Unlike water, which transforms metal into rust, sunlight energizes and invigorates all that it touches, from flowers and skin cells to jaguar-shaped hood ornaments. Harness some solar-powered energy with today's Groupon: for $30, you get one solar-powered spotlight from Hybrid Light (a $59.95 value).

Hybrid Light flashlights use photovoltaic cells to capture both sunlight and room light, soaking up an electron-infused eight-hour charge to prep hand-torches for hours of ghost-story telling and streetlight-staring contests. In addition, the spotlight is waterproof, floats on H2O, and can be used as a life-saving device for shipwrecked Smurfs. Power through a lifetime of nights with Hybrid Light's environmentally friendly darkness defeaters, as all Hybrid Light products come with lifetime guarantees.
