I know I'm being lazy and could easily look this up on wikipedia or comicvine, but I'd like to hear from the realmsers what this storyline was about. I know NOTHING about it.

For instance, is it set in the pre-52 or Nu-52 timeline? Is it part of Blackest Night/Brightest Day? Or something completely different? Which characters were major players in the event? Is it (the comic book series) even worth reading? Thanks.

pre Nu52. essentially starts with Green Lantern: Rebirth, then carries into Green Lantern: Sinestro Corps War, then finished with Green Lantern: Blackest Night. Great trilogy

There's a war. There may or may not be light involved.

That's as much as I was able to gather.

There's some people who believe in halogen. Some that prefer fluorescent. And others prefer incandescent.

They battle for supremacy, but then unite together against JJ Abrams and his Legion of Lens Flares.

Yea, it is pretty much the introduction to all the new colored corps. It started with Sinestro COrps, then Blue Lanterns, then Orange Lanterns, then Red Lanterns, and so fourth. It was just showcasing all the emotions and introducing their leaders and the other entities. Fantastic read all the way through.

It is one of the best things I have ever read, and I read quite a bit. It was mainly in the green lantern books from 2005 until blackest night/brightest day, so it focuses on Hal. But all of the lanterns are heavily involved. Check it out.

Was this all undone by nu52 or has it been blended in somehow? (I must confess I quit reading DC with the latest reboot.)

It was published in Pre-Nu52 (which I guess is technically Post-Crisis?) but even in Nu52 continuity, "The War of the Light" happened.

I'm generally a Green purist and don't think the major players in the DCU needed power rings to be any more significant.

Apparently someone at DC decided there should be rings for all colors of the rainbow. Geoff Johns had the neat idea that the Guardians settled on Green since it's the most stable in the middle of the color spectrum (ROY G BIV).

I don't know who in continuity started handing out rings or if the other colored lantern corps were sitting around in different corners of the universe, much like ancient civilizations were growing independently on Earth thousands of years ago. And I think there was a prophecy about the Black Light coming about for Armageddon after the War, and then the White Light fixed everything, possibly some biblical metaphor, I dunno.

I'm sure some Metro-Modern Lantern fan will come along and give you a better idea of what happened, but that's all I know...

... and for as much as I'm anti-colored-lanterns, the Green Lantern Animated Series with Razer and Aya was pretty damn good.

"All right, see, you also the savior of their race, like me, okay? So you gotta buy all the stuff in this catalog, then I get points, then so do they get points, and you get points too so they can get that Gorgotron killed, and somehow, someone gets a Ferrari."

That's how Meatwad would explain it. He's more of an authority than I.

Nope, for the most part the Nu52 didn't touch the Green Lantern comic book. They only changed him in the Justice League comic. Once Geoff left though it has gotten kind of bad. It could be it's not bad but from where it was it just has gone down hill.

Blended in. It all happened, but the particulars where non-Green Lantern DCU characters were involved (ie, Green Arrow, deputy lanterns, Cyborg Superman) are subject to change.

I thought the whole Geoff Johns run was quite good, though the best parts were everything through Sinestro Corps War. After that, it felt like everything else was going through the motions, like Brubaker's Captain America run post-death of Steve Rogers, only Blackest Night stuff was more interesting than the return of Steve Rogers.

Other Lantern types are either discovered or retconned into being Lantern types. It gave us an "emotional spectrum".
Red for Rage, Orange for Greed, Yellow for Fear (causing it), Green for Willpower (an emotion!), Blue for Hope, Indigo for Compassion, and Purple for Passion.

There was fighting. Mostly the Sinestro (Yellow) Lantern Corp and the Red Lanterns. Stuff happens, really vague on it, and such. Then the Black Lanterns show up, led by the Black Hand. Rings went to the rotting corpses (and non-remains, like a few characters who I think were even disintegrated), they came back as zombie lanterns who fed off emotional energy.

Anyway, good guys win, a White Lantern gets found, it's the power of life or some such. There's something about different Lanterns combining their power. Captain Planet shows up. A few characters get resurrected. A few other characters become weirdly elemental for like an issue.

My memory isn't great but I think......

It all starts with the Montague's and Capulet's, see they don't like each other but they are forced for the greater good of mankind to join together and take the one ring and throw it into the fires of Endor while being chased by Daleks. Some twists and turns here and there, that part with Keyzer Soze, and will smith was in there somewhere. It all ended with that huge battle between Scotland and the Klingons and then Jason voorhees and milla jovavich get married and everyone was happy

O and Bruce Willis was dead the whole time.....


But like I said my memory is a bit hazy.

The simple answer is that the War of Light is the period in Pre52 DC Green Lantern books immediately following (arguably including) The Sinestro Corp War and before Blackest Night, focusing on the introduction of the founding of the different color Corps and explaining the emotional spectrum.

A more satisfying answer to the question comes from quoting Ganthet in the Sinestro Corps War (Green Lantern #25 pre nu52 reboot)

He first gives an explanation of the emotional spectrum and how Sinestro's Corps indicates the other Corps will begin to form as well.

"Seven Corps will be born."
"Seven Corps will shine their light brightly."
"Seven Corps will be at war."
"It is foretold that as the emotional spectrum glows brighter and the War of Light ignites in full force the skies over every world will darken."
"The hiss of the shadows will announce to us that our time is over."
"Then the Blackest Night will descend upon us all. Without prejudice or mercy. Without reason."
"The Seven Corps will fall."
"As will the Universe."
"Back to a place devoid of light. Of emotion. And of life."

After the Sinestro Corp appeared the introduction of the other Corps was kinda sprinted through to get to the Blackest Night event and there were some missed opportunities IMO. Namely that there was no actual War of Light, just a few skirmishes before the Black Lantern Rings showed up.
