Like catching fireflies in a jar (but without all that running around). These sun jars sell out as soon as we get them in the shop. Made with a traditional mason jar and high tech energy efficient lighting! Captured inside the jar are a highly efficient solar cell, rechargable battery, and low energy LED lamps. When the jar is placed in sunlight the solar cell creates an electrical current that charges the battery within hours. This energy is then used at night to power the three LED lamps inside the jar. Original design by Tobias Wong. Please note** This item is backordered and will ship in approx. 14 days (we will notify you of any additional delays).
