Please note, the study did not mention lamp oil, which burns cleaner than kerosene. It’s also easier on your wicks. And Aladdin lamps are the way to go...no pumping and very little noise (man, I hate the sound of a Coleman lamp!)
“lamp oil, which burns cleaner than kerosene”
yup, but price and utility lead me to kerosene as a backup. multiple uses, though the odor is annoying.
I suspect the study is referring to the old-fashioned sort of lamp. I also suspect that Aladdin lamps (I've got some as backups to my Colemans, which are backups to my LED lanterns----(I'm from hurricane country....backups were necessary....and the situation is WORSE up here in the "great northwest" of Washington state)) put out MUCH less carbon black than regular wick-only type lamps.
