Luxor Hotel & Casino

This guide to the Luxor in Las Vegas starts with the desert moths that swirl by the thousands into the pyramid's sky beam, one of the brightest single shafts of light on earth, switched on when the resort opened in October 1993. It traces the thirty-nine xenon lamps behind the beam and just how far away pilots can spot it. Look straight up after dark to catch the moths gathering before anything else arrives.
