Non-military Use
Today, searchlights are used in advertising, fairs, festivals and other public events. Their use was once common for movie premieres; the waving searchlight beams can still be seen as a design element in the logo of the 20th Century Fox movie studio, and Fox television network. The world's most powerful searchlight today beams from the top of the pyramid-shaped Luxor Hotel in Las Vegas. The beam concentrates about 25,000,000 lumens from 39 7kW xenon lamps into its beam of about 40,000,000,000 candela. The brightness emanating from the Luxor lamp room is about twice that which emanates from an equal area of the sun's surface (about 95,000,000 cd/ft2 versus 45,000,000 cd/ft2).
