Jam jars might store jam, but this jar collects and stores sunshine so you can use it at night.

The traditional glass Mason jar houses a highly energy efficient cell, a rechargeable AA battery and low energy LED lights. When the jar is placed in sunlight the solar cell creates an electrical current that charges the battery over a few hours. A perfect garden light or bedroom night light for little ones.

The frosted jar diffuses the light, combining with warm-coloured LED lights for a natural feel. With no visible controls on this sun jar, a clever light sensor inside automatically activates the lights upon darkness.
