The Sun Jar is made with a traditional Mason Jar and high tech energy efficient lighting! Captured inside the jar are a highly efficient solar cell, rechargeable battery and low energy LED lamp. When the jar is placed in sunlight, the solar cell creates an electrical current that charges the battery over a few hours. This energy is then used at night to power the LED lamp inside the jar. The light emitted is diffused by the frosted jar and gives the appearance of sunlight. (A warm – coloured LED light is used to give a more natural light). You may have noticed that there is no switch on the Sun Jar – in fact there are no visible controls at all. A light sensor inside the jar automatically activates the lights when it gets dark (or the lights are turned out!).* Mason Jars are beautiful and – by their very nature – watertight, so the Sun Jar can happily be left outside in any weather conditions. A perfect garden light or nightlight for a child’s bedroom.
