There was a thread a while back on a DIY candle lantern. Well Gargoyle posted a link to a site that sells LED tea lights. Well, I ordered 10 of them at $1.49 ea. They are submersible, use 2 cr 2032 batteries (included), are very bright and weigh .5 ounces. I put one inside of a McCormick spice jar as a diffuser connecteda piece of masons line and a tiny S-biner. The whole thing weighs 1.1 oz.2011-06-29 22.37.57.jpg
It will light up my bedroom enough to move around.
