JOI transforms the energy of a simple tea light to power 8 LEDs; the equivalent of 18 candles and enough to illuminate an entire dining table.
JOI uses thermoelectric technology to convert a temperature difference into electricity.
Place a new tea light into JOI, the candle heats a thermoelectric module at its centre and within a few minutes this creates sufficient electricity to power the LEDs.
No batteries or visible wires. Award winning design & technology. JOI brings light to where there has never been light before.
