#6 Solar Lantern
Who needs to solar charge a light when the light solar-charges itself? Such is the question begged by the PiSAT K-Light, a solar lantern-slash-flashlight that requires no batteries, is highly water-resistant, lightweight and provides 120 lumens of LED light over a peak 20 hours of runtime (10 hours in sun=20 hours of lantern).
PiSAT is also offering a “Light for Africa” kit, through which every K-Light sold to you equals one K-Light donated to the Koinonia Foundation and its own solar projects in Africa, where grid power may not even be available. The K-Light’s solar panel is attached only by wire to the lantern, meaning the lantern doesn’t necessarily have to be outside to charge. It can attach to a backpack or sit in the car window on the way to an off-grid weekend.
