This is a homebrew that took about 20 minutes to do-
Just before we left for a camping trip, I realized I didn't have any chemical "snap lights" for my daughter to use as a night light- so into the workshop I went....
It's built inside a Fuji-film canister using a PC Cmos battery holder and coincell, the LED has a small section of hotglue stick pressed on it to help diffuse the light. I have no idea how long it will last, but it made it through 2 nights without any sign of dimming- costs nearly zero to make, and works well.
