Ok, im guilty of thread drift, but what lamps do you have?
They are all homemade olive oil lamps. Mason Jar (with a handle if you can find them), wick material, wire and olive oil.
Starting in the middle of a piece of wire, close the pliers over the wire and wrapped the wire around the head of a pair of pliers (large needle nose pliers have given the best results for me) to make a spiral that gets gradually larger in diameter with a large base for the wire and wick to sit on. Placed inside a pint or quart jar to size it up for the location to place a hook on the top of the jar rim. This holds everything in place.
Go back and bend part of the narrow portion (tightest wound part) of the spiral open, so you can insert a wick through the top part of the spiral. Re-adjust the hook on the rim of the glass jar if necessary.
We need to let the wick soak for 10 to 15 minutes before lighting it. To light, I lift the wick and spiral assembly out of the mason jar and light with a match, then lower it back into the jar catching the rim with the hook in the wire.
The last ones were made using coat hangers for the metal wire.
Probably the safest type oil lamp to use. The flame will only burn on the wick, if the wick burns down to the oil height the flame goes out.
When we used them regularly, we burned 2 to 4 ounces of olive oil per night per lamp and 3 lamps put out about 100 lumens. Placed in front of a mirror it helps light up a room fairly well.
Most of our light is now from our solar inverter battery storage.
