If you’re looking for a compact rust-proof, wind-proof lantern, UCO Candle Lanterns has created a micro candle lantern.
It lasts several hours after inserting a tea light, which makes it one of the most inexpensive lanterns as well. If you’re hiking or camping and want to pack light, this micro lantern collapses down to 2 ½ inches.
The base has enough room to store a spare tea light too! Tea lights are a very economical alternative to batteries and the candle powered lantern is compatible with leave no trace ethics.
I think a couple of these mini lanterns would be handy just to have around the house in case of a blackout. Why does it seem like the batteries run out of flashlights just when you need them? Another bonus is the candle lanterns would supply warmth as well as light.
