A sodium vapor light isotropically emits 15W of light energy at 589 nm. If your pupil has a diameter of 4.5 mm, how many photons will pass into your eye every second from a distance of 12 m? 12 km? The threshold of seeing is about 5 photons/second. How far away can you see this 15W bulb? Note that the flux of a light source is the power absorbed/area.
