    So this thread got me thinking. Would the lux at 1/4 mile of say the new deft or a maxabeam be much higher in space?

    Yes, no air or particulates. And LEDs get brighter as temps drop into inhumane levels.

    A just-published three-year study from a gamma ray array in Tibet captured output from the Crab Nebula in which individual photons had the kinetic energy of a flying bumblebee - the most powerful light ever seen on planet Earth.
