers' bid, handing the Ravens and Ray Lewis their second Super Bowl ring since the franchise moved from Cleveland to Baltimore.

For the Ravens, quarterback Joe Flacco was masterful behind center and won game MVP honors. Lewis ended his 17-year career with his second Super Bowl victory. Superb safety Ed Reed made yet another postseason interception and numerous big plays.

And, of course, there was the power interruption. As officials scrambled to restore the lighting and scoreboard functionality in the Superdome, coaches didn't know if on-field and pressbox communication systems were going to work.

At one point, Ravens coach John Harbaugh argued with officials over what would and would not be allowed. His brother, Jim Harbaugh, led the 49ers to the Super Bowl, marking the first time siblings have coached against each other in the game.
