Another Paraffin User
I have that same beautiful paraffin oil (kerosene) lamp that rsn48 links to, but it's rather corroded now. Still, with that half-inch thick Fresnel lens (same as in lighthouses: sends a horizontal "ring" of concentrated light out), it's very visible. I light it and run it up my spreader halyard, and will continue to use it until I get around to getting up to my masthead and replacing the anchor light. A filled reservoir of slightly over 1/4 cup will burn in excess of 12 hours with fuel to spare, with proper wick trimming (not a tiny flame, but not huge and smoking). Yes it's old technology, and it works beautifully. It doesn't produce "soot" unless the wick is under-trimmed (huge).The paraffin (aka paraffin oil, kerosene or lamp oil) can be found in any chandelry. Weems & Plath is the brand West Marine carries, if I remember correctly.*** *** ***As to the LED of the original poster, a 30° arc for each bulb means 15 bulbs are needed to overlap each other slighty and get 360° coverage. Seems this is a crude design. A smaller, tighter central cluster of LEDs surrounded by some kind of diffusing lens I think would be more efficient, give a solid 360° ring of coverage, and use less power.LEDs are the wave of the future, but this one seems a little under-designed (though apparently rugged). They're drilling holes in a PVC end cap, shoving in LEDs and a voltage controller, and calling it an invention. No original parts, no manufacturing. I could cobble that together in my garage. If I pay someone else to do it, I don't want it to look as if I made it.Next, the same company will re-wire a box fan and sell them with great pride as wind generators.
