Illuminate your camp site the environmentally friendly way, with these solar-powered collapsible lamps. Powered by solar energy, this eco-friendly concept lamp lights up your surrounds when unfolded. Designed by Jesper Jonsson, the solar-powered collapsible lamps come equipped with solar panels that collect energy when the sun is out and store it in a battery. Once the sun goes down, the lamp can be unfolded and its onboard battery powers a set of bulbs inside the lamp to give you light. It also comes with a strap with magnets that lets you hang the lamp in a variety of ways, open of closed. Jesper Jonsson.
