If only Benjamin Franklin and Nikola Tesla were around in the same century, they might have teamed up and made a product as creative and useful as this LED Candle-Powered LED Lantern.
This innovative lantern emits a surprising amount of light, considering its power source. No power cord or batteries are required; it generates its own electricity by harnessing the heat energy of a single candle flame to run eight LEDs. It produces the equivalent light of about 18 tealight candles (70 lumens), more than enough to read by or illuminate a table top.
The lantern's operation is based on a phenomenon known as the Seebeck effect, using thermocouple technology to generate an electrical current by exploiting the temperature difference between the inside of the lantern and the cooler outside air. As long as the candle inside the lamp housing is burning, the LEDs will continue to emit light.
A useful lamp wherever an electrical outlet isn't available, and great to have on hand in case of power failures. Three tealights included. Made in Canada.
