Use the old fashioned kerosine lamps, with the new lamp oils they burn clean and give plenty of light.
I have 8 of them in the house for when the power goes out (as in every winter snow storm, summer lighting storm, or forest fire) and they are plenty of light to cook or read.
I use FEUER model 276, they are light weight, tough, and easy to fill or clean.
I don’t think they are any bigger than your old propane style lights.
Thanks... I’ll look into it.
