If you already own said lantern and consumables just sitting around, sure.
Otherwise ... gas lanterns are watts per lumen as opposed to the more familiar inverse for electric light sources. Some very hasty math using the Coleman Dual Fuel:
At $3/gallon for gasoline it will cost you ~$0.94 to run the lantern for 5 hours or ~$0.19/hr. Likely cheaper than premium, retail-priced primary cells - ala CR123As purchased at the local Worst Buy - but I suspect most other use cases to be significantly cheaper.

2.5 pints of gas = 0.3125 gallon * 33,000Wh/gallon = 10,312.5 Wh / 5 hours = 2062.5W / 800 lm = 2.578 W/lumenAt $3/gallon for gasoline it will cost you ~$0.94 to run the lantern for 5 hours or ~$0.19/hr.

If you line a jar with tin foil you can just capture the sunlight during the day & open it at night to let the light out.
Just make sure you have the shiny side facing inwards. If you use a really big jar It'll shine longer.

Many years ago a friend was working with one of the dullest knives in the drawer. My friend sent dull knife to the mechanical room for a bucket of steam. He told him they needed to clean some things. Off the guy went.

BTW go to dollar store buy 5 solar patio lights set them up so one was at top it shines on the day light sensor of the next light do all the same way. As one dims the next one thinks it dark and it lights up. A course charge them uo with sun at first. I dismantle them to make it more compact

WTH is this nonsense?! So, they're apparently trapped in a room.... that has giant glass windows in the wall and doors.... and they use a laser to melt through the metal lower part of the door.
The incident angle of the laser when she activated it meant that it would not have gone towards the other mirror at all....
And based on their position in the room, when she rotated the mirrors, the laser beam would've swept around the room and cut off her friend at the ankles.
Who writes this stuff???

You ID'ed it in those four words. Just laugh at the absurdity.
The cheapest way to see things in darkness is to teach a cat to speak and just walk behind him.

I'm not sure the human mind is capable of processing the speed with which a cat would likely narrate the experience nor their extreme ADHD.

And since cats are a-holes they would deliberately lead you to crash into stuff and trip over things...

Trust me when I state this psychotic a-hole is the last member of the family I'd trust to lead me through the dark.
