IMO nothing beats a Coleman 237 Lantern. They are a 500-550 candle power single mantle lantern that can run on just about any fuel....kerosene, white/coleman gas, unleaded, diesel, etc. Its primarily labeled as a kerosense lantern, but because its the largest generator coleman ever put on one of their lanterns, it'll burn just about any liquid fuel you can throw at it. I have 3 of them and mainly run kerosene in them. They were made from the '40s-'60s and they are built to last. You can find them from time to time on ebay, but expect to shell out well over $100 for one in fair-to-good condition.
The best way to describe the light output from one of these babies is that it will light up your campsite plus the two adjacent campsites.
Coleman still makes a single mantle Kerosene lantern rated at 500 cp...its the Coleman 639C and sells for $80-$90 new. These can only run Kerosene and white gas (or a mix of the two) but nothing beyond that due to its smaller generator when compared to the 237. When compared to a 237, you can notice that its got a bit less light output....though its still a strong, bright light.
If you're a white/coleman gas only type person, then the Coleman 236 is the 237s sister lantern that only is capable of burning white/coleman gas....its rated at 500 CP, but again doesn't quite match the light output of the 237 in a side by side comparison. Again made from the 40s-60s, Coleman no longer makes a single mantle 500 CP white gas only lantern
here is a nice video showing 9 of them burning at once....note because they are kerosene and give off no carbon monoxide, you can burn them indoors too (if you don't mind the smell

):
