Reading lamp that is easy on the eyes. I have used candles, headlamps, and at least one portable camping light to provide lighting for reading and writing at night in camp. A drawback of all those tools is the glare of the lamp. By contrast, this simple system is easy on the eyes. It is a gallon milk jug filled with water with a headlamp pointing into the water.
Camping tip..Keep your cooler cold without the slushy water. Fill a gallon or half gallon jug with water. add 1/4 cup table salt to the gallon or 1/8 cup to a half gallon . leave an inch of room at the top of the jug for expansion and freeze. place in your cooler instead of an ice bag,,
