Output of the Sun: How many Lumens?

[CMAG]

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.

And if you want bright cosmic objects, look into pulsars. Our sun is 865,000 miles in diameter and only lights the majority of the solar system, which is ten light hours across. The Crab Nebula pulsar is only ten miles in diameter and lights a dust cloud 23 light years across.

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.

How many lumens does the sun produce?

Easy, all of them. :nana:

Our sun is modestly below average in output compared to other stars; the aforementioned Crab Nebula Pulsar is ~100,000 times brighter in its current state, however when it went off in 1054 AD, it was bright enough to be visible in the daytime sky for 23 days.

Hate to say this, but all individual light photons have the same amount of energy, regardless of source or distance.
