Caframo JOI thermoelectric lantern / lamp

JOI uses thermoelectric technology to convert a temperature difference into electricity. The lantern uses a unique power source that is easy to use, economical and found in every home - the common tea light candle. The patented JOI design activates its LED lights by creating a hot side and a cold side on the module and when this happens a principle called the “Seebeck Effect” causes electrons to flow within the module. The average tea light candle will power the Thermologi JOI for about 4 hours. Create a sense of wonder while delivering functional power. No batteries, cords or solar hassles. JOI brings light to places there has never been light before.
