    The brightest light in the world is a laser pulse emitted by the Texas Petawatt Laser in Austin, TX.  It’s laser pulses emit more than 1 petawatt of power, which is equivalent to a million billion watts.  Although incredibly powerful, these laser pulses are incredibly brief.  

    The brightest continuous light beam is the incredibly powerful light on top of the Luxor Pyramid in Las Vegas, which can be seen from 275 miles away.
