The Stratosphere in Las Vegas is, like everything else, a hotel and casino, but it also has a tall Space Needle-like tower that tourists can ascend and see the city. The view really is quite impressive. If you can see the strange streak-looking light three-quarters of the way into the picture from the left, you’re looking at the light from the Luxor hotel–a pyramid-shaped casino in the middle of the city. The light is the brightest beam in the world, at 42.3 billion candela (lumens). At 315 kilowatts, that’s an expensive light bill!
