What.

And as far as I am aware, any LED lantern I have seen will not produce as much light outwards as a gas coleman lantern.

I would consider the sun the most efficient source of light for us. That's a big run on sentence by the way.

That's creative advertising that's what that is. The most efficient light source would depend on what light level you were looking for and possibly other enviromental factors, not to mention output duration. There are lots of light technologies.
