I found these submersible non-flickering LED tealights - LINK - and thought that I would try them out as a supplement to candles in my UCO lanterm. They are rated for 48 hrs using two CR2032 batteries. I can stow one of these, two long-burning 6hour tea candles - LINK - and a cheap dollar store 2-3hour candle inside my UCO for a total of about 62 hours of light. This is opposed to carrying 5 cheap candles and getting 10-15 hours of light. They are basically the equivalent as those keychain squeeze lights...just a different enclosure.
Anyhow, I had the ideal of using these as a standalone light. I dug up a couple of spice bottles to use as diffusers and glued them inside the lids. They work pretty well; most of the light is directed off the end of the LED so they can be used outside the diffuser as a flashlight. If they were hung up the ground would be fairly well illuminated.
The photo shows the light a lot more evenly diffused than in person. I havenít added a bail yet, but it will most likely be in the form of a loop of cordage attached to the lid.
