Made with a traditional Mason jar and energy efficient lighting, Sun jar collects and stores sunshine so you can use it at night. Inside the jar are a highly efficient solar cell, rechargeable battery and low energy LED lamps. When the jar is placed in direct 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 three LED lamps inside. The Sun Jar can be left outside in all weather conditions; the perfect garden light or night light for a kid's bedroom.
