The name should not be called wind generator, but storm generator. Because unfortunately you have to blow very strongly, so that the LED's also really start to shine! Fortunately, the wind / storm generators can be employed also in the outdoor area. But, as I said, a light breeze is not enough to supply the LEDs with power. A stronger wind brings only small rotors to rotate, but the lights come on only when a really strong gust on the small storm generator acts.
