A Water Bottle by Day, a Lantern by Night
Now what could be more eco-friendly or useful than this – a water bottle lid which can fasten onto most water bottles which turns into a light in the night! Great for camping and the great outdoors even for drives in the night. You almost always need water and light is extremely useful in the dark.
The best part about this nifty device is that the cap works on solar power, thus providing green and clean energy. The lid has a solar panel built in and this can covert the solar power into energy to power the lantern. It gives out bright white light, with four LEDs.
And it goes off automatically in the daylight. No batteries, rechargeable or others to worry about. But you have to buy your own bottles separately from the lids, so make sure to get the right sized bottles. Click for more on this device
