DIY Solar Water Lightbulb Provides 55 Watts Of Light...

What do you get with sunshine and an old plastic bottle filled with water and chlorine? Thanks to Alfred Moser and a group of MIT students, you get a 55-watt solar bulb that refracts sunlight! It’s powerful enough to light up a home but more than that it’s environmentally friendly, inexpensive, and easy to make.

The Liter of Light began in the Philippines with one bottle light. Eventually, the movement grew to brighten up 28,000 homes and the lives of 70,000 people in Metro Manila alone. Now Liter of Light is present in India, Indonesia, and even as far away as Switzerland.

And when the UV deteriorates the plastic you will have a wet mess and a hole in your roof

Light is measured in lumens, not watts.

    60 watts = 800 lumens, for practical intents and purposes. That’s what they mean when they measure light in watts, like it or not

    Unless you have CFL’s or LED lights, in which case it’s a meaningless comparison.

    Victor Gr 60 watts does not equal 800 lumens… Watts don’t relate to Lumens.

    Reply

    In all fairness to him, I think he was assuming the light output of a 60 watt incandescent to equate to 800 lumens. Hence my comment about CFL and LED bulbs.

Doesn’t work at night…

Who would do this?

This site is fake science. Mr. Wizard must be spinning in his grave!!!

Now just need to figure out a way to make it work at night

Most of these would be in your attic. What would happen when the bottle breaks and not only makes a mess in your attic but a hole in your roof?

one week colour change to green:P

only for warm countries… In others the heating energy losses are way too much via the bottle!
And you never get your flatroof rain proof in those chilly rainy countries… not with silicone anyhow!
Think on Northern half of USA/Europe/China/Japan, whole Russia

Lol. Try selling your home after doing that. New roof baby!

Reply

Now you’re stuck with an ugly bottle stuck in your roof.

Reply

Only provides light when the sun is shining… hmm..

Reply

    Right? I have these cool things called windows

    Reply

Spend the money and get a light tube installed. Better than a freaking pop bottle sticking out of your roof.

This is a great idea especially in impoverished countries who have no means or little means of electrical power.

Reply

At least good for the daytime. I’ve seen it for the Philippines and other areas where they have really dangerous electrical wires because they are living in Shacks illegally

Reply

And it would certainly freeze where I live but there are many places that benefit I’ve seen movies of it

Reply

Please stop. That is going to leak.

Reply

I put a couple of these in a patio roof in Australia about 5 years ago, they haven’t leaked but are really for an enclosed space like a garage with no windows. I had an electrician there working with the power all off and the bottles made him nervous! They are surprisingly bright.

What a fantastic idea.

Reply

What about a window lol. G

Reply

? 55 watts . Yeh sure It’s only 50 watts

Reply

Might have problems when it encounters freezeing conditions in northern climes…?

Reply

Good light for the shed
