Use your days to power your nights!

Thanks to NY Mag's Spring 100, I came across IKEA's SOLIG line of solar-powdered lights and lamps. Approved for outdoor lighting and equipped with solar panels, the lamps use sunlight to powder LED lights and don't need to be plugged in. Though not totally eco-friendly, they will at least help decrease electricity costs and can be used anywhere on your plug-less roof (or any well-sunlit areas). There are pendant lamps and desk lights, but these little light globes would be perfect for lighting a summer evening on the patio.
