Well, the north star is not particularly bright in the scheme of visible stars in the night sky. It ranks somewhere near 50th for brightness. But for the question if the brightest "light" on Earth, it depends on your scale. The brightest city is most likely LA. The brightest city section is reported to be the Las Vegas strip . But the brightest individual light? That goes to the Luxor Sky Beam atop the iconic pyramid. Answer from rxneutrino on reddit.com

r/askscience on Reddit: What is the brightest light on Earth?
August 7, 2017 -
Hello reddit, I just saw another space post by someone on the ISS. Some areas on earth at night are obviously brighter than others due to being clusters of lights in cities. I now wonder, what light on Earth is the most noticeable from space. It's almost like looking for the North star, except on Earth.

I'm not sure exactly what kind of answer you're looking for, but if you define "bright" as the maximum photon flux through an observer's position in space, the brightest thing earth has would definitely be a laser. The trick with this is, unlike city lights, lasers are extremely directional, so you really have to know where to point the laser. But, if you know where/when someone will be looking toward earth and you want them to see a super bright light, use a laser! I'm not sure what the brightest lasers on earth are, but you could definitely blind someone on the ISS, and you could easily be seen many many lightyears away, assuming you know where the observer will be that many years in advance!

October 16, 2023 - The BOAT lasted approximately seven minutes and contained more energy than if the entire sun’s mass was converted into energy at once. It slightly disturbed the Earth’s ionosphere, despite being unimaginably distant at 2.4 billion light years from Earth. The BOAT's true brightness is not fully measured because it saturated the detectors of almost all gamma-ray instruments in space.

April 9, 2008 - “My astrophysicist friends tell me that near a gamma-ray burst, they surmised that the [light] intensity probably gets to 1020 watts per square centimetre during the explosion,” Ditmire told New Scientist. Light from the Texas Petawatt laser can reach about 100 times that level, he says. “For the briefest instant, over a very small volume, we’ll have the brightest light in the universe.”

Answer (1 of 2): That kind of depends on what you call “world” and “light”. I define brightness as watts per steradian, so it doesn’t change brightness as a function of how far you are from it.
