As a prepper and being fond of the UCO candle lantern I’ve had for many years, I wanted to utilize it to make it affordable to use regularly, and very often really. As you may know some of the UCO candle lanterns, mainly the older design, require a proprietary candle that they sell in 3 packs, which runs about 5 bucks a pack. That’s just too much money to pay for 3 candles that burn for what, 10 hours total maybe? when the tealights I found on Amazon (purchased in bulk at about .12 cents apiece) will burn for about 5-6 hours each and I can stack 5 of them in my UCO lantern with this aluminum can modification!
