Stormlykta Optimus 200 P

I'm burning a mantel and lights the Optimus 200 P kerosene pressure lamp. I have rediscovered something that we take for granted. Sometimes proper lighting is needed - when candles and flashlights are not enough. For example, when you establish a command center and need to look at maps, take notes, read plans and instructions and more. Especially during the dark time of year. In addition, power generators are noisy and can be very disturbing when placed close to the staff tents. A kerosene lamp / Tilley storm lantern provides a bright light. But how many remember how to use these or have even used a kerosene pressure lamp.
