I have several Coleman lanterns, and a couple of led lamps for nightlights. If you really want to light things up try a Petromax lantern. They were designed to burn any flamable liquid, put out 500cp and are built like a tank. They can be a bit tricky to adjust but once you get it right they are the brightest lamp I have ever seen. If you actually read the instructions adjusting them is no problem, otherwise you can spend hours trying to light them without success.
I paid over $100 for my first one. The second one was a gift, but cost about $50. Shop around for a good price. It is worth having at least one of these around when the lights go out.
The only real drawback is that I would never consider lighting one of these indoors. They use what is basically a built in blowtorch to get things started. Once started they run great.
