I found a brand new German-made oil/kerosene lamp at a yard sale a couple of years ago. I have used it a few times. This is about how bright it gets with lamp oil without producing noticeable soot. With a bigger flame, you'll keep the bugs away and get black lungs. The distance to the wall is about 1.5 feet. You can easily traipse through the woods during a downpour at night and fall into your favorite fishing hole. As you can see in the picture I wrapped the globe lifting lever with friction tape so it won't wear off the paint. Please note I lit the lamp for you guys. At Casa De Vava we keep the light on for you.
