den haan make goood lamps. i have a perko oil lamp
light and when the burner failed i rigged it for led and made it so bright the mexican navy
requested me to dim it so they could sleep.
when it was just an oil lamp
i noticed a difference in the oils.
liquid paraffin is tolerable by even my sensitivities and allergies, whereas mineral oil and kerosene are hard on my lungs.
mineral oil an d liquid paraffin burn differently, liquid paraffin being more viscous than mineral oil.
i used to have a trawler lamp in my dinette.. one night i lit it, and friends unexpectedly arrived before i had adjusted the wick and trim for use...
the soot blacked the entire interior
. is still seen on my overhead..and so i clean yet from that, 5 yrs ago event.
other than that, even with my asthma and sensitivities to petroleum products exhaust
and fumes, i am able to use my interior
oil lamps when it is cold enough to warrant their use. i keep a port hole near the lamp open for ventilation, and am good with the heat and light.
awesome ambiance with my teakwood interior.
btw, i moved on board my first boat permanently in 1990, and have been using oil lamps since then. i prefer the patina maintained to keep lamps from looking like they were stolen from a french bordello.
shiny looks ok in a shiny production boat, but the oil lamps look so much nicer with a patina.
i have 1 beautiful yacht lamps with yacht globes over the chimneys in main saloon
, and in my masters cabin
, i have 2 used to be called miners lamps which in 1990s became known as yacht lamps by weems and plath.
many come with a thin film of varathane type protection, and when that is shined with brasso or other cleaners, it begins to peel off, and patina is patchy and ugly.
i leave mine alone except for dusting and inspections for functionality. mush prettier in my old wooden intertior boat with patina and antique appearance.
