During the day the sun charge the rechargeable battery inside the unit (like a bee :)) that's why we called ourselves PowerBee When dusk falls the charge stored in the batteries power the solar lantern. In the morning the lights turn off automatically and charge up again ready for the night ahead.
These are the best solar ligts I have found - they work even after a dull day. The flickering effect is very pretty too. They come on before it is completely dark and last a good few hours. No need to recharge or change batteries and they have been out all summer! Excellent value and I highly recommend them.
Lovely little Lantern
Nice. Good little lantern for the money and works very well
