I am designing a high-altitude weather balloon for a college project. The balloon may fly at night, which means that, per FAA regulations, I need a light that is visible for 5 miles.

Does anyone know how to calculate this? Or knows some cheap and lightweight LED lights that work for this application?

    $\begingroup$ Search on AircraftSpruce.com for anti-collision lights. They aren’t cheap, starting around $500. Since it is just a project, you won’t need a TSO version. This one is lightweight and says "Exceeding all TSO intensity requirements" aircraftspruce.com/catalog/elpages/… $\endgroup$ – JScarry Mar 16 at 14:09
  • $\begingroup$ hmmm $500 is our entire budget haha, but this has given me a good place to start! Thank you $\endgroup$ – Timothy Barrett Mar 17 at 17:23
