While his Zweistil Bike project brought him many accolades, the Night Ease project may dub Stefan Wallmann as the creator of the "Darth Vader of the night lights…" This one's a simple solar solution that has its bottom covered with solar cells for juicing up. During the day just invert it with the bottom up, on its ring-stand and let it soak in the rays. At night, place it peak-side up and turn it the right way around (it has a tilt switch inside) to activate the light. For the Jedi, may this force be with you!
