I don't know what the original post is since it was deleted but I have a glow lite that serves as a night light. It is about as strong as a photographic darkroom light and hardly uses any power.. It is 110V though
I removed the link because I actually researched it. Someone took a bottle of Mountain Dew and made it look like adding peroxide to it, would make a light.
The person took the liquid from a glow stick and put it in the bottle. The peroxide was the liquid that causes a glow stick to light.
I was at work when I got the video. My brain doesn't work too well at work, especially on Fridays and Mondays.
Glow sticks are a good light. We use them when night scuba diving. They float so they kind of light up the divers. That way, you can keep an eye on everyone.
