The fairy lights is really pretty, both during the day and at night. During the day you can see light blue flowers in the trees at night glowing yellow - either continuously or flashing. At first I found the switch a little difficult to turn when the solar panel is in the earth. But now I've found that you can simply "a" leave him on because the lamp only concerned, when it gets dark. How long it is lit during the winter, I can not say unfortunately, now in the spring stops at a "normal" day (slightly cloudy, no rain) until the next morning by which are more than 9 hours. Therefore, I assume that it is lit in winter for long enough (when I sleep, I do not need decorative lighting in the garden). Solar lights are a great, low-power alternative, which in addition are also used where no power outlet is available. Toll!
