Firewinder It is a very particular lamp. It can not be used indoors because its source of energy is the wind. It is designed to be installed in gardens, terraces or large farms because it is activated exclusively by wind, without cables or batteries.
Its system detects the force of the wind and illuminates the sheets that form them. And if there is no wind ?, then there is no light either because it does not accumulate energy. It is very easy to install, you just have to hang it on a tree, on the roof of a terrace or on the wall, for example.
The truth is that they are a great idea to save energy, but very little practice in places where the wind is not a constant.
