I would love to be able to save up enough money to buy a dozen of these and let them light up a room - how romantic would that be! They are $39.99 at Perpetual Kid ... "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 lamps. 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 three LED lamps inside the jar".
