50-Watt Lights Made With Water & Use No Energy
Loading ...Posted on: May 1, 2009
Yes it’s true – Liters of light really can light dark spaces for free. During a blackout, a Brazilian man took an empty 2-liter soda bottle, filled it with water and poked them through holes in the roof of his workshop. Viola! Carbon-free light. The light from each 2-liter bottle creates the same amount of light as a 50 watt incandescent bulb.
Now of course this remarkable DIY tip has its limitations. It might not be a good idea to rip a 4″ inch hole in your roof in colder climates. But, this is a great applications for garages, sheds, barns, workspaces, etc. Why turn on an energy sucking bulb in your garden shed when you can get free light from the sun?
Here’s how to make your own Liter of Light. Try it. Then send us your photos of your Liters of Light.
1. Fill a clear 2-liter soda bottle with water.
2. Drop in two caps of bleach (or 6 caps of hydrogen peroxide).
3. Screw on the cap and cover it with a small black film canister.
4. Cut a hole in the roof the exact diameter of the bottles.
5. Place the bottle snuggly through the hole – leaving 1/4 of the bottle exposed to the outside.
6. Run a bead of low-VOC caulk or sealant around the bottle to seal the hole (avoid using any toxic product).
7. Enjoy years of free daylight!
Send us your photos of your Liters of Light. Let us know what you think. Oh yeah . . . these don’t work at night. So, don’t come crying to me.
TIPS:
Try tubular skylights in your home for a more durable fix.

What are the black film canisters for? What do they do? What are alternatives? (And, by the way, they are getting harder and harder to find with all the digital cameras.)

The black film canisters are simply to protect the seal at the top from UV degradation. You can use anything that would block out the light. The film can is great (if you can find them) because it blocks out the UV light and holds up well to weather. But, anything similar will do. Send me some photos if you make one.
